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. The heart of this lift kit is Fabtechs cutting edge RTS design. The RTS is a bracket system that keeps the torsion bars in the factory location while providing lift. This feature provides superior ground clearance at the frame as there are no torsion bars hanging down to become high centered on or damaged when offroading. It provides a very clean appearance to the vehicle. Another important aspect of this GM 3500HD lift kit is the lower control arm crossmembers.

The crossmembers and bracketry are built with 1/4" thick steel that provides strength and rigidity to the vehicles suspension. The superior build quality and design of the components allows for a fast installation time with only four holes to drill and no cutting of the front diff housing.
