QUICK OVERVIEW
2020-2022 GM 2500/3500 HD including AT4
3" Front/ 2" Rear SST Lift Kit
SST lift specific Forged Torsion Keys with front/rear shock extensions, differential spacers, new longer bump stops and longer hardware.
Allows for 20x9 0 offset - 35x12.50 tire.
*Max with trimming: 20x10 -18 offset - 35x12.50 Some fender well variance may be experienced between Silverado and Sierra models. Can be used on trucks equipped with factory snow prep/plow packages. Works with trucks equipped with either the OE #84461807 or OE #84634344 factory torsion keys and requires ReadyLIFT torsion key unloading tool 66-7822B or similar for installation. NOTE: Use of Auto 4 Hi feature not recommended.
Special Note: When setting the torsion key adjustment bolt do not exceed 27.5” from the wheel center to the fender edge. Exceeding this will create a top off condition, meaning the suspension has little to no down travel. The result is poor ride quality, and premature wear of components.
TIRE FITMENT
20x9 0 offset - 35x12.50 tire.
*Max with trimming: 20x10 -18 offset - 35x12.50
Note: Silverado and Sierra have different fender well opening sizes - some minor trimming my be required depending on true tire size and design.
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.
