ACDelco proudly offers over 90,000 high-quality auto parts in 37 product lines. Each product classification has its own benefits, and each has been engineered and tested to meet ACDelco’s high standards. Our GM Original Equipment auto parts are the guaranteed original part for GM vehicles that meets or exceeds OE specifications. ACDelco Professional aftermarket parts and products cover most GM vehicles as well as many other makes and models. ACDelco Advantage products offer fit, form and function for most makes and models at a more affordable price. For some auto parts, we also offer a Specialty line. These products are designed to meet a specific need for a narrow audience, such as our Performance brakes and brake products, which are rotors and friction designed for police vehicles.
