        This tensioner was a lot better than any of the after market versions supplied by local part stores (autozone, o'reilly). Thanks again AM for keeping my stang on the road with the best OPR parts on the market.

        Direct fit for OEM replacement (4v)

        This belt tensioner is a direct fit on my 99 Cobra 4v, although it also fits 2v models. Does what you would expect it to and is made from quality materials.

        5 1999 Cobra - Wes

        Great Tension

        I have a 1999 SVT Cobra and my old tensioner for some reason did not have a place to put in a socket to release the tension on the belt. I bought this one to replace the old one and release tension to replace the belt. It has a good fit and solved the problem completely. Definately a good product if your tensioner is not working very well
