3'' SST Lift Kit - GM Silverado / Sierra 2500HD/3500HD 2020-2024

ReadyLIFT has updated the popular 3” lift to fit the 2023-2024 GM HD 2500/3500 trucks. The new 69-30300 is designed for the 2020-2024 Chevy Silverado and GMC Sierra 2500/3500 HD trucks with torsion keys up front, rear blocks, and our new front inner fender brackets to clear larger tires than before.   Designed to improve stance, performance, and capability, this kit includes everything necessary to clear up to 35" tires.

Along with the outward appearance changes to the new GM HD, General Motors also made changes to the long-standing torsion bar suspension. These changes required ReadyLIFT to engineer a new SST lift kit that are specifically designed to function and install properly on this new suspension design. Our dedication to professional engineering and manufacturing has yielded a new 3" SST lift kit system that comfortably allows for 35" tires. For those who want a lifted stance all the way around on their new 2020-2024 GM HD truck, we offer the 69-30300 3"/1" SST Lift Kit

Features and Benefits:

·         3" Front/ 1" Rear SST Lift Kit

·         Fits 2020-2024 MY GM HD 2500/3500

·         SST lift-specific Forged Torsion Keys

·         Front inner fender bracket to fit larger tires

·         Allows for no-trim 20x9 0 offset on a 35x12.50 tire.

·         *Max with trimming: 20x10 -18 offset - 35x12.50.  Some fender well trim variances may be experienced between Silverado and Sierra models.

Special Note:  When setting the torsion key adjustment bolt do not exceed 27” 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.

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. Max width on stock wheels is 11.5". 

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.
