ReadyLIFT® is excited to announce that we now offer two new heavy-duty suspension lift options for the all-new 2020-2021 Chevy Silverado and GMC Sierra 2500/3500 HD trucks. 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 new leveling and SST lift kits that are 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 and a new 3"" SST lift kit system, both of which comfortably allow for 35"" tires. 66-3020 - Adjustable Leveling Kit - GM Silverado/Sierra 2500/3500 HD 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 66-7816A or similar for installation.
