Upgrade & Restore Your Wheel Balancer's Performance

The "A" Pulley is a professional-grade mechanical component designed specifically for wheel balancers. Engineered to exact factory tolerances, it replaces original equipment part number 8110915 to maintain balanced, concentric rotation and precise wheel balancing calibration.

Timely replacement of worn components and hardwares is critical to preventing high-speed vibrations, protecting sensitive piezoelectric sensors, and reducing expensive garage downtime.
