Fine gear control with 3RACING 3RAC-SG64121

The 3RACING 3RAC-SG64121 delivers consistent tooth engagement for hobbyists who want to refine gear ratios. It helps smooth power delivery and keeps drivetrain behaviour predictable during spirited runs.

Where this gear works best

This 64 pitch 121T spur is compatible with vehicles built around the 64 pitch standard, and it is particularly suited to 1/10 scale on-road machines. It lets you tweak ratio choices without compromising mesh quality.

Fitting advice

Always match the spur with a 64 pitch pinion to achieve correct mesh. After installation, run a mesh check at different throttle levels and inspect the gear after high-use sessions to extend service life.

Is the 3RAC-SG64121 suitable for brushless motors?

It works with setups that use 64 pitch gears irrespective of motor type, but ensure the motor mounting and pinion pitch match the spur to avoid fit issues.

What maintenance keeps it running smoothly?

Keep the gear clean from grit, check mesh alignment regularly, and inspect for chipped or worn teeth after heavy sessions to avoid drivetrain damage.

Can I use the gear for off-road cars?

While compatible with 64 pitch systems, this 121T spur is optimised for on-road scaling; off-road layouts may require different ratios or protection from debris.
