Billet Idler Pulley 76mm
6-Rib, 8-Rib or 10-Rib Drive
Priced Individually
Like all Metco Motorsports idler pulleys, these 3.0" smooth idler pulleys are precision-machined from a single piece of certified 6061-T6 billet and then hard-coat anodized on the belt surface and rear face. A billet bearing cover with a stainless-steel socket head fastener is included.
We offer our 76mm pulleys in three different configurations, for 6, 8 and 10-rib drive belts. The 6-rib (single-bearing) version of this pulley is 1.0" wide at the belt surface, with a pulley offset to match what is used on the accessory drive in the Modular Ford application. This version of this 76mm pulley can be used as a direct replacement for the smooth idler on the tensioner arm of many Modular applications using a 6-rib belt. The 8-rib version (also single-bearing) of this pulley is machined with the same offset as is used on the supercharger drives of the Mustang Cobra, the Lightning truck, and the GT500. This 8-rib pulley is 1.5" wide at the belt surface, similar to OEM supercharger idler pulleys.
The custom 10-rib double-bearing version of this pulley measures 1.75" across the belt surface, and like the 8-rib version it shares the offset of pulleys intended for use in the Modular Ford supercharger drive (Cobra, Lightning, etc). These pulleys are offered in this particular size and style to facilitate custom installations, and it is up to the installer to verify proper fitment prior to ordering.
Please choose the style of pulley you wish to purchase by selecting the appropriate option in the product listing above. Pulleys are priced individually.
