Setup focused 64 pitch spur for tuned performance

The 3Racing 64 Pitch Spur Gear 91T is built to support precise adjustments when you are trimming gearing for track conditions. Its tooth profile favours steady engagement, helping reduce chatter during high rpm runs.

Good match for varied on-road setups

With 91 teeth and a 64 pitch profile, this spur suits a wide selection of 1/10 scale on-road kits and aftermarket pinions. It makes swapping ratios straightforward when testing different performance targets.

Reliable for regular track use

Constructed to endure repeated practice and club racing, the 3Racing spur gear provides consistent operation over time. It stands up to frequent fitting and inspection cycles common in race prep routines.

If your pinions are 64 pitch and your chassis supports 91T spurs, it will fit; compare tooth count and centre distance to confirm correct mesh.
A 64 pitch gives finer tooth engagement for smoother operation, which helps tuning precision and reduces vibration in many on-road gear trains.
Check for wear or broken teeth during regular maintenance intervals, particularly after heavy runs or if you notice unusual noise from the gearbox.
