Performance Gear for Ultima

The Kyosho UB050-78 spur gear is crafted for lap-focused drivers. Featuring a 48-pitch, 78-tooth configuration, this gear is matched to the Ultima RB7.5 family and helps smooth out power transfer while sharpening throttle response. Accurate dimensions provide consistent engagement and predictable handling when dialing in your setup.

Accurate Mesh and Adjustment

Specifically intended for the Ultima RB7.5, the Kyosho UB050-78 delivers reliable tolerances and durable operation. Its 48-pitch specification works with standard 48-pitch pinions, allowing easy changes to gear ratios for different track surfaces or motor setups.

Made to Last Under Load

Produced from high-grade composite material, the spur gear stands up to repetitive stress and reduces wear on mating parts. The solid construction helps maintain consistent driveline feel through extended race days.
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.

Can I use this gear with non-Ultima chassis?

While the gear is designed for Ultima RB7.5, it may fit other cars that accept a 48-pitch spur and share similar mounting geometry. Verify shaft clearance and mesh before use.

What cleaning routine is recommended?

Remove dirt and grit after each outing, gently brush teeth, and inspect for wear. Light lubrication on bearings helps overall drivetrain health but avoid heavy greases on the gear teeth.

Does the material affect gear noise?

Composite construction can dampen noise compared to metal gears. Proper mesh and alignment are the main factors in reducing whine and chatter.

Is this the original equipment part?

This product matches the specification used on the Ultima RB7.5 series and is suitable as a replacement or spare for that model.
