Idler pulleys are standard for all superchargers. Spare idler pulleys are made from high-quality aluminum. Idler pulleys allow you to reconfigure the supercharger belt routing on custom applications. Each idler pulley includes:
Fully assembled idler pulley
Two high-speed bearings
Shaft and threaded fastener
* Except for the T-Maxx 2.5, all supercharger assemblies use an aluminum stand off.
