Reliable gearing from 3RACING 3RAC-SG64121

The 3RACING 3RAC-SG64121 64 Pitch 121T spur gear is aimed at modellers seeking consistent gear ratios and clean torque transfer. It helps reduce drivetrain lash and keeps vehicle response steady.

Suitable applications

This 64 pitch spur is compatible with a range of vehicles built around the 64 pitch standard and works particularly well in 1/10 scale on-road cars where precise ratio control matters.

Installation and care

Match the spur with a 64 pitch pinion and set mesh carefully using a paint or marker to check contact pattern. Inspect the gear after heavy use and replace if tooth damage appears to avoid stressing the motor.

Yes, provided your car uses a 64 pitch gear train. Check your pinion is 64 pitch and that the gear housing can accept a 121T spur.
Incorrect mesh, debris ingress, and heavy gear lash are common causes. Regular inspection and correct alignment reduce wear significantly.
Use a marker to transfer the contact patch, then adjust pinion position until marks show even contact across tooth faces. Listen for smooth engagement at low throttle.
