4 Inch Lift Kit Chevrolet, GMC K20, K25 Truck, Half-Ton Suburban (77-91)

Give your truck an impressive upgrade, front to back with Rough Country’s 4" GM Suspension Lift Kit! This easy-to-install lift kit raises the front of your vehicle to be equal height with the rear for a leveled, better-than-stock look that gives an improved ride height and more aggressive appearance.

This kit features a set of front lifted leaf springs allowing you gain additional ride height without sacrificing ride quality or performance. A set of rear blocks and brake line brackets are provided to keep everything at optimum angles for a factory-like ride, even after lifting.

A set of Rough Country's premium N3 shocks are also included. These fine tuned 10-stage variable high-pressure Nitrogen charged shocks offer a fantastic blend of off-road action and smooth highway ride quality. With a durable 18mm spring-loaded piston rod and faster-cooling 54mm shock body.
