Eliminate the risk of factory transmission line failure with the Fleece Performance high-flow cooler line kit. Designed specifically for 2006-2010 GM Duramax 6.6L trucks equipped with the Allison transmission, these lines are engineered to handle increased pressure and heat better than stock components. Whether you are towing heavy loads or pushing your Duramax for performance, these lines provide the reliability you need.
Factory lines are notorious for leaking at the crimp points; this kit replaces those failure-prone sections with robust, high-performance alternatives. Ensure your Allison transmission stays cool and protected under all driving conditions. Trust the experts at GGCRACING to provide the premium components your truck deserves.
