These models share the same suspension concept with the 1988 to 1998 year model trucks, but none of the components are interchangeable. Superlift uses the same proven lift method. The factory upper and lower control arms are lowered in relation to the frame, which brings ride height up. By keeping the factory control arms and torsion bars, we are able to retain stock alignment geometry and ride quality. The front differential assembly is also lowered, via plate steel bracketry, to keep CV axle angles in check. Superlift’s new control arm brackets tie into crossmembers that span the distance between each frame rail along with optional "kicker" braces to form an exceptionally strong assembly. The vehicle steers through a centerlink. Bracketry lowers the factory centerlink to keep the tie rods in phase with the lower control arms. A greasable stabilizing link regulates centerlink movement and reduces the load and stress transmitted to the pitman and idler arms. Superlift's lift method does not increase front track width or require the front differential housing to be trimmed, as is the case with most replacement knuckle systems.

Note that on pickups, front lift height can range from 6" to 7.5". Front vehicle height is determined by torsion bar adjustment; you choose rear lift height and method. The Tahoe / Yukon / Avalanche rear lift is set at 6" via new rear coil springs.
