    Proper Belt Tension. Is your 2005-2010 Mustang GT’s OEM or replacement serpentine belt slipping out of place or squealing? You need a Heavy Duty Belt Tensioner from Roush Performance. This Tensioner is designed to provide a suitable belt tension and will make your ride noiseless and more comfortable on the road.

    Heavy Duty Construction. Installing a Roush Heavy Duty Belt Tensioner is a recommended upgrade, especially if you have recently installed a Roush supercharger on your GT. It has a heavy duty construction that enables it to handle extreme rotational forces from the supercharger, making it ideal for applications such as racing. There’s more; Roush Performance builds its tensioners from industrial grade cast aluminum spring case for ultimate strength and durability.

    Genuine Ford Part. The Roush Heavy Duty Belt Tensioner is crafted to match your GT’s factory specifications. Also, it is made from OEM-grade materials thus giving it the ability to withstand aggressive driving styles without cracking or underperforming. Its permanently sealed bearings, similarly, guarantee long-term and dependable maintenance-free operation.

    Direct Installation. Since Roush Heavy Duty Belt Tensioner fits your Mustang’s factory specifications, installing it is relatively easy. You do not need to undertake any modifications to your GT. Basic tools are required to complete installation, and the process lasts approximately one hour.

    Warranty. Roush Performance backs its belt tensioners with a unique Roush Limited Warranty that covers manufacturer’s defects unless stated otherwise.

    Application. Roush Heavy Duty Belt Tensioner is designed to fit all 2005 to 2010 Ford Mustang GT models.

      Stop the SLIP

      Do yourself a favor and buy this tensioner! I wasted my money on a more expensive thumper and this worked better.

      Much Better Tensioner than Stock

      I replaced my factory tensioner with the Roush HD tensioner. Much more force on the belt than the factory tensioner, had to use a breaker bar to flex the tensioner when installing the belt. I run a 2.4L Kenne Bell supercharger with a Gates HD belt and this tensioner keeps everything tight with zero slip.
