Alternator Pulley - 7-Groove

The Alternator Pulley - 7-Groove by PROFORM is a precision-engineered serpentine pulley designed for high-performance engine builds and street applications where reliable accessory drive operation is critical. This component is essential for managing belt tension and rotational speed for your alternator, ensuring consistent power output across the entire RPM range.

Engineered with durability and precision fitment as primary objectives, this pulley delivers consistent belt contact geometry and minimizes slip, which is vital for charging system efficiency. The seven-groove design distributes load evenly across the belt, reducing wear on both the pulley and serpentine belt while maintaining the proper alternator speed ratio.

This pulley is ideal for builders installing upgraded alternators or restoring charging reliability after engine rebuilds. Its lightweight construction makes installation straightforward without requiring frame modifications or custom bracketry on most platforms, making it a great choice for mechanics and enthusiasts alike.
