    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.

            Roush tensioner

            The Roush tensioner is a great upgrade to the factory tensioner. The Roush unit has a thicker arm and won't flex like the factory tensioner does when running higher boost levels. The Roush unit also has a stiffer spring, which helps eliminate belt slip.

            heavy duty app.

            I had just put a new S.C. belt on and it added a lot. So I still was not getting enough boost till, I put the heavy duty belt tensioner on and now its running great with no slip.

            Just recieved it.

            Just received the tensioner today and didn't install yet. It's beefier than the stock tensioner but I did notice it has a bearing made in China on the pulley? Thought Roush was all American? The reason I went with Roush was to get away from the stock tensioner with bad bearings. I'am going to install anyway. Hope it holds up to my Kenne Bell supercharger. What is Warranty on this tensioner. Sorry to be negative. Expected more for the money and name. Will do another review after the install.

            Tight

            I was using a Dayco tensioner that could not stand up in a supercharged application. This part looks well built and is doing what it's supposed to do. Keeping my belt tight.

            Best upgrade for your supercharged stang!

            Right off the bat you can see the difference once you have them both side by side. The Roush tensioner is much bigger and beefier than stock. Installing was a breeze, I’d recommend moving the coolant tank over just for extra elbow room. It’s a simple and inexpensive upgrade you can do to maintain the boost!

            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.
