BPS 10-Rib 76mm Smooth Idler Pulley (2007-2014 GT500)

This idler is a stock size replacement for Ford Part # 7R3Z8678A. Our pulleys are hard black anodized to ensure a durable and long lasting finish. They also come preinstalled with premium bearings. As much as this pulley can benefit the hardcore racer, this pulley is top quality and would make an excellent add-on to any show car. This pulley is also a direct replacement for the drive belt tensioner.

Weight comparisons:

Ford: 442g (0.97 lb)

Billet Pro Shop: 178g (0.39 lb)

To be installed with snap ring facing front of vehicle.

This is the stock 76mm size. Our 90mm version is larger but still lighter than factory, and the extra diameter buys more belt wrap on the supercharger pulley. Hide the bearing face and snap ring with a bearing finishing cap (P000). Doing the whole drive at once is the lightweight pulley package, and the rest are in BPS engine pulleys.
