Supercharged applications have an increased mass and accessory weight which can cause belts to wear out faster and eventually slip, resulting in expensive fixes. Roush’s tensioner adds longevity and durability to your belts preserving your S197 for years to come. This tensioner is a perfect replacement for blown Roush and Saleen bolt-on supercharger applications.
