Auxiliary Idler Kit, 90mm
2003-2004 Mustang Cobra
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 90mm idler pulley, which is the smaller 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 1: This kit is available with a larger 100mm idler pulley for applications using an overdrive (smaller) supercharger pulley under Metco Motorsports PN MCI-100, also listed in this section. Both 90mm and 100mm kits are available with a double-bearing idler pulley upgrade for severe duty applications.
Note 2: The third image shown of the idler kit installed shows an older design pulley without the bearing cover. All kits shipped now include the revised pulley design with the bearing cover. |
