This Heavy duty belt tensioner is manufactured by one of the largest original equipment tensioner suppliers to insure proper fit and performance. This tensioner is produced for serpentine belt routing applications and is made of high strength steel for improved life and durability. The tensioner maintains the O.E. round spring technology as well as the internal damping design specified for this application. This higher damping consequently reduces arm motion and wear as well as an optimized install feature for ease on tensioner replacement.
