Accurate spur gear for tuned drivetrain setups

The Yokomo ZM-S84 84 Tooth, 41 Pitch Spur Gear provides a stable gear interface for RC models that need consistent power transfer. Its exact tooth spacing helps reduce shock loading and offers predictable behaviour during acceleration and corner exits.

Improve drivetrain smoothness

Precision manufacturing keeps tooth profiles aligned for lower friction and quieter running. This makes it a practical upgrade when replacing worn gears or when refining drivetrain response for competitive driving.

Simple fitment across many models

The gear is engineered for compatibility with common spur-pinion arrangements. Check that your pinion and gearbox accept 41 pitch components and that the 84-tooth count matches your gearing targets.
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.

How do I match this gear to my pinion?

Confirm both parts are 41 pitch and count the teeth on your pinion. Use the recommended centre distance for 41 pitch to set correct mesh.

Is the Yokomo ZM-S84 suitable for off-road use?

Yes, it works for off-road vehicles as long as the chassis supports 41 pitch gearing. Regular cleaning helps prevent grit from accelerating wear.

Will this change my gear ratio significantly?

The tooth count sets the ratio. Swapping to an 84-tooth spur will alter overall gearing relative to your current spur, so recalc ratios if necessary.

Any tips for running-in the new spur?

Set a correct mesh, run the car gently at low speeds for a few packs, and then recheck mesh before pushing harder to ensure even wear.
