Belltech Shackle and Hanger Kits are designed to lower the rear of your leaf spring equipped Sport Truck or SUV by up to 5" (*application dependent). Belltech's redesigned Shackle and Hangers reposition the front and/or rear leaf spring mounting points (spring eyes) so you can simply and effectively lower your leaf spring equipped Sport Truck or SUV without modifying or changing the factory leaf spring. This allows you to retain OEM ride quality and more importantly factory load capacity.
