Fabtech suspension lift kit.
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 Fabtech’s 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. They are arched at the bottom to provide ground clearance and have a skid plate to protect the front differential against offroad obstacles. 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.
A suspension lift raises ride height to clear larger tires; component kits vary in what they include, so check the parts list.
