Detail About this part
What it is
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, rear 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. Featuring a 10-stage variable valving system, high-pressure nitrogen charge, and durable 54mm shock body with 18mm piston rod, these shocks are built for performance and longevity.
Room for Bigger Tires: Make room for aggressive wheel and tire combos. This 6" lift offers enough clearance to run up to a 37" tall tire with proper backspacing, giving your truck the rugged stance it deserves.
Improved Steering and Handling: To maintain proper drivability, a raised steering block is included correcting steering geometry for tight, responsive handling after the lift.
Limited Lifetime Warranty: Rough Country backs this kit with a Limited Lifetime Warranty, giving you long-term confidence on and off the road.
