Enhance drivetrain smoothness with the 3Racing 48P 72T spur

The 48 pitch, 72-tooth spur gear from 3Racing offers consistent tooth engagement to help reduce drivetrain vibration and deliver steadier torque. It is a practical part for routine tuning and maintenance tasks.

Practical benefits of the 3Racing spur gear

Precision Engineering: Accurate 48 pitch machining ensures reliable mesh and helps minimise drivetrain noise under load.
Durable Material: Made to cope with regular running, keeping performance steady over time.
Compatibility: Suitable for models that require a 48 pitch spur, allowing simple upgrades or replacements.

How do I confirm the pitch is correct?

Check your current spur and pinion markings for 48P, or measure tooth spacing. Only match 48 pitch pinions with this spur gear for proper engagement.

Will changing to 72T affect gearing ratios much?

Increasing spur teeth changes the final drive ratio, generally giving stronger acceleration at the cost of a small reduction in top speed depending on pinion choice.

Any maintenance advice?

Keep the gear clean, check for chipped teeth after impacts, and verify fasteners are secure before each session.
