2019-2021 GMC 1500 6" Big Lift Kit (44-39610)

Fits

 With over 9 months of engineering and development from ReadyLift and more awesome features than we could mention, the bottom line is this Big Lift Kit is one of the strongest, safest, and easiest lifts you can install on your 1500. It features 1/4" boxed plate steel differential drop brackets with a double gusset and boxed center rib to take the abuse of front differential torsional twisting & HD angled and offset top mount strut extensions that realign the struts to optimize shock performance and minimize wear.
