Arrowmax AM-MRX5-H0251B 20T Alloy Pulley for Mugen MRX5  [AM-MRX5-H0251B]

Rugged 20T Alloy Pulley for Mugen MRX5

Improve your Mugen MRX5 with the Arrowmax AM-MRX5-H0251B 20T pulley, CNC machined from 7075 T6 aluminum for a balance of strength and low weight. The precision finish is hard-coated to resist wear, and the drilled holes help shed debris so the pulley keeps turning cleanly under race conditions.

Engineered Precision for Belt Drive Efficiency

This Arrowmax pulley is tailored to the Mugen MRX5 chassis for a consistent fit and reliable operation. Using 7075 T6 alloy cuts mass while retaining stiffness, and the ported design reduces dirt buildup that can slow the belt system.

Race-Day Upgrade for Consistent Performance

The 20T pulley is a practical upgrade for racers refining acceleration and throttle response. Its lightweight construction lowers rotating inertia for crisper launches and smoother handling across variable track laps.
