Quick Overview

The Zone 6" lift kit for the Chevy Silverado and GMC Sierra was designed to perform. The main crossmembers constructed of 1/4" thick steel were designed to match the factory geometry with the new Zone CNC machined steering knuckles creating a true factory quality driving experience. Match this geometry with the heavy duty differential skid plate that locks the main crossmembers together and the compression struts that tie back to the frame and you have a system ready for some serious abuse! The 3-point differential mounting system correctly positions the differential so the factory driveshaft can be used. Also included are 4 Nitro shocks. Shock boots sold separately.
