Engineered Spur Gear for Consistent Drive

The Arrowmax AM-664074 Super Differential Gear is machined to a 64P standard with 74 teeth to provide reliable engagement and smooth torque transfer across hobby RC drivetrains. Its profile helps reduce irregular loading on adjacent components.

Suitable for Tuning and Replacement

This 64P 74T spur fits a variety of chassis that call for 64P gearing, making it a practical choice when replacing worn parts or adjusting final drive ratios for track or club use.

Practical Installation and Care

When fitting the Arrowmax AM-664074, set an appropriate backlash and check alignment to limit wear. Remove grit after off-road running and inspect teeth periodically to maintain peak performance.

How do I confirm the spur will fit my chassis?

Measure your current spur tooth count and the centre distance to the pinion. If your setup uses 64P standard parts and the distance matches, this 74T spur should fit as a direct replacement.

Can this handle higher torque motors?

The gear is designed with accurate tooth geometry to withstand normal hobby loads. For very high torque applications, check your whole drivetrain and monitor for accelerated wear.

What signs indicate the gear is worn?

Watch for increased backlash, chipped or rounded teeth, and unusual noise under load. Any of these signs mean it is time to replace the spur to protect other parts.
