The 4" Zone Offroad suspension lift kit for the Sierra 1500 Adaptive Ride control model trucks is designed to improve offroad performance, without sacrificing handling and a comfortable street ride. At the heart of this lift kit are steel crossmembers that re-position the factory lower control arms to provide additional ground clearance. Paired with the included differential skid plate, this creates a strong subframe that adds protection for critical driveline and steering components. Replacement upper control arms achieve improved strength and durability. Specially designed steering knuckles maintain the correct steering geometry for ESC compatibility. This knuckle design also will allow 17" or larger wheels, unlike most other lift kits. The chassis is further strengthened with heavy duty tie rod ends and a crossmember plate that is welded in. Multipoint differential relocation brackets secure the differential in its new location to keep the CV axle operating angles at a minimum. Front, top mounted steel strut spacers install without disassembly of the factory strut. The rear factory block is replaced with a 3" lift block with longer u-bolts for a level stance.
