Race-Tuned 87T 64 Pitch Spur for Performance Setups

The 3Racing 64 Pitch Spur Gear 87T Ver.2 is designed for competitive tuning, providing consistent tooth contact to support predictable power delivery under hard driving. Its 87-tooth geometry allows fine adjustment of final drive ratio to suit motor rpm curves and circuit requirements. When used in a race setup, focus on precise mesh, secure mounting, and harmonising pinion selection to extract repeatable lap times.

What motor rpm range pairs well with an 87T spur?

Pair the 87T with a pinion that keeps the motor within its optimal rpm band on your chosen track. Use telemetry or rpm testing to avoid over-revving or lugging the motor during acceleration zones.

Any setup tips for minimising power loss?

Ensure concentric mounting, correct shim stack, and minimal slop in bearings. Use a high quality pinion and maintain lubricated but clean contact surfaces to reduce frictional losses.

How should I validate gearing on track?

Run controlled laps, monitor motor temperature and lap consistency, then iteratively adjust pinion size. Track data over multiple runs to confirm changes improve average lap time rather than a single fast lap.
