2007.5-2010 LMM DURAMAX | COOLER UPGRADE KIT W/UP-PIPE

Factory cooler setups recirculate soot and harmful gasses through your engine causing build-up and clogs, resulting in loss of performance and proven mechanical issues. GDP Cooler Upgrade Kits remove those concerns from the equation. GDP components install with an exact fit resulting in a longer lasting & better running truck, less turbo lag for better throttle response, cooler engine temps, less weight and a cleaner looking engine bay. Proudly Made in the USA.
