Fixed Auxiliary Idler with Double Ball Bearing Pulley

The Snyder Performance Engineering SPE-P100120 Fixed Aux Idler is engineered to enhance the performance of your 2020-2022 Ford Mustang GT500's supercharger system. This unit consists of a precision CNC-machined billet aluminum bracket paired with an extreme-duty, double ball bearing, black anodized idler pulley. Its strategic placement, just to the left of the supercharger pulley, significantly maximizes belt wrap, achieving up to 270 degrees. This increased wrap is crucial for eliminating slippage, particularly when running smaller blower pulleys (2.6" and smaller are recommended). The idler assembly arrives fully assembled with stainless hardware and illustrated installation instructions. The unit requires no vehicle modifications for installation, offering a straightforward upgrade path for enthusiasts looking to optimize their supercharger's efficiency and reliability. It is designed to work in conjunction with the SPE GT500 blower pulley system.
