Mercedes-Benz S550e Belts and Hoses

This Heavy duty belt tensioner is manufactured by one of the largest original equipment tensioner suppliers to ensure 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. This part corresponds to the 2012-2015 Mercedes-Benz C350,E350,CL400,E400,GLK350,SLK350 with 3.5L. 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.
