Quick Overview

The Superlift 4" & 6" lift kit for the Chevy, GMC pickup, Blazer and Suburban is still known as the GM systems to have. Lowering the factory upper and lower control arms in relation to the frame brings ride height up. By keeping the factory control arms and torsion bars, you retain stock alignment geometry and ride quality. Front track width is not increased.

Full-width differential control arm crossmembers provide lateral rigidity. Crossmember kicker braces add strength. No trimming of front differential housing. Dropped centerlink restores proper steering linkage geometry. Centerlink stabilizing links make steering more responsive and extends life of pitman / idler arm. Steel skid plate protects front differential.
