DHD Duramax Manual Belt Tensioner Package 2002-2016 6.6L

As peak horsepower and engine RPM's continue to climb, it's becoming more evident that the factory Duramax belt tensioner is not sufficient! DHD's manual tensioner package is a complete solution to eliminating belt slip and belt deflection under high rpm and high load. This two-piece kit eliminates the factory spring driven tensioner that comes on your truck and adds an addition pulley to the routing system to increase belt engagement. This kit is a must for dual fueler trucks or those exceeding 4000rpm.

If a full mechanical tensioner is overboard for your engine, consider using our stand alone add-on pulley kit (DHD 800-155). Our add-on pulley kit bridges the large gap in belt routing and increases belt traction around the crank pulley.
