Description
Forged 4140 steel replacement torsion keys index the factory torsion bars for 1-3 in. of adjustable front lift, and the included shock extenders keep the front shocks within their working range.
Fits: 2001-2010 Chevrolet Silverado/GMC Sierra 2500HD and 3500HD 8-lug torsion-bar trucks, 2WD or 4WD, including LB7, LLY, LBZ and LMM Duramax trucks.
What's Included
- 2 forged torsion keys
- 2 front shock extenders
Important Notes
- A torsion-bar unloading tool is required.
- Body Armor notes: if 1/2 in. to 1 in. of adjuster-bolt thread is already exposed on the factory keys, the desired lift may be achievable with the factory keys plus the shock extenders, because the Body Armor keys may be indexed too far for that truck.
- Rated for tires up to 33 in.
- Alignment check and headlight re-aim are required after any torsion-bar adjustment.
