ReadyLIFT® 3/2" lift kit for 2020-2022 Chevy Silverado and GMC Sierra 2500/3500 HD trucks including the popular AT4 package. 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 is specifically designed to function and install properly on this new suspension design, providing 3" of bolt-on lift that comfortably allows for 35" tires.
For those who want a lifted stance all the way around on their new 2020-2022 GM HD truck, the 69-3030 3"/2" SST lift kit system provides 3" of adjustable front lift with new forged torsion keys specialized for this 3" front lift. Taller differential drop spacers and skid plate spacers are included, as well as new taller bump stops, rear shock extensions and OE style cast iron 2" tall rear lift blocks with new longer U-bolts. The 69-3030 SST lift kit works with trucks equipped with either the OE #84461807 or OE #84634344 factory torsion keys and requires ReadyLIFT torsion key unloading tool 66-7822B or KRP0137 or similar for installation.
Can be used on trucks equipped with factory snow prep/plow packages.
