ReadyLIFT® now offers three new suspension lift options for the all-new 2020 Chevy Silverado and GMC Sierra 2500/3500 HD trucks. Along with outward appearance changes to the new GM HD, changes were also made to the long-standing torsion bar suspension. The changes required ReadyLIFT to engineer new leveling and SST lift kits that function and install properly on this new suspension design. Our dedication to professional engineering and manufacturing has created 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.
