Special Note: When setting the torsion key adjustment bolt do not exceed 26 from the wheel center to the fender edge. Exceeding this will overlift the vehicle creating a top off condition, meaning the suspension has little to no down travel. The result is poor ride quality and premature wear of components. ReadyLIFT offers a heavy duty adjustable leveling kit for the all new 2020 2024 Chevy Silverado and GMC Sierra 2500 3500 HD trucks.

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.
