Upgrade your pulley to Ceramic Bearings! 


Serious racers are constantly pushing the envelope and everyone knows that shaving off .001’s of a second from their ET which translates into more win lights.

Ceramic hybrid bearings use ceramic balls and steel races. Ceramic balls weigh up to 40% less than steel balls, depending on size. This reduces centrifugal loading and skidding, so hybrid ceramic bearings can operate up to 50% faster than conventional bearings. This means that the outer race groove exerts less force inward against the ball as the bearing spins. This reduction in force reduces the friction and rolling resistance. The lighter ball allows the bearing to spin faster, and uses less energy to maintain its speed.

Ceramic silicon nitride balls exhibit much greater hardness than steel balls resulting in at least 10 times greater ball life due to the ability to hold the surface finish longer. The ball has dramatically smoother surface properties than the best steel ball resulting in less friction between the balls and bearing race surfaces. Thermal properties are also dramatically improved over steel balls resulting in less heat buildup at high speeds. Ceramic has 35 percent less thermal expansion, 50 percent less thermal conductivity, are lighter weight and are non-corrosive.

We are so confident that our Street Performance Belt Tensioners are the strongest and most reliable on the market that we guarantee our product for life against bending or breaking under normal use.


American Racing Solutions

American Racing Solutions believes in the age old adage that “necessity is the mother of all invention.”  Anyone that is racing a supercharged muscle car knows that the stock belt tensioner on their car 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 and Pulleys, which are designed and fabricated from 6061-T6 Billet Aluminum (not cast).  Every item in the line has been designed to be a direct bolt on replacements for the original/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.  Every tensioner that we sell is guaranteed that it will not break or bend.  Yeah, they’re that good.

In addition, we pride ourselves on our partnership with our customers and our racing partners.
