    Eliminate Belt Slippage. Is belt slippage robbing your mighty Shelby GT500 of power? Then reclaim it with a C&L Performance 90mm Double-Bearing Auxiliary Idler Pulley Kit from AmericanMuscle. The C&L idler pulley bolts up just to the left of the supercharger pulley allowing for maximizing belt wrap and to eliminate belt slippage.

    Three Position Adjustable. C&L engineered their Dual Bearing Idler Bracket with three preset pulley positions to remove the desired amount of excess belt slack and to avoid the annoying problem of unwanted belt slippage that occurs over time on lesser "slotted" brackets.

    Superior Materials. CNC-machined in the USA from billet aluminum for superior strength, this C&L Performance 90mm double bearing idler pulley and mounting bracket are completed in a black anodized finish for impressive good looks and long lasting resistance to surface wear and corrosion.

    Application. This C&L Supercharger Double-Bearing Idler Pulley Kit is specifically designed for use on the 2007 to 2014 Shelby GT500 Mustangs equipped with the Supercharged V8 engine, that have upgrade to a smaller diameter supercharger pulley. Technical Note. Will

    not fit with Whipple 4.0L supercharger.

            Works great with supercharger pulley upgrade

            Easy to install. Move coolant hoses to make your life easier. Pulley is adjustable and eliminates belt slippage

            No more slipping..

            Adjusted the pulley all the way up. Installed it with the stock pulley on the super charger. May go smaller but it’s adjustable. More surface area for the belt I think helps. Haven’t seen any rubber on the charger snout. And it’s quiet.

            Easy install

            The idler was very easy to install. I especially like that it is black because it keeps the stock look.

            Awesome

            Not a bad install tensioner was a bit hard. Pulley looks great on the car and so far no more slippage!
