ReadyLIFT offers a heavy-duty adjustable leveling kit for the all-newChevy 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 a new leveling solution 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 allows for 35″ tires.
The 66-30200 Adjustable Leveling Kit includes our industry-leading forged torsion keys that feature new indexing specific to the new 2020-2025 GM HD platform. The leveling lift is in the range of 2″, but the amount of actual lift required will depend on the vehicle. 66-30200 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 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.
