Mustang GT Street Performance Belt Tensioner 2000-2004 (Tensioner Only - No Pulley)

If you are running a supercharged GT then you know that your factory belt tensioner was not designed to stand up to the stress and strain of the added HP and Torque, especially if you are racing.  Our Street Performance 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, which will increase boost and HP.  Best of all it is a direct bolt on replacement for the stock unit, no brackets, fittings our adapters are needed.  Recommended for cars making up to 700 HP.  We are so confident that our tensioner will not bend or break that we will guarantee it for the life.

Requires the use of a double bearing pulley

When ordering be sure to choose the right pulley for your application. 
We offer 70 or 76 MM double bearing pulley in either smooth or grooved.

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 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
