When your Cadillac was put together, the factory used a specific set of parts, mandated and approved by Cadillac, to make the wonderful machine you drive today. It only makes sense that you would want those same kinds of parts when you get something replaced in your car, and that’s what we provide. OEM parts are the very parts that Cadillac designated to go into your car when it was assembled, and as such, are the very height of performance and power when they’re in your car.
