This billet idler pulley is identical to the Metco Motorsports MIP-90 idler pulley except that is 10mm larger. The larger size is designed for use in auxiliary idler applications where a smaller than stock supercharger pulley is installed.
This pulley is CNC-machined from billet aluminum and black hard-coat anodized on the belt surface and back side for long-lasting surface protection. A heavy-duty bearing is precision-fit into the center section, and a snap-ring ensures everything stays in place.
The kit includes a billet bearing cover and a stainless steel socket head fastener to mount this idler pulley to the original or Metco Motorsports pulley mount. This pulley is designed for use with an 8-rib belt and is 1.5" wide at the belt surface.
Note: This pulley is also offered in a 1.0" width for use with a six-rib belt. The offset on the six-rib style is suitable for use on the accessory drives of most factory supercharged and non-supercharged applications.
