Replace the original 2.7" supercharger pulley on your 2013 or newer GT500 and gain 2-3 lbs of additional boost.

Our one-piece pulley is precision-machined from high-grade steel and then black-powdercoated for a stealthy appearance.  The pulley bore is machined to exact specifications for a proper press-fit installation.

If this pulley is paired with our MSI-90 auxiliary idler kit the original supercharger belt can be retained and there will be no belt slip.
