Precision 48P Spur for Consistent Torque

The 3Racing 48P Spur Gear 72T Ver.2 is machined to a profile that promotes smooth engagement and steady torque flow under load. Its tooth geometry suits fine-tuned gear ratios where predictable acceleration and low backlash are priorities. This spur is a practical upgrade for anyone refining pinion choices and final drive ratios.

Is the 48 pitch size suitable for drift and touring setups?

Yes, 48 pitch is commonly used in both drift and touring classes. Check your gearbox spec to ensure matching pinion pitch and adequate spacing.

What should I expect in terms of durability?

When correctly meshed and paired with a suitable pinion, this spur offers reliable life for club racing and spirited track sessions. Track conditions and driving style affect longevity.

Can I change pinion size without issues?

Yes, but confirm the motor pinion and spur mesh for each pinion change. Smaller pinions raise RPM but increase stress, so adjust gearing with motor and ESC limits in mind.

Do I need special grease or lubricant?

Light gear grease or a dry film lubricant helps reduce wear without attracting excessive dirt. Avoid heavy pastes that can trap grit in off-road conditions.
