Stop your OEM belt tensioner bracket from bending with Steeda's new Tensioner kit! A major problem with Supercharged applications as the increased belt length and tension puts unwanted stress on the factory tensioner. A real problem is when you kick the clutch and pull the next gear the RPMS suddenly drop.

With the extra rotating mass of the supercharger and weight of all the accessories it will jerk the belt and sometimes hurt your OEM tensioner. It causes it to flex and in the end you usually end up with broken belts that are hard to find and expensive. A great fix for all blown Roush, Saleen and other bolt on supercharger applications. Kit is available with a factory pulley or an optional billet one.

Note: 555-3358 is designed for use with Whipple supercharger kits with a 3.625" - 3.25 blower pulley. These kits require a 90mm idler.

Product Reviews

Steeda makes quality Mustang mods, this belt tensioner ensures vehicle safety for boost applications.

I added this to my 2006 Saleen superchared GT and have not had any problems what so ever. Fit, finish and cost all were very good!
