American Racing Solutions provides the last racing belt tensioner you will every buy.

Anyone that is racing a supercharged muscle car knows that the stock belt tensioner was not designed to stand up the stress and the strain of racing with increased HP and torque. We are proud of our line of Racing Belt Tensioners, which are designed and fabricated from 6061-T6 Billet Aluminum (not cast) and they are all direct bolt on replacements for your stock tensioner (no adaptor plates or accessories needed).

Our Tensioners have been proven on the DYNO and the Race Track and will increase boost and HP by reducing or completely eliminating belt slip. As a result of our engineering and the use of custom fabricated springs, hardened steel shafts, needle bearings and bushings our Tensioners will outperform anything on the market. No more broken, shredded or melted belts. We are so confident that our tensioners will not break or bend, that we guarantee them for the life of your car.

Whether you are running a GT, GT500 or a Coyote engine, we have a tensioner that will fit your needs.Learn More
