Description

Upgrade your GM C10 with these heavy-duty 2.5" drop spindles featuring a UMI satin black powder coat for ultimate durability and an enhanced aesthetic appeal. These robust spindles are engineered to be a direct bolt-in replacement, seamlessly accepting factory GM C10 bearings and brakes, making installation straightforward and hassle-free. However, it's important to note that if your brake rotors are 1", some hot rodding will be required. Designed specifically for the 1973-1980 GM C10 trucks, these spindles fit perfectly with 1-1/4" brake rotors. If you own a 1981-1987 model, you might find that it comes with 1" brake rotors. In such cases, you'll need to upgrade to the 1-1/4" rotors used on the earlier models to ensure compatibility and optimal performance.
