Fits: 2001 thru 2010 Chevy Silverado/GMC Sierra 2500HD/3500HD LB7/LLY/LBZ/LMM Duramax Diesel 

Cranking up the factory torsion bars and cogs overloads the adjusters and limits suspension travel, creating a harsher ride and accelerating front-end wear. Our system uses special re-indexed torsion-bar adjusting cogs that level the vehicle without compromising suspension performance and custom valved Fox shocks for the ultimate ride quality and front end wheel travel. With the kit installed, you can use up to 33" Diameter tires. Installation is straight forward and can be accomplished in less than two hours, excluding the required professional alignment.

• (2) Rear Fox 2.0 Performance Series IFP shocks Part# 980-24-664
