2020-2024 GM 2500HD/3500HD 6.6L L5P Duramax Torque Converters

The stock torque converter equipped on your 2020-2024 GM 6.6L Duramax is really only built for standard daily driving, so when you start adding on performance mods, it struggles to handle the increased levels of horsepower and torque. To ensure your truck can handle these elevated power levels, upgrading to a high-performance torque converter is necessary. Our premium torque converters are designed to manage much higher levels of power and torque, providing your GM 2500HD/3500HD with consistent transmission performance, even in demanding situations. Stay ahead of the curve and pair your new Torque Converter with a new Flex Plate to add even more reliability to your transmission.
