2019-23 4WD Chevy Silverado, GMC Sierra 1500 6" spacer UCA lift kit, Nitro shocks

The 6” Zone Offroad suspension lift kit for the Silverado and Sierra 1500 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. Pair all this with the replacement upper control arms to 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’s 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 5” lift block with longer u-bolts for a level stance.

Stock 17" and 18" wheels cannot be reinstalled due to tie rod end interference, stock 20" wheels can be reinstalled.
17" Wheels with 4.5" backspacing should be test fit prior to mounting the tire to ensure proper clearance to the steering knuckle / tie rod.
All aftermarket wheels should be test fit prior to mounting the tire to ensure proper clearance to the brake caliper. Some wheel profiles will not clear the brake caliper. These can be test fitted before the vehicle is lifted in a stock condition.
