Dial in drive with the 3RACING 48 Pitch Spur Gear 89T

The 3RACING 48 Pitch Spur Gear 89T is built to help hobbyists optimise drivetrain behaviour without overcomplicating the setup. It delivers consistent meshing for predictable shifts between speed and acceleration.

Suitability and fit

This 89T spur gear fits many common 1/10 scale platforms and works well for both track-focused cars and everyday club rigs. Use it to move your gearing toward higher top speed or to regain torque for tighter tracks.

Common uses

Track tuning: Adjust final drive for better lap times on sealed surfaces.
Street and park running: Improve smoothness and gear engagement for casual use.
Light off-road: Trade a bit of top speed for stronger low end when needed.

Will this spur gear fit belt or shaft drive gearboxes?

Check your gearbox spec and pinion clearance; the 48 pitch 89T is generally used with compatible 48 pitch pinions and common 1/10 gearboxes, but confirm tooth depth and mounting before fitting.

How does 48 pitch affect durability?

A 48 pitch gear offers a good balance of tooth strength and fine engagement compared to coarser pitches, making it suitable for a wide range of motors and power levels.

Any tips for installing the spur gear?

Ensure pinion alignment and backlash are set correctly, check for mesh noise at low throttle, and re-check after a short run as gears often bed in during initial use.
