These spindles will increase the track width of your vehicle by approximately .45" per side. These were developed to allow the fitment of small diameter wheels (15" - 16") that were popular at the time of inception. Please make sure you are aware of this increase in track width before you purchase these lowering spindles., Since 1983 Belltech engineers developed one of the industry firsts that enabled the Sport Truck craze, the Belltech Drop Spindle. By relocating the wheel mounting point a.k.a. spindle pin higher on the spindle casting, our engineers were able to provide a 2-3” lowering without affecting any other suspension or steering geometry, not even the shock absorber! Belltech Drop Spindles offer a 2 or 3 inch drop depending on the application, while improving handling and retaining factory ride quality. Belltech spindles maintain critical suspension geometry and eliminate excessive ball joint, shock and tire wear common to other methods of lowering. Each spindle is built from OEM grade high strength ductile iron, providing the structural integrity to meet and exceed all factory specifications & requirements.
