Upgrade Your Yokomo Gear Differential

The MS-503GP 38T pulley from Yokomo is produced from hardened aluminum and precision machined for tight tolerances in BD11, BD12 and MS1.0 gear differentials. It is intended to add robust service life while keeping the drivetrain light.

How the MS-503GP Improves Drivability

The fine machining reduces gear lash and promotes smoother power delivery, which helps with consistent throttle response and corner exits under competitive conditions.

Built for Consistent Track Use

Its low rotating mass helps with quicker spool up and can make handling feel more responsive without compromising strength.

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.

Can I replace a plastic pulley with this metal one?

Yes, replacing a stock plastic pulley with the MS-503GP improves wear resistance, but check mesh and bearings for metal-on-metal contact precautions.

Does the pulley change gear ratios?

The tooth count stays at 38T, so gear ratio is unchanged; performance gains come from durability and reduced play.

Is extra balancing required?

The MS-503GP is made to tight tolerances and normally does not need additional balancing, but inspect for burrs before fitting.

What fasteners are recommended?

Use the correct sized retaining screw specified for the gear differential and apply proper threadlock where appropriate on metal threads.
