Transform your truck's stance and capability
Upgrade your GM truck from front to back with Rough Country's 4" 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 and brake line brackets maintain proper geometry, ensuring a smooth, factory-like ride after installation. For a complete suspension upgrade, the kit is also available with replacement rear lifted leaf springs, offering consistent rear lift and eliminating the need for lift blocks.
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 4" lift offers enough clearance to run up to a 35" tall tire with proper backspacing, giving your truck the rugged stance it deserves.
Improved steering and handling
To maintain proper drivability, a raised steering arm is included correcting steering geometry for tight, responsive handling after the lift.
Limited lifetime warranty
