COPO

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.

This tensioner was born from pure necessity.  For those racing the factory supercharged COPO there was one chronic problem.  The tensioner provided (designed for commercial truck engines) could not handle the power of this racing package.  After constantly breaking tensioner arms and mounts one race team turned to us to design a better/more durable tensioner.  For almost 2 years, this was one of the best kept secrets at the track.  In 2016, competitive advantage had given way to friendship and comradere and the word quickly spread making this one of our best-selling models.  While this is a direct bolt on replacement for the COPO using the 2.9L Whipple Supercharger kit, it can be used in other applications.  With the addition of a 1-1/4” spacer we recently fitted this tensioner to a 2015 Silverado with a 6.2L engine featuring the 2.9L Whipple.
