ReadyLIFT offers a heavy-duty adjustable leveling kit for the all-new 2020-2021 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 leveling that is specifically designed to function and install properly on this new suspension design. Our dedication to professional engineering and manufacturing has yielded a new adjustable forged torsion key leveling kit system that provides a comfortable ride and allow for 35" tires. The 66-3020 Adjustable Leveling Kit includes our industry-leading forged torsion keys that feature new indexing specific to the new 2020-2021 GM HD platform. This kit also includes front shock extensions, differential drop spacers and factory skid plate spacers. Leveling lift is in the range of 2", but the amount of actual lift required will depend on the vehicle. This kit includes differential drop spacers to help maintain factory geometry and corrects CV axle angles. 66-3020 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 similar for installation. Why Choose ReadyLIFT 2020 GM HD Leveling Kits? Maintains the factory ride and handling. Features industry-leading forged torsion keys with specific indexing designed for each application. Delivers clearance for increased aftermarket tire sizes - up to 35'' Kits include important CNC machined billet Aluminum differential drop spacers with longer hardware to ensure correct CV angles and drive line geometry. Maintains use of the factory skid plate via new skid plate spacers. Every kit includes ReadyGuard Powertrain Warranty.
