OVERVIEW

Transform Your Truck's Stance and Capability: Upgrade your GM truck from front to back with Rough Country's 6" Suspension Lift Kit. This premium lift delivers a leveled, aggressive look while enhancing ride height and off-road readiness all with an easy bolt-on installation. Engineered for Superior Ride Quality: This kit includes application-specific front lifted leaf springs, delivering increased ground clearance without sacrificing ride comfort or control. Rear lift blocks, add-a-leaf springs, and brake line brackets maintain proper geometry, ensuring a smooth, factory-like ride after installation. Enhanced Performance with N3 Series Shocks: Rough Country's N3 series shocks come standard valved for your exact application and designed to provide a perfect balance of on-road smoothness and off-road capability.

Improved Steering and Handling: To maintain proper drivability, a raised steering arm is included correcting steering geometry for tight, responsive handling after the lift.
