This high quality 6" lift kit for the GMC Sierra and Chevy Silverado 3500HD has been designed to improve the offroad capability of the vehicle while providing a smooth highway ride. The Fabtech lift kit retains the factory load carrying capacity of the vehicle that is perfect for owners that use their truck for towing and hauling.
