Hughes XFM Series Diesel Torque Converters provide super-duty performance and are made for the Ford Powerstroke, the Dodge Cummins and the GM Duramax. Hughes XFM Series Diesel Torque Converters are built to take all the punishment these modern diesel engines can create by using billet steel covers that cannot flex or distort even under the most challenging situations. Instead of trying to "lockup" the converter for increased efficiency and fuel mileage with any type of single disc, Hughes XFM Series Diesel Torque Converters have a triple-disc design. This triple-disc design significantly increases the torque converter's ability to endure the increase in torque and power. Made in the U.S.A.
