“A 2,000-lb ladder-frame 4x4 that Consumer Reports said tipped over and the trail crowd says goes everywhere. Both had a point. Give it some lift, a locker and lower gears and it climbs things that embarrass trucks three times its size.”

PART 01

Overview

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

The story

The second-generation Jimny arrived in 1981 as the export SJ410, a little 1.0-litre box on a ladder frame with leaf springs and solid axles at both ends. In November 1984 Suzuki added the 1.3-litre SJ413, and in late 1985 it brought that truck to the United States as the Samurai, the first four-wheeled vehicle Suzuki sold there. It cost about two-thirds as much as a new Jeep Wrangler and weighed roughly 2,100 lb. Americans bought 47,000 in the first year. Then Consumer Reports rolled one.

FROM SJ410 TO SAMURAI

The SJ410 replaced the LJ80 in 1981 and was sold as a soft top, a hardtop and a long-wheelbase pickup. Australia called it the Sierra, and Holden sold it as the Drover. The SJ413 that followed in 1984 brought the 1,324 cc G13A four, a five-speed gearbox, front disc brakes, an anti-roll bar and a new dashboard. In Japan it was the Jimny 1300 (JA51), at the time the biggest engine Suzuki sold.

The US Samurai launched in California in November 1985 as a 1986 model, already on the wider track that Suzuki later used for the Samurai worldwide. Suzuki's 1986 brochure lists 1,300 mm front and 1,310 mm rear, against about 1,210 mm on the narrow SJ. It quoted 64 hp, 74 lb-ft, 8.1 inches of ground clearance and 43/38-degree approach and departure angles. MotorTrend timed it at 16.9 seconds to 60 mph. Nobody bought one for the acceleration, and by mid-1988 Americans were buying 8,000 a month.

THE CONSUMER REPORTS AFFAIR

The July 1988 issue of Consumer Reports rated the Samurai 'Not Acceptable', the first time the magazine had used that rating, saying it tipped up in its short-course accident-avoidance maneuver. According to evidence Suzuki cited in court, the Samurai went through more than three dozen runs on CU's established course with no tip-up. CU then modified the course, and a test driver tipped it onto its outriggers. In June 1988 CU showed reporters video of the tip-ups and asked for a recall. NHTSA denied two 1988 petitions for a defect investigation, saying the evidence didn't show that a vehicle defect, rather than the driver or the environment, caused the rollovers.

The damage was done anyway. Reuters reported that Samurai sales fell about 70 percent. In 1996 Suzuki sued Consumers Union for $60 million over CU's renewed claim that the Samurai 'easily rolls over in turns'. A district judge threw the case out, and in 2003 the Ninth Circuit revived it. In July 2004 the two sides settled with no money paid. CU said it never meant that the Samurai easily rolls over in routine driving, but it stood by its tests, while Suzuki disputed them. NHTSA's Michigan crash data for 1986–90 put the Samurai's single-vehicle rollover rate (29 percent) next to the Wrangler's (28 percent) and below the CJ-7's (46–48 percent). It is still a short, narrow, tall truck, though, and MotorTrend's verdict is that it tips more readily in sudden swerves than most 4x4s.

THE ROCK-CRAWLING CULT

What sank the Samurai as a commuter made it a legend on the trail. It weighs little, it's narrow, and it has a real transfer case with low range. Lifted on a spring-over, it can be geared down with transfer-case gear sets as low as 6.4:1 and wedged into lines that big trucks can't fit. Trail Tough, a shop started by Samurai enthusiasts in the 1980s, still sells spring-over kits, Sumo gear sets, knuckle-over steering and 1.6- to 2.3-litre Suzuki engine conversions. In 2007 two Chileans drove a modified SJ413 to 6,688 m on Ojos del Salado, a Guinness-certified altitude record for a four-wheeled vehicle at the time.

The other big upgrade is an axle swap. Trail-Gear and Low Range Off-Road sell kits that put 1979–85 Toyota truck axles under a Samurai. On Zukiworld, one builder wrote in 2006 that the Toyota swap had 'become as common as a SPOA lift.' The Toyota axles are about 5 inches wider, take the same brake-line fittings and have a huge aftermarket, but Samurai steering won't fit them. Some builders prefer Dana 44s instead.

SANTANA, GYPSY AND HOW IT ENDED

Spain's Santana built SJs in Linares from 1985, and because they were more than 60 percent local content they got around Europe's quotas on Japanese imports. Santana built Samurais with Peugeot and later Renault diesels until about 2003–04. In India, Maruti launched the long-wheelbase Gypsy in December 1985. In 1993 it got the 90 mm wider track and became the MG410W, then became the 1.3-litre Gypsy King in 1996. It stayed in production until 2018, a staple of the Indian Army and police.

In the US the Samurai lost its rear seat for 1994 and 1995, because adding the required rear shoulder belts would have meant re-engineering it. It was gone after 1995, replaced in spirit by the Sidekick. Japan got a coil-sprung version (JB32) in 1995, and the line ended there in 1998, when the JB23 Jimny took over.

SIDEBAR · 6,688 METRES

The Samurai that topped the Jeep

On April 21, 2007, Chileans Gonzalo Bravo and Eduardo Canales drove a modified 1986 SJ413 Samurai to 6,688 m (21,942 ft) on Ojos del Salado. That beat the record for the highest altitude reached by a four-wheeled vehicle, set by a team in a Jeep Wrangler. It was their third attempt, after bad weather and then an engine fire, and the truck ran a supercharged Suzuki G16A engine.

The Jeep team had left a sign at the top: 'Jeep Parking Only: All others don't make it up here anyway.' The Chileans brought it home. Guinness certified the record that July, and a Unimog later beat it.

Specs & capability

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

How it’s built

The SJ is a scaled-down 1950s truck, and that's the point. A separate ladder frame carries a steel body. Both axles are solid and hang on semi-elliptic leaf springs. A gear-driven two-speed transfer case sits behind a five-speed manual, and the front hubs are manual Aisin lockers. There's no center differential, so 4WD is only for loose surfaces. Steering is recirculating ball, and the US truck had power front discs and rear drums.

Buying one

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

What they cost

Samurai prices have climbed from throwaway to collectible. Low-mileage stock trucks and well-built engine-swapped trucks bring the most.

Project / tired driver$5k–9k
Good driver or modified$8k–17k
Exceptional low-mile or high-end build$20k–25k

Based on 22 Bring a Trailer sales from September 2025 to October 2026: $5,500 to $25,000, median about $9,400. A 7k-mile 1987 sold for $24,000 and a 1.6 16V-powered 1987 for $25,000. Prices move; checked October 2026. See live listings below.

What to check before you buy

  1. 01
    Rust and hidden trail damageMotorTrend's advice is to check the underbody carefully, for rust and also for dents, scrapes and dried mud in hard-to-reach places, which all point to a hard off-road life. If you want a stock truck, an unmodified Samurai is less likely to have been abused.
  2. 02
    Transfer case mounts and frame hangersTrail Tough calls cracked transfer case mounts and a wallowed-out, bent rear frame hanger common Samurai stress failures, and lower gearing makes them worse. Look at the rubber mounts and the frame brackets on both sides of the case.
  3. 03
    Transfer case that won't shift or sticks in neutralMotorTrend lists bad transfer-case bushings that can lock the case in neutral. The usual culprit is the plastic 'shift sheet' under the lever. It's a cheap OEM or Delrin part, but check that 4WD and low range both engage.
  4. 04
    Oil leaks and carburetor mannersMotorTrend's known trouble spots include oil leaks at the distributor, leaking brake master cylinders, fiddly carburetors on 1986–89 trucks and failing ECMs on fuel-injected ones. A clean cold start and a steady idle are worth a lot.
  5. 05
    Quality of past modificationsMost Samurais have been modified. A well-built spring-over or engine swap saves you money; a bad one costs you. Check the steering geometry, brake lines at full droop, driveshaft angles and welds. Swapped engines may not pass emissions in some states, and Trail Tough notes that 1996-and-later 1.6 donors are OBD-II and won't be smog-legal in California.
  6. 06
    Is it an automatic? It's a swapEvery US Samurai had a manual gearbox, so an automatic means someone swapped it in. Ask what was done and look for the paperwork.
  7. 07
    Front knuckles weeping gear oilOil-soaked knuckles, loose steering and a vague front end point to worn kingpin bearings and inner axle seals. Trail Tough's rebuild kit covers both sides, and it's a common catch-up job.
  8. 08
    Know which Samurai you're buyingFor the US, 1986–89 trucks are carbureted (AMSOIL's lookup lists engine code 5) and 1990–95 are injected (code 3). The '1988½' update changed the ride, the gearing and the transfer case drain plugs. Santana and Gypsy trucks use the same basic design, but many parts differ.

Spotting the real thing

Samurais are widely modified, and Santana, Maruti and Japanese versions share the basic design with many detail differences. Confirm what you're looking at.

Asked on every forum

Suzuki SJ / Samurai questions, answered

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

About a 215/75R15. On Zukiworld, owners say a 215/75R15 fits a stock Samurai with no modifications and 225s fit with a little effort. A 235/75R15 (about 29 inches) needs trimming and flattened inner fender seams, a 1.5–2 inch lift, or both. Stock tires were P205/70R15 according to the 1986 brochure.

SOURCE · ZUKIWORLD · 1986 BROCHURE
Does the Samurai really roll over easily?

It depends who you ask. CU's 1988 'Not Acceptable' rating came from tip-ups in a severe, modified avoidance maneuver, and NHTSA denied petitions to investigate a defect. In the 2004 settlement CU said it never meant the Samurai easily rolls over in routine driving. NHTSA's Michigan data put its rollover rate close to the Wrangler's, but it's still short and narrow, so drive it like one.

SOURCE · CU/SUZUKI JOINT STATEMENT · NHTSA
Which years should I buy?

1986–early 1988 trucks have the firmest ride and the tallest fifth gear (0.795). The '1988½' update brought softer springs, a thicker front anti-roll bar and a 0.865 fifth gear. 1990–95 trucks have throttle-body injection. Condition and the quality of past modifications matter more than the year.

SOURCE · MOTORTREND · 1986 BROCHURE
What engine does it have, and what's the common swap?

The 1,324 cc SOHC eight-valve G13A (64 hp), then the injected G13BA. The common upgrade is a 1.6-litre Sidekick or Tracker engine, which bolts to the same mounts. Trail Tough sells kits for 1.6 and 2.0/2.3 Suzuki conversions. Check your state's emissions rules first.

SOURCE · WIKIPEDIA · TRAIL TOUGH
Should I re-gear the transfer case or the axles?

Trail Tough's advice is to do both, in that order of importance: choose ring-and-pinion gears to suit the tire size, then pick transfer case gears for crawling. Doing all the reduction in the transfer case overloads the U-joints, the transfer case mounts and the frame brackets.

SOURCE · TRAIL TOUGH
How much lift do I need for 29s, 31s or bigger?

Trail Tough rates the 2-inch Old Man Emu spring kit as 'just right for a 29-inch tire'. Its spring-over kit gives about 4.5 inches of lift for up to 31-inch tires. Bigger than that usually means a body lift, longer shackles, or a Toyota axle swap with custom steering.

SOURCE · TRAIL TOUGH
Can I put Toyota axles under a Samurai?

Yes, and it's a very common swap. 1979–85 Toyota truck axles are about 5 inches wider than the Samurai's and take the same brake fittings. You need a way to deal with the different front spring perch width, flange adapters or redrilled flanges for the driveshafts, and aftermarket steering, because Samurai steering won't fit. Trail-Gear and Low Range Off-Road sell conversion kits.

SOURCE · ZUKIWORLD · TRAIL-GEAR
Why does it grind or vibrate in 4WD high when it's lifted?

According to Trail Tough, the transfer case tilts down 7 degrees at the back while the front pinion points up about 9 degrees, so the front driveshaft's U-joint angles work against each other. Lift makes it worse. Tipping the pinion won't fix it, though a CV front driveshaft helps.

SOURCE · TRAIL TOUGH
What fuel economy and tank range should I expect?

Suzuki's 1986 brochure quoted 27 mpg city and 29 highway (1986 EPA estimates) and a 40-litre (10.6 US gallon) tank. Real-world numbers fall with big tires and lift.

SOURCE · 1986 BROCHURE
What lockers fit?

Trail Tough's Spartan automatic locker fits the rear of every Samurai and the front of 1986–89 trucks. ARB Air Lockers and spools are also available. Even an open front diff with a rear locker makes a big difference on the trail.

SOURCE · TRAIL TOUGH
Are there any recalls?

NHTSA lists one US campaign: 95V103008 for 1988–1991 Samurais, which covers front seat belt buckles whose red release buttons can break.

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

Common modifications & who does them

SUSPENSION LIFTAn Old Man Emu spring-under kit adds about 2 inches for 29-inch tires. A spring-over (SPOA) conversion gives about 4.5 inches for 31s and is the classic Samurai trail build.
TRANSFER CASE GEARSLower transfer case gears are the Samurai's signature crawling mod. Sumo 4.16:1 gears give 84 percent more low-range reduction, and 6.4:1 gears give 181 percent. Brace the case mounts when you fit them.
AXLE GEARS & LOCKERSRegear the 6 7/8-inch Suzuki differentials for bigger tires, then lock them.
AXLE SWAPToyota axles are wider and stronger and have a deep aftermarket, which is why they're the standard upgrade for big tires.
ENGINE SWAPA 1.6 from a Sidekick or Tracker bolts to the same mounts. 2.0 and 2.3 conversions go further.
STEERINGKnuckle-over steering puts the drag link above the springs and cures bump steer on spring-over trucks.
ARMOR & BUMPERSSkid plates, sliders and tight-fitting bumpers protect a truck that spends its life on rocks.
