Replace the original 2.7" supercharger pulley on your 2013 or newer GT500 and gain 2-3 lbs of additional boost. Metco's one-piece pulley is precision-machined from high-grade steel and then coated with a durable Epoxy E-Coat for a stealthy appearance. The pulley bore is machined to exact specifications for a proper press-fit installation. K If this pulley is paired with Metco's MSI-90 Auxiliary Idler kit (listed in this section), the original supercharger belt can be retained and there will be no belt slip.
