The SPE 2023+ Raptor R Adjustable Auxiliary Idler consists of a precision CNC-machined billet aluminum bracket and extreme-duty double ball bearing idler pulley, anodized black. Adjuster components and hardware are made of billet 304 stainless steel.
The adjustable auxiliary idler bolts to existing bolt bosses on the vehicle's supercharger snout and locates the pulley just to the left of the supercharger pulley, maximizing belt wrap and eliminating slippage. It's designed to work in conjunction with the SPE 2023+ Raptor R Blower Pulley System and pairs best with a 2.6" or smaller blower pulley. No modifications to the vehicle are necessary.
The Adjustable Aux Idler allows you to dial in the perfect amount of wrap with varying belt lengths and/or pulley sizes. Ships fully assembled with the required fasteners and illustrated installation instructions.
