76mm or 87mm Grooved Six-Rib Idler Pulley
Select Modular Ford Applications, Including 2005-2010 Mustang
76mm or 87mm
Fits 2005-2010 3V Mustang, and Similar Modular Ford Applications
The 87mm version of this grooved idler pulley is the same pulley that is included in our MIP-2005 Idler Pulley Kit for the 3V Mustang application. The 76mm size is used in our MCI-AD kit for the Mustang Cobra accessory-drive. This pulley style (in both of these sizes) is used in many Ford applications, including earlier modular applications and the accessory drive in select factory-supercharged cars.
The 87mm version of this pulley measures about 3.4" from belt surface to belt surface (the pulley flanges not included in the measurement), and the 76mm version has an effective diameter of 3.0". These pulleys use the same certified 6061 aluminum, black anodizing, and high-speed, high-load bearings as our pulleys designed for use on the supercharger drive. Both pulley configurations ship with a billet bearing cover and stainless M8 socket-head fastener as shown, intended to install as a direct replacement for the original pulley in appropriate applications.
