Product Details
The ReadyLift 6" Big Lift Kit w/Falcon 2.1 Shocks 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. To lift the rear, new fabricated steel rear blocks with integrated bump stop landings have been added as well as new rear Falcon 2.1 Monotube shocks.
