Superlift is setting a new standard for value with its new offering for the 99-06 Chevy/GMC 1500 4WD Pickups and SUV’s. All fabricated components of this kit were designed, manufactured and packaged right here in the USA. You won’t find quality craftsmanship like this anywhere else or anywhere near this unbelievable price point.

This kit is packaged complete with everything you need to do the job right, requires less differential and frame modification than most competitor kits and eliminates the need for a replacement front driveshaft. It includes one-piece, laser cut, CNC formed, high-clearance crossmembers, a protective front skid plate, axle relocation brackets, front axle CV spacers, torsion bar relocation brackets, extended sway bar links and Superlift Superide shocks. The included cast ductile iron steering knuckles simplify installation and yield the best in class alignments results. Rear lift is achieved via tried and true 5” cast iron blocks to provide a nice level stance front to rear.

Packaged standard with the Superlift Superide shocks we also offer upgrade Superlift Superide SS shocks by Bilstein. An optional steering stabilizer is also available.
