Detroit® Genuine Parts

With Detroit® Genuine Parts, you know you’re getting a new or remanufactured part that fits your exact engine, axles or transmission. Because Detroit® Genuine Parts are made specifically for your Detroit® product, there is no “making it fit” or “this will do.” Detroit gets it right every time.

Your new or remanufactured part was engineered for performance, durability and reliability. It was built by the same Detroit® team that built your original engine, transmission and axles. Get everything you expect from the experts at Detroit® with Detroit® Genuine Parts. Before new and remanufactured parts are branded with the Detroit® Genuine Parts logo, they are put through the most rigorous examination and testing processes in the industry. Every Detroit® Genuine Part is backed with a 1-year/unlimited-mile Detroit warranty. If you ever experience problems or need help, we have over 700 authorized service centers located across North America.

At Detroit®, we’ve streamlined the way we deliver products throughout our extensive dealer network. Our parts distribution centers are strategically positioned and inventoried to serve customers as efficiently as possible. Detroit® has a retail management system to make sure that parts are readily available throughout our dealer network.
