Application: 1997-2003 Ford F-150 All Cabs, 1997-2003 Ford Harley, 199-2004 Ford Lightning. Note: Used in #6419 Shackle/Hanger Kit. Includes: Front leaf spring hangers, Hardware, bumpstops. driveline angle corrections, installation instructions. Belltech Hanger Kits are designed to minimally lower the rear of your leaf spring equipped Sport Truck or SUV by 2-4? (*application dependent). Belltech?s redesigned Hangers reposition the front 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.
