This Superlift 6" Knuckle Version lift kit for the Silverado, Sierra, Avalanche, Suburban and Yukon XL includes replacement steering knuckles with minimal increase in track width. The high-clearance lower control arm one-piece crossmembers are constructed using 1/4" steel plate. This is further reinforced by kicker braces. A skid plate is included to protect the front differential. Superlift designed this lift so the factory upper control arms remain in their original location. The factory lower control arms and axle housing are lowered in relation to the frame. Exception drivability is achieved with the Superlift geometry - from steering timing and linkage angles to driveshaft and CV axle operating angles.
