We received so much positive feedback and demand to add the Detroit DD13/OM471 application to our lineup, that we put our engineering and manufacturing teams to work to add this essential on-highway engine line. IPD is excited to offer a reliable and cost-effective product line to extend the engine life and performance of your trucks. IPD’s engine rebuild kit for Detroit DD13/OM471 is made entirely from new, quality parts. IPD’s engine components begin with drawings by our inhouse engineering team, who reverse engineer the specifications to ensure a perfect fit every time. Engine components are tested and approved by our in-house quality assurance team and our company and processes are ISO 9001: 2015 certified.
