69-30350 - GM Silverado/Sierra 2500/3500 HD 2WD/4WD 3.5" SST Lift Kit - 2020-2022
For those who want a more lifted stance than what our popular 66-3020 2" leveling kit or 69-3030 3" SST lift kit, we now offer the 69-30350 3.5"/2" premium SST Lift Kit. This system provides 3.5" of adjustable front lift with new forged torsion keys specialized for this 3.5" front lift.

Taller differential drop spacers and skid plate spacers are included, as well as new taller bump stops round out the front suspension. Our popular OE style cast iron 2" tall rear lift blocks with new longer U-bolts provide the right rear lift for a strong stance. And to make it all ride and handle to match the truck's lifted look, we include new front/rear Falcon 1.1 Monotube series shocks. The 69-30350 SST lift kit works with trucks equipped with either of the OE #84461807 or OE #84634344 factory torsion keys, and requires ReadyLIFT torsion key unloading tool 66-7822B (or similar) for installation.

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.
