SPE Adjustable Auxiliary Idler: Max Supercharger Belt Wrap, Min Belt Slip

This is the kind of part that doesn’t make noise, doesn’t add lights, and doesn’t impress your neighbors—yet it can absolutely save a Raptor R setup. The SPE adjustable aux idler is designed to put the idler right where it needs to be for belt control, maximizing wrap and reducing slip—especially when you’re running smaller blower pulleys. It’s billet, uses dual high-speed bearings, mounts to existing snout bosses, and requires no modifications. Fully assembled, hardware included, instructions included.
