This levelling kit provides the required amount of level lift without causing compromises to the factory strut geometry and clearances with our new interlocking pre-load spacer for ease of installation. Considering the factory upper control arm's limited dynamic range when the AT4X/ZR2 truck is further lifted, this levelling kit includes our popular tubular upper control arms with corrected ball joint cup angles, heavy-duty replaceable ball joints, and our new Terrain Control Technology (TCT) maintenance-free pivot bushings with side-biter washers to improve alignment retention

Features interlocking ‘puzzle-type’ pre-load spacer for easy installation.
Includes DOM tube steel upper control arms with TCT maintenance-free pivot bushings.
Retains factory turning radius.
NOTE: Use of Auto 4 Hi feature not recommended.

NOTE: AT4X and ZR2 may not fit the same size tire. This is due to the difference in the front fender opening design.
Tire 33x11.50 on 20x9 0 offset wheel
Max tire with trimming 295/60-20, 20x9 0 offset wheel

Tire Size Note:
ReadyLIFT wheel and tire fitment recommendations are typically based on Wheel Pros wheels and Nitto tires. Due to product differences among tire manufacturers, tire specifications and dimensions including, but limited to, overall diameter, rolling diameter, tread width, aspect ratio, lug pattern, sidewall construction and inflation pressure, will vary meaningfully by tire and wheel manufacturer.
Every tire and wheel combination should be test fit prior to installation.
Consult your local installer to learn more about the right tire fitment for your application.

Ride Quality Note:
When lifting a vehicle and installing aftermarket wheels and tires, a tire manufacturer's construction and material quality can alter vehicle ride quality. When increasing a vehicle wheel and tire size, most larger aftermarket truck and SUV tires are 10-ply (or more) E tires compared to typical OEM 6-ply C tires. This more rigid sidewall construction increases the perception of suspension stiffness often described as ride harshness. The ride, handling, traction, noise, fuel economy, and wear differences between All-Season, All-Terrain, Mud-Terrain, or Trail-Terrain type tires can be significant. Please take into account tire and wheel choice will generally have a meaningful impact on the ride & handling experience.
