Track oriented 91T spur for consistent drive

The 3Racing 64 Pitch Spur Gear 91T is aimed at hobbyists who swap ratios frequently to find the best lap times. Its fine pitch assists in stable engagement, reducing lash during acceleration and braking transitions.

Works with common 1/10 on-road layouts

This spur gear's 91-tooth count and 64 pitch fit many standard on-road gearboxes, making it a practical choice for quick ratio testing and incremental tuning between sessions.

Made to last through practice sessions

Built to stand up to regular use, the 3Racing spur gear offers serviceable life across repeated runs. It supports an active tuning routine where parts are swapped and inspected often.

Can I use this spur for both speed and torque tuning?

Yes, changing to a 91T spur alters the final drive ratio and can be used to favour acceleration or top speed depending on your pinion choice.

What should I watch for when installing this gear?

Ensure correct centre distance and a small, even mesh pattern; inspect for smooth rotation before sealing the gearbox or tightening the motor mount fully.

Does this spur suit high rpm use?

The 64 pitch tooth form encourages stable contact at higher rpm, but always monitor for excessive noise or chipped teeth after intense runs.
