The Thump RRR Racing tensioners were built with 2 things in mind. Prevent Belt Slip and Tensioner Failure. It's a pretty good bet that if you run your car hard a broken tensioner or belt slip is something you''ll most likely encounter if you haven't already. That's why Thump RRR Racing designed a piece which is 50% thicker than the stock and comes with a lifetime warranty.
The Thump RRR Racing Tensioners are available many 99-10' mustangs and can be found on our website by following the links below.
