Lethal Performance is proud to offer our own supercharger pulley for the 2007-2010 GT500. 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 running our 2.60" upper pulley with the stock belt you'll also need to run a Metco MSI-90 or MSI-90D in order to take up the slack in the belt from the smaller diameter pulley.
NOTE: Running this pulley will require custom tuning.
