2019-2024 GMC 1500 6" Big Lift Kit (44-3960)

Fits

Almost 1 year of engineering and development has gone into this 6" Big Lift Kit from ReadyLift. Featuring HD angled and offset top mount strut extensions that realign the struts to optimize shock performance and minimize wear. A specially designed lower mount strut pre-load spacer offers the added benefit of a slight increase in spring rate to better handle larger wheels and tires. Integrated bump stop landings and rear shock extensions allow you to retain full operation of the factory equipped ARC system, effectively providing you with improved ground clearance, incredible articulation, and predictability for one amazing off-road ride over any terrain.
