Race-Grade Pulley for Yokomo Chassis

The Yokomo MS-503GP 38T pulley is a precision-machined aluminium component made for BD11, BD12 and MS1.0 gear differentials. Its construction focuses on repeatable gear engagement and resistance to track wear.

Precision Machining Benefits

Tightly machined teeth reduce play and help transmit torque more evenly across the gear train, contributing to consistent handling lap after lap.

Optimised Rotational Mass for Acceleration

By using a light but strong alloy design, the MS-503GP trims rotating mass so the drivetrain responds faster while remaining durable for regular use.

Specifications

  • Material: Aluminum
  • Teeth: 38T
  • Compatibility: BD11, BD12, MS1.0
Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Will this pulley change my handling?

Handling changes come from reduced drivetrain flex and smoother engagement rather than a change in ratio; drivers often notice crisper throttle feel.

Are there any break in procedures?

A short run-in at moderate speeds to settle parts and confirm mesh is recommended before pushing the car hard on track.

Can I use this with my existing diff bearings?

Yes, it is compatible with standard BD11/BD12/MS1.0 bearing setups, but ensure bearings are in good condition to avoid premature wear.
