Belltech 3100 3 Inch Drop Spindle Set, 1973-87 GM Truck HD Rotor

In 1983, Belltech developed one of the industry's first revolutionary products to help jump start the Sport Truck craze, the Drop Spindle.

By relocating the spindle pin (or hub) higher on the spindle casting, our engineers can provide a 2-3" drop without negatively affecting front end suspension or steering geometry, not even the shock absorber!

Belltech Drop Spindles offer various drop amounts depending on your 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 crafted from powdercoated, CNC machined, high strength ductile iron castings providing the structural integrity to meet and exceed all factory specifications & requirements.
