ReadyLIFT Premium 3.5” SST Lift Kit for 2020 GM HD

ReadyLIFT has responded to GM’s changes to the torsion bar suspension of their 2020 HD pickups. The 69-3035 adjustable forged torsion key SST lift kit was specially designed to install and function properly on this new suspension.

Providing 3”–3.5” of front lift, it includes all-new fabricated-steel Xtreme-Duty upper control arms that use ReadyLIFT’s popular “winged” design and four new 5100 Bilstein shocks for a performance-tuned ride and handling.
