Update Your Drivetrain with 3RACING 3RAC-SG4877

The 3RACING 3RAC-SG4877 is a 77T spur gear in 48 pitch format, aimed at improving meshing consistency in 1/10 on-road setups. It is a straightforward choice for racers and weekend drivers alike.

Where It Works Best

Designed for 1/10 scale on-road cars that specify 48 pitch parts, this spur meshes best with matching pinions to keep drivetrain losses and noise to a minimum.

Practical Fitment Tips

Ensure correct mesh by adjusting the motor mount until the pinion and spur meet smoothly. Secure setscrews and check for any lateral movement after a few runs.

Changing spur tooth count alters overall gear ratio and can change acceleration and top speed; plan pinion choice accordingly to achieve the result you want.
Use properly matched 48 pitch pinions, set a precise mesh, and keep bearings well maintained to reduce vibration and noise from the drivetrain.
Yes, with the right tools removing the motor or loosening the mount to swap spur gears is a common trackside task, but always recheck mesh after replacement.
