2019-2024 GMC 1500 4" Lift Kit (44-39420)

Fits

Ask and ReadyLift will deliver; this front lift kit includes a longer front shock/strut assembly. When combining a traditional leveling kit on these factory lifted trucks, several issues present themselves including binding problems with the factory control arm ball joint and contact concerns with the lower strut/CV axle assembly. This kit provides the required amount of lift without causing conflict with the factory strut geometry and clearances.
