GMC Sierra 1500 Suspension Lift Kit - Rear - Fabtech - 1.5 in. Lift - 99-06 is a rear leaf spring block kit designed for 2WD GM C1500 models with 6-lug wheels from 1999 through 2006. This Fabtech FTSBK15 block provides a straightforward 1.5-inch rear lift to adjust rear ride height and accommodate light changes in load or tire size.
Built as a direct-fit replacement rear block, this kit is targeted at the budget-minded enthusiast who wants a simple, reliable way to raise the rear of the truck. The kit is made to fit the factory leaf spring configuration and uses the existing suspension mounts. Installation is typically accomplished with common shop tools and basic mechanical experience. This is a practical option when looking to correct rake, gain modest height, or support mild changes in rear-end geometry without modifying other suspension components.
