Spinning your alternator passed the factory limit often leads to failure. Extend your alternator’s life by reducing its maximum RPM while maintaining sufficient charge at idle.


Our underdrive alternator pulley will help keep the rpms within a more reasonable range when spinning past the factory limiter.  Our pulleys are CNC machined from billet 6061 aluminum and are hard black anodized for a durable finish.
