Product Details

The ReadyLift 6"+2" Big Lift Kit is made for the 2025-2026 Chevrolet Silverado 1500 Trail Boss, giving it more ground clearance and room for larger tires.

The lift kit utilizes the very best in ReadyLIFT engineering with 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.Our 6" (6" + 2") lift kit features 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 handle the larger wheels and tires that will find their way onto this new lifted truck.
