Description Features and Benefits

RL 3.0'' SST LIFT KIT- CHEVY/GM 3"F / 2"R SST Lift Kit- GM Silverado / Sierra 2500HD 2020-2021 ReadyLIFT is thrilled to introduce a heavy-duty suspension lift option for 2020-2022 Chevy Silverado and GMC Sierra 2500/3500 HD trucks, including the AT4 package. General Motors' updates to the torsion bar suspension necessitated the engineering of a new SST lift kit by ReadyLIFT, tailored for this redesigned suspension. This innovative 3" SST lift kit system accommodates 35" tires comfortably. Specifically, for those seeking an all-around lift for their 2020-2021 GM HD truck, the 69-3030 3"/2" SST Lift Kit is offered. It delivers 3" of adjustable front lift through specialized forged torsion keys, distinct from those in the 66-3020 kit. The kit includes taller differential drop spacers, skid plate spacers, extended bump stops, rear shock extensions, and OE style cast iron 2" tall rear lift blocks with longer U-bolts. It is compatible with trucks equipped with either OE #84461807 or OE #84634344 factory torsion keys and necessitates the use of ReadyLIFT torsion key unloading tool 66-7822B or equivalent for installation. Additionally, it can be used on trucks with factory snow prep/plow packages. The ReadyLIFT 2020 GM HD SST Lift Kits are chosen for their ability to maintain the factory ride and handling. They boast industry-leading forged torsion keys with specific indexing for each application. These kits provide clearance for larger aftermarket tires, up to 35", and include CNC machined billet Aluminum differential drop spacers with extended hardware to ensure proper CV angles and driveline geometry. The factory skid plate remains usable thanks to new skid plate spacers. Each SST lift kit includes 2" tall OE style cast iron tapered rear lift blocks and heavy-duty rear shock extensions to eliminate the need for purchasing new rear shocks. To correctly limit suspension compression, the kit comes with four taller bump stops. Importantly, every kit includes the ReadyGuard Powertrain Warranty. 20202022 GM 2500/3500 HD including AT4 3" Front/ 2" Rear SST Lift Kit SST lift specific Forged Torsion Keys Front/rear shock extensions Differential spacers New longer bump stops 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 202020202022 GM 2500/3500 HD including AT4 Allows for 20x9 0 offset Allows for 20x9 0 offset 35x12.50 tire Max with trimming: 20x10 Max with trimming: 20x10 18 offset 35x12.50
