PART 01

Overview

Where it came from, why it matters, and how it changed year to year.

The story

The classic Defender is what happens when a company finds the right answer in 1948 and spends the next six decades only fixing the bits that hurt. Under the slab-sided aluminium skin sits a steel ladder frame, two beam axles and bolted-on panels. It is not quick, quiet or watertight. It is, however, the vehicle that taught several generations of overlanders that you can rebuild anything in a campsite if the thing was designed by people who expected you to.

FROM SERIES TO ONE TEN

By the early 1980s the leaf-sprung Series III was feeling its age. Land Rover's fix was to raid its own luxury shelf: the One Ten of 1983 got coil springs front and rear and permanent four-wheel drive with a centre differential, both lifted from the Range Rover Classic. The short-wheelbase Ninety followed in 1984 and the long One Two Seven in 1985.

Engines were a grab bag at first: 2.25-litre petrol and diesel carry-overs, a 2.5 diesel making a heroic 68 hp from 1984, and the Rover 3.5 V8 that turned the 90 into something approaching brisk. A Diesel Turbo arrived in 1986, and in 1990 the 200Tdi finally gave the truck a diesel worth having, with 107 hp and 195 lb-ft. It is still the engine many gray-market shoppers go looking for, because there is very little on it that a laptop needs to diagnose.

THE DEFENDER NAME, AND AMERICA

When the Discovery arrived in 1989, the plain-named Land Rover needed a name of its own. It became the Defender 90, 110 and 130, with badges changing for the 1991 model year. The 300Tdi replaced the 200Tdi in 1994, the five-cylinder Td5 came in 1998, and the Ford-sourced 2.4 'Puma' diesel with a six-speed arrived in 2007. Through all of it, the basic shape barely moved.

North America's official ration started with the 1993 NAS (North American Specification) Defender 110: 525 trucks, 500 for the US and 25 for Canada, all Alpine White, all 3.9-litre V8 with a five-speed manual, full external roll cage and a numbered badge. The NAS Defender 90 followed from 1994, first as a soft-top and later with a removable fibreglass roof panel or a full hard-top, and the last 1997 trucks got a 4.0 V8 and a ZF four-speed automatic. ECD puts total NAS production at about 7,059.

WHAT MADE IT SPECIAL

The genius is that almost nothing is precious. Body panels are aluminium bolted to a steel frame, the axles are solid, the transfer box is a two-speed LT230 with a centre diff you lock by hand when the going gets slippery, and the parts catalogue is still enormous decades later. Owners fix their own swivels, timing belts and outriggers because the job is genuinely within reach, and an aftermarket from Solihull to Vermont exists to help.

It also leaks, rattles, rusts at the steel bits and steers like a boat with opinions. That's the deal. In return you get short overhangs, a body you can see the corners of, a cabin you can hose out, and a silhouette so recognizable that Ineos built a whole company, and the Grenadier, around missing it. Love it or hate it, nobody has ever mistaken one for a crossover.

HOW IT ENDED, AND THE 25-YEAR AFTERLIFE

US sales stopped after the 1997 model year; regulations arriving for 1998, including airbag and side-impact door requirements, made the old body uneconomic to certify. Production for everyone else ended on 29 January 2016, after a 67-year run counting the Series, and the name came back in 2020 on the unibody, independently sprung L663 Defender. Whatever you think of the new one, it ended the era of the separate chassis and beam axles at Land Rover.

Meanwhile federal law did the rest. NHTSA lets a vehicle at least 25 years old, counted from its date of manufacture, be imported without meeting FMVSS, so every year another batch of Euro-market 90s and 110s becomes legal. That market has teeth: in 2014 Homeland Security agents seized more than two dozen Defenders imported by one North Carolina enthusiast over suspected VIN swaps; after a legal fight they were found correctly imported and ordered returned in 2015. Not every owner was so lucky: Hagerty reported one whose undocumented truck was seized and apparently lost. Buy the paperwork before you buy the truck.

SIDEBAR · NAS DEFENDERS

The 7,000-ish Defenders America got officially

1993 NAS 110: 525 built over about a year in a special area at Solihull, 500 for the US and 25 for Canada, all Alpine White, with 3.9 V8, five-speed manual, full external cage, basket roof rack, deep-dish wheels and a sequence-numbered NAS badge. Clean ones now trade near $200,000, according to Atlantic British.

1994–1997 NAS 90: soft-tops first, then a removable fibreglass roof panel and a full hard-top; ECD says cracking fibreglass tops were an early problem. Colours across the run included Coniston Green, Portofino Red, Arles Blue, Beluga Black, Alpine White and AA Yellow. The 1997 run added a 4.0-litre V8 and ZF four-speed automatic, and the run closed with the 300-unit Limited Edition D90 station wagon in Willow Green with a white roof.

PART 02

Specs & capability

How it’s built, what it can do, and what fits under it.

How it’s built

The 90/110 is a Series Land Rover rebuilt on Range Rover hardware: a boxed steel ladder frame carrying beam axles on coil springs, permanent four-wheel drive through a two-speed transfer box with a lockable centre differential, and aluminium body panels bolted to a steel bulkhead. That layout makes it tough and endlessly repairable, and also explains its two big weaknesses: steel parts rust where mud and water sit, and the drivetrain was built for a 1980s power level.

CHASSISSteel ladder frameMild steel; rear crossmember and outriggers rot first.
BODYAluminium panels on steel bulkheadPanels oxidise and lift paint rather than rusting; the steel bulkhead and footwells do rust.
SUSPENSIONCoil springs, beam axlesFront and rear coils, lifted from the 1970 Range Rover.
4WDPermanent, lockable centre diffLock it before prolonged wheelspin; the stock diff's small gears can fail.
TRANSFERLT230 two-speedUsed through the Defender run (early V8 One Tens had the LT95), plus Discovery 1 and Range Rover Classic.
STEERINGSwivel-ball front axleChrome balls and seals need periodic attention; preload set with shims.

PART 03

Buying one

What to pay, what to check, and how to tell a good one from a clone.

What they cost

NAS trucks carry a big premium over gray-market imports, and original, documented 1993 110s are the top of the market; Tdi imports are the affordable way in.

Gray-market 110, project or tired driver$17k–32k
Gray-market 90 or 110 Tdi, good driver$30k–56k
NAS Defender 90, driver$40k–60k
NAS Defender 90, excellent$65k–106k
NAS Defender 110 (1993)$62k–135k+

Based on Bring a Trailer sold results in 2025–26: 14 NAS D90s ($40,000–106,000, median about $59,000), three 1993 NAS 110s ($62,500–135,000), 10 Euro 90s and 9 Euro 110s ($17,250–69,003, apart from two LS3-swapped 90s at $61,000 and $145,500). Atlantic British puts the very best NAS 110s near $200,000. Prices move; checked October 2026. See live listings below.

What to check before you buy

  1. 01
    Paperwork and VIN firstMatch the VIN plate on the brake servo with the number stamped on the front chassis rail. For gray-market imports, make sure the build date really is 25+ years old; federal agents have seized Defenders over alleged VIN swaps, and owners without paperwork lost them.
  2. 02
    Rear crossmemberIt takes towing and winching loads and rots from the inside out. Fibreglass, fresh underseal or chunky checker plate can hide it, so get under with a light and ask for the underside to be cleaned.
  3. 03
    Bulkhead, footwells and outriggersCheck the bulkhead sides, bottom corners and the top under the vent flaps, plus the footwells and the outrigger behind the front wheel. Repair is real money; a new bulkhead runs about £1,600 in the UK.
  4. 04
    Swivel balls and steering playPitted chrome balls chew their seals and wear the swivel pins. Vague or wobbly steering with excess play points here; budget for rebuild kits if the balls are rusty or weeping.
  5. 05
    Transfer box noise and leaksListen for whine and clunks in low range. Oil leaking from the LT230 can coat the transmission handbrake shoes; check the rear output seal and intermediate shaft area.
  6. 06
    300Tdi timing belt historyAsk whether the revised timing kit (Land Rover STC4096L-type, with flanged crank pulley and spaced idler) has been fitted. Early setups could let the belt track off and wear.
  7. 07
    Td5 oil in the loomPull the barrel connector between the engine and injector harnesses. Oil there means it's wicking toward the ECU under the seat.
  8. 08
    NAS authenticityA real 1993 NAS 110 or 1994–97 NAS 90 carries a numbered NAS badge and a US-market VIN. Plenty of Euro trucks have been dressed up as NAS; check against the registry discussions on Defender Source.

Spotting the real thing

Defenders get cloned, re-dated and dressed up as NAS trucks, and a gray-market import with a mismatched VIN can be seized. Check the numbers before you check the paint.

  1. ID
    VIN plate and chassis stampThe VIN plate sits on the bulkhead or brake servo under the bonnet; match it to the number stamped on the front chassis rail and the title. For an import, the build date must really be 25+ years old.
  2. ID
    Rest-of-world VINNinety/One Ten VINs start SALLD. Position 6 is V for Ninety or H for One Ten; position 7 is body (A regular, B Ninety Station Wagon, H High Capacity Pickup, M One Ten Station Wagon); position 8 is engine (B 2.5 TD, C 2.5 D, D 2.5 petrol, F 2.5 Tdi, G 2.25 D, H 2.25 petrol, V V8).
  3. ID
    Genuine NAS trucksNAS Defenders carry a US-format 17-character VIN (RM Sotheby's examples: SALDV2285RA941249 for a 1994 D90, SALDV2246VA118787 for a 1997), a numbered NAS badge, a full external roll cage, larger side indicators and taillights, factory air and four-wheel discs. All have the 3.9 or 4.0 V8.
  4. ID
    200Tdi or 300Tdi?The 200Tdi has two V-belts and a big aluminium block-to-sump strengthener; the 300Tdi has a single serpentine belt, no strengthener, a smaller water pump mounted higher and a piston-type vacuum pump.
  5. ID
    Heritage certificateThe British Motor Museum's Heritage Certificate copies the factory ledger entry (build and despatch dates, engine number, colour, equipment) and covers Land Rovers from 1948 on. Useful for proving a build date or NAS spec.

Recalls & service bulletins

Open recalls follow the VIN, not the model. Run yours through NHTSA before you buy, and ask the seller for dealer records showing recall work.

Importing & legality

Only the NAS trucks (1993 110, 1994–97 90) were sold new in the US, so every other classic Defender here is a gray-market import. NHTSA lets a vehicle in without meeting federal safety standards (FMVSS) once it is at least 25 years old, counted from its date of manufacture, declared under Box 1 on the HS-7. In October 2026 that means trucks built before October 2001: 200Tdi, 300Tdi, V8 and early Td5 Defenders. A newer Defender can't be made to comply, and Puma trucks (2007 on) won't start qualifying until 2032.

The EPA side is separate. On Form 3520-1, exemption code E covers vehicles at least 21 years old (calendar year of manufacture subtracted from year of import) in original, unmodified configuration. A truck with a replacement engine doesn't qualify unless it's the same engine model as original, so an engine-swapped Defender should be imported before the swap, not after.

Enforcement is real. In 2014 Homeland Security agents seized more than two dozen Defenders imported by one North Carolina owner on suspicion that VINs had been swapped to beat the 25-year rule; in 2015 they were found to have been correctly imported and ordered returned, after a pro bono legal challenge. Make sure the VIN plate, chassis stamp, title and build date agree before you pay, and a Heritage Certificate helps.

State rules come last and matter most in California. Its smog-check exemptions cover gasoline vehicles of the 1975 model year and older and diesels of the 1997 model year and older, but a direct import from 1975 on that was never certified for California is supposed to get a CARB Certificate of Conformance after a laboratory test, and ECD warns a classic Defender engine can keep the truck off California roads. Check with your DMV and, in California, with CARB before you buy.

Rules change and vary by state and country. Confirm with your DMV and a licensed importer before you buy.

Owning one

Baseline service, the repairs you’ll actually do, and where the manuals live.

Post-purchase baseline

After you buy it

Assume nothing has been done. Most of these trucks are 25 to 40 years old and have usually had several owners. Change every fluid, re-grease the swivels and propshafts, and confirm the timing-belt history on a Tdi. Specs differ between the US V8 (NAS) trucks and the 200/300Tdi, Td5 and Puma diesels, so identify the engine and gearbox first. Fill the axles, transfer box and swivels to their level plugs on level ground rather than trusting a book capacity.

Engine oil & filterNAS 3.9 V8: API SG/SH, SAE 5W-30 or 5W-40 · ≈6.7 L with filter. 300Tdi: ≈6.65 L with filter (Comma lists 10W-40). Td5: 7.8 L with filter, 5W-40 or 5W-50 (Haynes). 2.4 Puma (2007–12 MY) and 2.2 (2012 MY on): 6.85 L service fill with filter, 5W-30 to WSS-M2C913-B or C, or WSS-M2C934-B for the 2.2 with DPF (Land Rover oil chart)At purchase, then every 5,000–6,000 mi (Comma: 10,000 km / 6 months for the 300Tdi)

The V8 and Tdi engines use the short spin-on filter. The Td5 also has a centrifugal oil-filter rotor that needs servicing.

Air filterOE-type element for your engineAt purchase; more often in dust

Check that the dump valve at the bottom of the airbox isn't split, because it lets unfiltered air in.

Fuel filterDiesel: OE-type element (Tdi: AEU2147L). V8: threaded inline EFI filter ESR4065 (Rovers North lists it for the NAS 90 and 110; Lucky8 for Defender '94–'97)At purchase
Glow plugs / spark plugsTdi: ETC8847 glow plugs ×4. V8: Rovers North lists ERR3799 for the 3.5/3.9/4.0/4.2 EFI V8; gap [CONFIRM IN MANUAL]At purchase if there's no record, or if cold starts are slow

A cold start that smokes and stumbles on a Tdi usually means one or more glow plugs have failed.

Timing belt (300Tdi / 200Tdi)Revised kit (flanged crank pulley, idler, tensioner). V8 and Td5 use timing chains, not beltsEvery 60,000 mi or 5 years per Lucky8. Glencoyne says 60k or 72k depending on model. Do it at purchase if there's no record

Land Rover revised the 300Tdi tensioner, idler and bottom pulley because belts were wearing early. A yellow paint square on the timing cover was meant to show the fix had been done, but it isn't reliable.

Coolant50/50 ethylene glycol antifreeze and water · NAS V8 ≈12.8 L. 300Tdi ≈11.1 LAt purchase, then every 2 years (Comma: 40,000 km / 24 months)

The aluminium V8 can't take overheating. Check the radiator for blocked fins and the viscous fan for drag while the system is drained.

Manual gearbox (R380 / LT77)Handbook: ATF M2C33-F or G (as quoted on AULRO) · ≈2.4 L (Comma lists its 75W-80 MTF for the 300Tdi R380)Drain and refill at purchase

Check the level at the side filler with the truck level. A notchy second gear or third-gear synchro problem on an R380 isn't fixed by changing the oil. A 1993 NAS 110 (LT77) data set lists 2.67 L.

Automatic (1997 NAS D90 ZF 4HP22)Dexron IID ATF · 9.1 L listed total fillDrain and refill at purchase

Draining the pan only replaces part of the 9.1 L. Do two drain-and-fills rather than a pressure flush on an old box, and change the pan filter.

Transfer box (LT230)EP90 / 80W-90 gear oil, API GL-4 or GL-5 · ≈2.3 LAt purchase (Comma: change every 40,000 km / 24 months)

The filler at the back of the case is tapered, so it feels tight before it is fully seated. Don't overtighten it. Use a new copper washer on the drain plug. The intermediate shaft and rear output seals are the usual leaks.

Front & rear axlesEP80W-90 GL-4/GL-5 · front ≈1.7 L. Rear ≈1.7 L on the Rover axle (one data set lists 2.3 L for the NAS D90). 110/130 (Salisbury) rear 2.26 L, 90 rear 1.7 L (Haynes)At purchase, then every 2 years (Comma: 40,000 km / 24 months)

Fill each axle to the level plug on level ground. The Tdi manual figure is 1.7 L, but one Defender2 owner got nearly 2 L into a rear axle on level ground, so trust the level plug rather than the book. Use a new drain-plug washer.

Swivel housingsEarly trucks: EP90 · 0.35 L per side (handbook). From about 1994: one-shot swivel grease STC3435, one sachet per sideCheck at purchase and every service. Comma says change every 40,000 km / 24 months

Lucky8 lists the STC3435 sachet for the NAS Defender 90 ('94–'97) and the Defender 110 ('93), but a 1997 NAS D90 data set still lists 0.35 L of EP oil, and JC's British 4x4's 52,500 km service checklist for the NAS 90 and 110 also calls for EP gear oil in the swivels, so check what is actually in yours before topping up [CONFIRM IN MANUAL]. An AULRO owner's 1994 swivel took about 450 ml to reach the level plug, so fill until it just dribbles out. Weeping seals mean the chrome ball is pitted. See the repairs above.

Power steering & steering boxDexron IID ATF (Haynes) · 2.8 L system. The 1993 US service checklist says ATF Type F instead, so check what's in yours before topping up. Steering box: EP80W-90Check at purchase

Leaks from the box's input seal or sector shaft are common. Top up and watch the level.

Brake & clutch fluidDOT 4At purchase, then every 18 months (Comma: change every 30,000 km / 18 months)

The hydraulic clutch shares the fluid type. A soft clutch pedal usually means the slave cylinder is failing.

Propshaft grease pointsMultipurpose lithium grease on the UJs and sliding jointsAt purchase. Comma says check UJs every 12 months and sliding joints every 24 months

A clunk on take-up usually means a dry UJ or a worn sliding spline. Grease them before chasing the gearbox.

For the hands-on owner

Common repairs

The jobs owners actually end up doing, rated for a competent home mechanic with a decent tool kit. Always confirm torque figures, fluids and procedures against the factory service manual for your VIN, and work safely — support the truck on stands, never just a jack. You do this work at your own risk; see the disclaimer. Some parts links are affiliate links.

THE FIXSupport the chassis on stands, pull the wheels and disconnect the track rod. Rebuild with new bearings, seals and gaskets, fit the swivel pins with shims, torque lower then upper bolts, and check turning effort with a spring balance at the track-rod bore before fitting the seal. Workshop-manual text quoted on Defender2: 1.16–1.46 kg once initial inertia is overcome, with the swivel bearing housing-to-axle bolts at 73 Nm, lower swivel pin bolts at 25 Nm and top pin bolts at 65 Nm (thread sealant STC50552 on the pin bolts). The manuals disagree, though: a RAVE table quoted on AULRO matches those bolt torques (65 Nm upper, 25 Nm lower, 73 Nm housing-to-axle), but a 05/99 workshop-manual table quoted in the same thread gives 78 Nm for both upper and lower pins, and a Defender2 owner reports the older manual's 22–28 Nm lower figure against 78 Nm in a newer one. The 1983–1995 workshop manual and Haynes give a turning effort of 3.6–4.5 kg rather than 1.16–1.46 kg. Use the manual for your exact axle [CONFIRM IN MANUAL]. Add or remove top-pin shims to adjust, then refill with one-shot grease.

DIFFICULTY · 1 / 5TIME · Short jobSHOP COST · Price of a grease pack
SYMPTOMSGrease smeared on the inside of the wheel and around the swivel seal retainer.
THE FIXRemove the seal retaining ring (six 8 mm nuts on the Defender), clean the seal area, then turn the wheel to full lock away from the side you're filling so the housing doesn't overlap the ball, and fill through the filler plug. One pack per side is roughly right; the grease is runny.

300Tdi timing belt with revised kit
DIFFICULTY · 3 / 5TIME · Several hoursSHOP COST · Parts plus labor
SYMPTOMSDue on the service interval, belt edge wear, or debris inside the timing cover; early-type kits can let the belt track off.
THE FIXLock the cam and crank with the timing tool, remove the front cover, fit the revised kit (flanged crank pulley, idler with integral spacer, tensioner, gasket). On early-type engines, remove the separate spacer washer because the new idler includes it. Land Rover later reduced the torque used to tension the belt (applied to the tensioner before its bolt is tightened) to 11 Nm, according to both Glencoyne and an AULRO member, and earlier manuals may not include the change: Glencoyne gives the old figure as 15 Nm, the AULRO member as 14 Nm. This is the belt-tension setting, not the bolt's clamping torque.

Td5 injector harness oil leak
DIFFICULTY · 2 / 5TIME · Short for the injector harness; much bigger if the main loom is contaminatedSHOP COST · Parts plus labor
SYMPTOMSOil and dust on the ECU plug under the driver's seat, misfires or running issues.
THE FIXThe injector harness lives inside the rocker cover; oil wicks out through the plug seal and along the main loom to the ECU. Remove the acoustic cover, unplug the barrel connector and check for oil. Replace the injector harness; if oil has reached the main engine loom, replace that too. Light contamination can be flushed with contact cleaner, but replacement is the real fix.

SYMPTOMSOil running down the back of the transfer box, contaminated transmission handbrake.
THE FIXConfirm the source first: on an LT230 the intermediate shaft is a common leak. Drop the propshaft, remove the rear flange nut and flange (can be done in situ), tap off the dust cap, replace the rear seal and felt washer, then refit with a new M20 nyloc nut and fresh flange bolts torqued to spec.

Land Rover 90 / 110 / Defender questions, answered

What's the biggest tire I can fit without a lift?

235/85R16 is the classic factory size on 110s and the 'sweet spot' most owners recommend; NAS D90s came on 265/75R16. 255/85R16 (about 33") is the popular upgrade and generally fits at stock height, but owners report rubbing on the front radius arms at full lock (fix by winding out the steering stops), against the 45 L auxiliary tank on 110s, and close to the spring brackets at full compression on 90s.

SOURCE · AULRO / DISCOWEB
Can I import a Defender into the US?

Yes, if it's at least 25 years old counted from its date of manufacture: NHTSA lets those vehicles in without meeting FMVSS (declared under Box 1 on the HS-7). Newer trucks must comply, which a classic Defender can't. Check EPA and your state's emissions rules too, and make sure the VIN, chassis number and build date line up.

SOURCE · NHTSA / CBP
Which Defenders are 25-year-eligible right now?

Everything built at least 25 years before the import date, so in late 2026 that's trucks built up to late 2001. That covers 200Tdi, 300Tdi, V8 and early Td5 Defenders (the Td5 arrived in 1998). The Ford 'Puma' Defenders from 2007 won't start qualifying until 2032.

What is a NAS Defender?

North American Specification Defenders were the ones Land Rover sold new in the US and Canada: 525 1993 Defender 110s (500 US, 25 Canada) and Defender 90s from 1994 to 1997, all V8. About 7,059 were built in total.

SOURCE · ATLANTIC BRITISH / ECD
Why did Land Rover stop selling the Defender in the US after 1997?

Regulations taking effect for 1998, including airbag and side-impact door requirements, made it too expensive to keep the old body compliant. The Defender name returned to US showrooms in 2020 on the all-new L663.

SOURCE · ECD / RM SOTHEBY'S
Which engine should I buy?

For a gray-market truck, the 300Tdi is the simple, mechanical favourite; check the revised timing kit has been fitted. The 200Tdi is cruder but similar. The Td5 is more powerful (122 hp) but electronically managed, so check for oil in the injector loom. In the US, NAS trucks are all 3.9/4.0 V8, which is thirsty but easy to service.

SOURCE · WIKIPEDIA / AULRO
What fuel economy should I expect?

ECD estimates 12–16 mpg for the factory V8 (12–14 in real-world use), 23–27 mpg for the 300Tdi, 22–26 mpg for the Td5 and 20–25 mpg for the Puma diesels; it doesn't say how they were measured. Roof racks, big tyres and a heavy right foot will take you well under those.

SOURCE · ECD
How much can a classic Defender tow?

CarsGuide lists 3,500 kg (7,716 lb) braked for 2004 Defender 90, 110 and 130 variants, and GoAuto gives the same 3,500 kg braked / 750 kg unbraked for the 2009 Defender 90. Unbraked trailers are limited to 750 kg. Check your own truck's plate and handbook; the rear crossmember condition matters more than the brochure number.

SOURCE · CARSGUIDE / GOAUTO
When do I lock the centre diff?

Whenever you expect prolonged wheelspin: mud, snow, ice, sand, steep loose climbs. The LT230's stock centre diff has small gears that can fail if a front wheel spins for long, and the diff lock removes that risk. Unlock it on grippy surfaces to avoid driveline wind-up.

SOURCE · LR PARTS / ASHCROFT
Does it rust?

The aluminium panels don't rust, but they oxidise, lifting paint and eventually perforating. The steel parts rust: chassis rear crossmember, outriggers, bulkhead footwells and corners, door frames and hinge mounts. Budget for welding unless the truck already has a galvanised chassis.

Who makes the good stuff, where owners gather, and who to watch.

Common modifications & who does them

SUSPENSION LIFTStock springs sag with age and accessories. Heavier springs and better shocks restore ride height and add an inch or two for 255/85 tyres.
LOCKERS & DIFFSOpen diffs front and rear; an air locker or ATB limited-slip transforms progress on articulated ground.
TRANSFER BOX & DRIVELINERebuilt or brand-new LT230s, taller ratios for big tyres, ATB centre diffs and heavy-duty 300M shafts.
PARTS & RESTORATIONSeals, swivel kits, panels, NAS-specific trim, timing kits: these are the US and UK catalogues the community actually uses.
GALVANISED CHASSISWhen the frame is past welding, a hot-dip galvanised replacement chassis is the permanent fix.
ROLL CAGES & PROTECTIONThe NAS trucks wore cages from the factory; external and internal cages are a common addition for serious trail use.
