- Designed & engineered by the Original Equipment supplier of accessory drive tensioners and pulleys for this application
- Internal "round spring" technology to provide constant belt tension and alignment throughout its service life. The internal damping design provides quiet, smooth, system performance.
- A plastic pulley specifically molded with tight radial run out for reduced noise and longer life
- Due to the fact that belts and tensioners have similar Original Equipment "design life targets", it is often a best practice to replace the belt tensioner when replacing a worn or broken belt. Belt removal is required to change the tensioner. Therefore doing both together will extend accessory drive life and lower overall labor versus performing these services separately.
- Installation instructions included
