The Yokomo B10-630OA aluminium outer drive pulley is crafted to improve belt life and drivetrain feel on BD10 cars. The 20-tooth layout spreads load across the belt while a hard surface coating reduces drag and wear.
Lightweight yet robust, this pulley suits several Yokomo chassis such as the MRTC-BD10FF, MSR-BDFWD and MSR-010 line. It is a practical upgrade for racers and weekend tuners wanting reliable performance gains.
