2019-2024 GMC/ Chevrolet 1500 AT4, Trail Boss 


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.

Part Number: 44-39420
