Durable Pinion for Everyday Off-Road Running

The Yokomo BM-4821A Hard Steel Pinion Gear DP48-21T is made to last through repeated sessions, offering consistent tooth engagement and longer service intervals. Enthusiasts will appreciate the hard steel resilience when running varied surfaces.

What 48 Pitch and 21 Teeth Deliver

A 48 pitch with 21 teeth gives a practical compromise between acceleration and top speed, making this pinion suitable across many standard RC platforms. It pairs well with common spurs used in 1/10 scale machines.

Why Hard Steel Is Chosen

Hard steel is selected for its resistance to wear and ability to survive sustained friction. That toughness reduces the chance of sudden gear failure and keeps drivetrain feel consistent lap after lap.
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 check gear compatibility before buying?

Match the 48 pitch standard and 21 tooth count to your spur, and confirm the pinion bore and motor shaft size match to avoid fit issues.

Should I lube a hard steel pinion?

A light lubricant on the mesh can reduce wear and noise; avoid heavy greases that attract dirt, especially for off-road running.

Can I file or modify the teeth for better mesh?

Minor hand finishing can help settle mesh, but take care with hard steel and aim for smooth contact patterns rather than aggressive reshaping.
