STM 10% Under-Driven Alternator Pulley with Raised Guides for Evo 4-9 4g63

The STM 10% Under-Driven Alternator Pulley with Raised Guides was originally designed to help stop the belt from jumping off at high RPM. With the amount of requests we’ve had for this product from the racing community, we are very pleased to announce the release! This new revision makes the pulley 10% under-driven and lighter than stock- lightening the load on your alternator. Fits all the Evolution IV-IX models and works with OEM and stock replacement belts.
