A industry first and patented design, Belltech?s drop ball joint uses the drop spindle concept to easily and effectively achieve a full 2? drop. By relocating the mounting point of the lower ball joint, our engineers were able to provide a 2? lowering without affecting suspension or steering geometry, not even the shock absorber! Belltech Drop Ball Joints offer improved handling and retain factory ride quality. Belltech Ball Joints help maintain critical suspension geometry and eliminate excessive wear and tear common to other methods of lowering. Each Ball Joint is built from (Powedercoated) OEM grade high strength ductile iron, providing the structural integrity to meet and exceed all factory specifications & requirements. Fits: 97-03 Ford F150 (All Cabs) 2wd only, 97-03 Ford Harley, 99-04 Ford Lightning, 97-02 Ford Expedition/Navigator (2wd only). 2? Drop Spindle. 18? wheels or larger only. Direct bolt-on.
