Description

The SPE Motorsport 2020-2022 GT500 Adjustable Auxiliary Idler is a performance upgrade designed to maximize belt wrap and eliminate slippage. It features a CNC-machined billet aluminum bracket and an anodized black idler pulley with Nachi dual high-speed bearings. The adjuster components and hardware are constructed from billet 304 stainless steel. This idler bolts directly to existing supercharger snout bosses, requiring no modifications to the vehicle.
