Race-Grade 21T Spur for Kyosho RRR Evo./SR

The Kyosho VZW231-21B second spur gear features 21 teeth and a 0.8 module pitch, produced in a hard material for improved resistance to wear. It provides steady power transfer and consistent tooth contact, making it a dependable replacement for track-focused vehicles.
Remark :
Due to limited stock availability, please notice that some Kyosho 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.

Does this change my gear ratio?

This is a 21T spur, so the tooth count determines ratio. Replacing like-for-like with another 21T keeps the same ratio; changing tooth count will alter final gearing.

Any installation advice for best mesh?

Set pinion mesh with a few test runs and fine adjustments, then secure the pinion and check for smooth rotation without binding to protect teeth and bearings.

When should I replace this spur?

Replace the spur if you spot chipped teeth, uneven wear patterns, or if mesh adjustments no longer restore quiet running, to avoid driveline issues during a race.
