Description
Better Performance. Whether you're running a smaller pulley on your blower for bigger boost or just looking for stronger performance from your Cobra, this belt tensioner kit is a great addition to your Mustang. It uses factory mounting points on your engine, adding another tensioner pulley that changes the angle of your supercharger belt and creates more wrap around your blower pulley. The result is more contact area between your supercharger belt and your pulley, meaning less belt slip.

Ideal for Big Boost. If you're running a smaller pulley to dial up higher boost on your Cobra, this belt tensioner kit is a must-have to make sure you're getting the most from your mods.

Premium Quality. This premium quality pulley is made from billet aluminum for durability and a great underhood look.

Complete Kit. This kit includes the 100mm (OEM) pulley, mounting bracket, and all necessary hardware for a hassle-free, straightforward installation.

Application. This belt tensioner kit is designed to fit 2003-2004 Mustang Cobras.

    Must Have

    This Idler Pulley is a must have if you are going with a 2.8" S/C pulley. Really works awesome and greatly reduces belt slippage. Install is a breeze. My only complaint would be that Steeda switched from black to chrome. A little frustrating when you're trying to keep everything under the hood looking uniform. For that I take one star away.

    Steeda Cobra Belt Tensioner

    I compared the design and quality of this tensioner to another brand. The Steeda only uses one bearing compared to the two bearings of the other brand. They are both the same bearing number 6203, which is a standard bearing industry wide. So I returned the Steeda in favor of the other brand. Both use CNC process on T6061 Aluminum.

    Decent, but bearing failed already.

    Good product over all, but the bearing failed pretty quick. Maybe it was just one of the bad apples, but since its been installed it has a squeal. Other than that, great product.

    Very easy bolt-on. Stops belt slip and loss of horse power. It looks awesome on the car.

    This product is a great fit.

    Fast and easy install , does give the belt much needed tension when changing the size of your supercharger pulley.

    The tensioner was easy to install, looks good and eliminated belt slip at the blower pulley.
