      Eliminate Belt Slippage. Is belt slippage robbing your Supercharged SVT Cobra of power? Then reclaim it with a Metco Motorsports 90mm Double-Bearing Auxiliary Idler Pulley Kit from AmericanMuscle. The Metco idler pulley bolts up just to the right of the supercharger pulley allowing for maximizing belt wrap and to eliminate slippage.

      Superior Materials. The 90mm double bearing idler pulley and mounting bracket included in this kit are CNC-machined from billet aluminum for superior strength and bolt directly to existing bolt bosses with no modifications required for installation.

      Application. This Metco Supercharger Double-Bearing Idler Pulley Kit is specifically designed for use on the 2003 to 2004 SVT Cobra Mustangs equipped with the Supercharged DOHC 4.6L V8 engine, that have upgrade to a 2.7", 2.8", 2.9" or 3.0" Metco Motorsports Supercharger pulley.

        Idler Pulley

        It was the right idler pulley but wrong color. I ordered the polished finish and got a black and polished pulley. Went ahead and installed it anyway. Looks good with my black JLT cai.
