This supercharger pulley ring kit is based on our MSP pulley kits, but this kit includes only the aluminum 3.00" pulley ring.

If the vehicle is already equipped with a Metco Motorsports two-piece supercharger pulley, this ring can be installed in place of the existing pulley. THIS IS TO GO BACK TO STOCK BOOST. 3.0 IS THE STOCK SIZE. This pulley ring is CNC-machined for precision fit and hard-coat anodized to resist wear and surface corrosion. The ring bolts directly to the steel hub, and if replacing an existing overdrive pulley ring, the boost level will be returned to the stock level.
