This popular kit is designed to bolt on with no modifications and virtually eliminate belt slippage at the supercharger pulley. The included aluminum mounting bracket is precision-machined and mounts to existing bolt locations, and the unique design provides unmatched durability and strength.
This kit includes a black hardcoat-anodized 100mm idler pulley, which is the larger size that serves to maximize belt wrap in applications using stock size supercharger pulleys.
The kit includes a billet bearing cover for the pulley, and illustrated installation instructions are provided. This product is an original Metco Motorsports design that has been copied a number of times, but none of the copies match the quality and precision fit of the original.
Note : This kit is available with a smaller 90mm idler pulley for applications using a larger supercharger pulley under Metco Motorsports PN MCI-90, also listed in this section. Both 90mm and 100mm kits are available with a double-bearing idler pulley upgrade for severe duty applications.
