Race setup focus for 3RACING 3RAC-SG64112 64 pitch

The 3RACING 64 Pitch Spur Gear 112T is presented for competitive drivers seeking fine incremental gearing. Its 112 tooth profile provides predictable engagement and allows accurate ratio adjustments for tuning to specific track characteristics.

Performance tuning and ratio control

With a dense tooth count, the 112T spur produces smoother load distribution and reduced step change between ratios, aiding traction control and throttle precision. It is suitable for high rpm brushless applications when correctly matched to pinion and ESC settings.

Integration and setup best practice

Intended for standard 1/10 64 pitch gearboxes, the 3Racing spur installs with minimal modification. Confirm shaft spacing, set correct mesh using feeler gauges or shims, and verify no binding across a full rotation before finalising setup.

What pinion range pairs well with the 112T spur for sprint tracks?

Choose a pinion that achieves your target rpm window without overloading the motor; sprint circuits often use mid to small pinion sizes to balance acceleration and top speed.

Any mesh setup recommendations for race durability?

Set a consistent minimal clearance across the gear face, secure the pinion, and recheck after a few laps. Proper mesh reduces tooth fatigue and maintains efficiency.

How does tooth count influence thermal load on the drivetrain?

A larger tooth count can distribute torque over more contact area, which can lower localized heating if mesh and lubrication are correct; overall thermal behaviour still depends on motor and ESC tuning.
