Leveraging one of our top-selling application designs for the AT4 and TrailBoss 1500 trucks, our engineers adapted the quality and features into the all-new AT4X and ZR2.  Forget squeaks, rattles, and vibrations; these lift kits ensure superior performance with smooth rides over all terrain. Designed to provide more ground clearance and increased flexibility on the street or trail, the big lift kits utilize boxed steel front/rear cross members and a full-width front skid plate constructed of thick 3/16" plate steel. New 1/4-inch boxed plate steel differential drop brackets feature a double gusset and boxed center rib to take the abuse of front differential torsional twisting on the big kits.Our Big lift kits feature heavy-duty 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 manage unsprung mass resulting from the larger wheels and tires finding their way onto this newly lifted truck. To lift the rear, new fabricated steel rear blocks with integrated bump stop landings are added as well as new rear shock extensions to retain the factory performance shocks.With thousands of engineering and development hours and more awesome features than we could possibly mention, these are the best lift kits available on 2025 GM 1500 ZR2/ZT4X trucks!
