Symptoms
Sagging front end, uneven side-to-side height, or room needed for bigger tires.
The fix, step by step
- Measure both sides from hub center to fender lip.
- Turn the torsion-bar adjuster bolts evenly, a little at a time, and settle the suspension between measurements.
- Edmunds owners note that adjusting one side changes the other, and that the bars may need re-indexing if you run out of adjustment.
- Don't crank the bars for lift: a higher, stiffer front end makes this tall truck tippier.
- For real height, Pedders sells a kit of about 50 mm with new torsion bars, coils and shocks; the Gen 2 has two bar lengths, so check yours.
- Get an alignment afterwards.
