Zone Offroad ZONC39F/C39N 5.5" Lift Kit

To properly lift the Colorado/Canyon suspension 5.5", we started with ductile cast iron steering knuckles that reposition critical steering and control arm mounting locations, and work in harmony with the heavy-duty, fabricated crossmembers. Differential drop brackets lower and reposition the front differential for correct CV shaft angles and still allow for use of the factory front driveshaft with the help of a spacer that helps retain optimum CV joint positioning.

A full-width differential skid plate protects the relocated differential from the underside and ties the front and rear crossmembers together. Factory struts are retained and relocated with top spacers to gain a full 5.5" of lift without requiring any strut disassembly and that position the struts to eliminate binding through wheel travel. In the rear, a new block and U-bolt kit provided 4" of lift to level out the rear with the front. Extended sway bar links, bump stop extensions, and brake line relocation are also included.
