If you want to increase boost, horsepower and top end with your 5.0 GT motor and Edelbrock
2650 Supercharger, this will help. Our tensioner is fabricated from 6061-T6 Billet Aluminum,
not cast. Internal components include a TGP shaft, hardened bushings, proprietary spring and
thrust bearings make this the strongest and smoothest belt tensioner on the market. It has been
tested and proven on the DYNO and the Track and will reduce if not completely eliminate belt
slip. Best of all it is a direct bolt on replacement for the stock unit, no brackets, fittings our
adapters are needed. We are so confident that our tensioner will not bend or break that we will
guarantee it for the life.

a 10 rib pulley can be ordered on a custom basis.
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 nitrite 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.
