*Belltech Drop 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. *Belltech Drop Ball Joints* When GM introduced the successor to the wildly successful S-series platform, Belltech was the first on the scene. With the latest design techniques, our engineers developed what this platform needed, the Belltech Drop Ball Joint. Belltech offers the only 2 inch lowering Drop Ball Joint for all 2WD Colorado/Canyons. Using the same ideology as the industry standard Belltech Drop Spindle, Belltechs lowering Drop Ball Joint replaces the stock lower ball joint and relocates the upper ball joint position. The design allows the vehicle to retain the use of stock wheels without any clearance issues while providing the lowering needed. As you have come to expect from any Belltech product, factory suspension & steering geometry along with ride comfort is retained.
