These pulley rings are designed for use with Metco Motorsports two-piece supercharger pulleys. If you already have a Metco supercharger pulley on your Lightning or Cobra, one of these rings is all that is needed to change the boost level on your vehicle. These pulley rings will bolt to your existing pulley hub using the same (4) fasteners, and no special tools are required for the change.
Our pulley rings are precision-machined from billet aluminum and then black anodized for long lasting surface protection. Listed below are approximate boost gains that can be expected when installing these pulleys on a Mustang Cobra:
2.70: +5-6 lbs 2.80: +4-5 lbs 2.90: +3-4 lbs 3.00: +2-3 lbs
We recommend the use of our Auxiliary Idler Kit with these overdrive supercharger pulleys to maximize belt wrap and to minimize belt slippage. These idler kits are available for the both the Cobra and the Lightning. Kit includes 1 pulley ring
