Performance Pinion: 3RACING 3RAC-PG6426 64 Pitch 26T

For competitive tuners, the 3RACING 3RAC-PG6426 64 pitch 26T pinion combines a 7075 aluminium core with a hard coat surface to deliver repeatable engagement and reduced wear under race conditions. It is intended for precise mesh setups in 1/10 scale race cars.

Material Selection and Surface Hardening

7075 aluminium provides high tensile strength while keeping mass low for responsive drivetrain behavior. The hard coat increases surface hardness on the tooth flanks, helping preserve profile integrity across multiple events.

Compatibility, Ratios and Setup Notes

Use this 26T pinion to refine final drive for higher track speed or to fine tune lap-to-lap performance. Confirm shaft diameter, key alignment and set screw torque; small mesh adjustments yield measurable differences in noise, temperature and efficiency.

Technical FAQ

What is the recommended mesh tolerance for a 64 pitch pinion?

Aim for a very light, even backlash that allows smooth rotation without visible gaps or tight spots. Use feeler gauges or a thin shim method and recheck after a short run.

How does hard coating affect heat and wear during long runs?

The hard coat reduces surface abrasion, which can lower progressive wear; however, monitor motor and gear temperatures as higher loads still increase thermal stress.

Which spur combinations pair well with a 26T 64 pitch pinion?

Pair with a compatible 64 pitch spur of appropriate tooth count to achieve your target ratio. For racing, choose a spur that keeps motor current in a safe window while providing the desired lap times.
