ReadyLIFT delivers a performance game changer for the popular 2020-2024 Chevy Silverado and GMC Sierra 2500/3500 HD truck with the release of ReadyLIFT's 69-30320 3-inch lift kit including Falcon 1.1 Monotube shocks. Designed to improve stance, performance, and capability, this kit includes everything necessary to clear up to 35" tires. This kit features ReadyLIFT's Falcon 1.1 Monotubes shocks designed specifically for the GM 2500/3500 to bolt on for performance that increases travel and the ability to navigate rough terrain and smooth out on-road comfort.


This 69-30320 system provides a 3" front lift with forged torsion keys coupled with re-engineered heavy-duty fabricated 4130 chromoly steel upper control arms including all-new heavy-duty high angel ball joints and maintenance-free TCT non-bonded pivot bushings. In the rear, ReadyLIFT provides lift blocks for a lifted, level stance that retains factory load capacity, while all four corners of the truck receive Falcon 1.1 Monotube shocks to deliver the best-lifted ride quality available.

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.

Please read Instructions thoroughly and completely before beginning installation. Installation by a certified mechanic is recommended.

Estimated Installation Time: 5.5 Hours +/- 1 hour (excluding alignment and wheel/tire assembly)
