Durable 72T Spur Gear for Versatile Setups

The 3Racing 48P Spur Gear 72T Ver.2 combines a robust tooth profile with stable engagement to handle spirited driving and repeated sessions. Its 72 teeth give a balanced final ratio option for off-road and on-road rigs where durability and consistent feel matter. Proper mesh and alignment will maximise service life.

Will this spur survive heavy off-road use?

With correct mesh and routine inspection, the 48 pitch 72T spur performs well in off-road use. Avoid excessive side loads and keep the drivetrain clean to extend life.

What motor and pinion pairings work best?

Pair the spur with pinions matched to your motor RPM and torque. Lower tooth pinions raise acceleration; higher tooth pinions give more top speed but place more stress on the gear teeth.

How often should I check the spur for wear?

Inspect the spur after every few sessions or after any impact. Look for tooth deformation, gouging or uneven wear and replace when performance drops.
