When purchasing a Silverado/Sierra 3500/3500HD lift kit don't trust your truck to anything less than a Tuff Country EZ-Ride Suspension lift kit. More than your average lift kit, all systems are engineered to give the highest quality and best value on the market.

Tuff Country EZ-Ride Suspension's new Strong 3500/3500HD lift kits use new extended steering knuckles and a three-piece sub frame that includes two cross members that are connected by a heavy duty skid plate. This skid plate is designed to protect the front differential and stabilize the cross members for unmatched strength and durability.

This design also allows for an easier and quicker installation. 2 inch cast iron blocks lift the rear to level the Silverado/Sierra 3500/3500HD. Differential drop brackets and torsion bar drop brackets keep everything in alignment. Tuff Country has been producing quality suspension products for over 25 years and backs all lift kits with a limited lifetime warranty.
