Racing Grade 26T Pinion for Tuned Drivetrains

The 3Racing 48 Pitch Pinion Gear 26T is produced from 7075 aluminum and receives a hard coating to enhance tooth surface durability. It is specified for users who need predictable gear behaviour and minimal rotational mass in tuned vehicles.

Engineering Notes on Material and Finish

7075 aluminum delivers high tensile strength while keeping weight low; the hard coat improves abrasion resistance under repeated engagement cycles. This helps maintain gear geometry for consistent performance during setup changes.

Compatibility and Tuning Considerations

Suitable for standard 48 pitch spurs on 1/10 scale platforms, this 26T pinion is ideal when experimenting with gear ratios to refine acceleration, top speed, or motor load characteristics.

What is the best way to verify pinion balance before high RPM testing?

Spin the pinion on a low friction mandrel and observe for wobble. Any imbalance can cause vibration that accelerates wear on bearings and motor shafts.

How should I approach gear ratio changes with this pinion?

Adjust in single-tooth steps while logging lap times or acceleration; small changes reveal the effect on motor load and top speed without introducing drivetrain stress.

Any recommendations for preserving the hard coating during setup?

Avoid abrasive cleaners and excessive force on teeth during fitting. Use proper mesh setting and check tooth engagement under power to ensure the coating remains intact.
