High Precision 64 Pitch Spur for Racing Drivetrains

The 3Racing 64 Pitch Spur Gear 91T Ver.2, model number 3RAC-SG6491/V2, is manufactured to tight tolerances to improve gear engagement and reduce vibration. Its 64 pitch, 91 tooth layout helps maintain stable mesh and smoother acceleration in race conditions.

Engineered for Smooth Power Transfer

Built for hobbyists who tune their drive trains, this spur gear reduces backlash and supports consistent torque delivery. The construction focuses on long service life and lower wear under high load running.

Fits Multiple Chassis and Race Setups

Compatible with a range of 1/10 scale chassis that accept 64 pitch gearing, this spur is a practical upgrade for track and club racers. Use it when refining gear ratios or replacing worn factory parts to preserve performance.

Will this 91T spur work with my 1/10 touring car?

Check your chassis specification for 64 pitch compatibility and the available pinion spacing. When your chassis lists 64 pitch gearing, the 3RAC-SG6491/V2 will normally fit directly.

How should I set gear mesh with this spur?

Set a small, even clearance between pinion and spur teeth using a shim or paper method, then secure mounts. Proper mesh prevents premature wear and noisy operation.

Is this gear suitable for high torque brushless setups?

Yes, the 64 pitch 91T profile handles higher torque when installed correctly, but ensure your pinion choice and motor cooling match the increased load to avoid overheating or excess wear.
