PRODUCT OVERVIEW: - 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.
