Lethal Performance now offers a high quality 2.60" supercharger and auxiliary idler upgrade for the 07-2012 Shelby GT500's. The kit includes the Metco Motorsports  2.60" Supercharger Pulley and DivisionX 90mm Auxiliary Idler Pulley. Details about the combo can be found below...


Our supercharger pulley kit includes a 2.60" pulley ring which is anodized for a long lasting protective finish. We also include a mounting hub made from high grade steel and zinc plated for extra protection. Lastly we include the necessary bolts and washers to properly install the ring to the hub.

Our 2.60" pulley will add 4-5lbs of boost to your GT500 and when accompanied with an intake and tune you can expect gains of up to 145rwhp.

When installing a smaller supercharger pulley on your GT500, it not only creates slack in the stock belt but decreases the amount of belt to pulley surface area. To help prevent belt slip and allow you to use the stock belt, you'll want to install one of the DivisionX auxiliary idler brackets.
