Competition focused 3Racing 3RAC-SG6476 spur gear

The 3Racing 64 Pitch Spur Gear 76T is intended for racers who require repeatable engagement and stable drivetrain response. It works well when integrated into a tuned gearbox where precise backlash and gear alignment are prioritised.

Tuning friendly tooth form

The 64 pitch profile provides finer contact patches, enabling closer gear setup tolerances. That allows experienced tuners to dial mesh and backlash to match motor characteristics and track conditions without sacrificing tooth life.

Value racing upgrade

As a direct replacement spur, this 76T option offers consistent geometry that supports predictable lap to lap behaviour. It is well suited for drivers who focus on setup stability and straightforward upgrade paths rather than experimental materials.

What backlash should I target for a tuned setup?

Aim for minimal, consistent backlash that prevents binding at high RPMs. Fine pitch gears like this typically run tighter than coarse pitch; measure under load and adjust incrementally.

How does gear choice affect thermal load?

Tighter mesh and smoother engagement reduce micro-slippage and heat generation. Maintain clean lubrication and monitor motor temps after any gearing change to confirm acceptable thermal behaviour.

Is this gear compatible with racing pinions?

Yes, provided the pinion is the same 64 pitch. Using quality, dimensionally accurate pinions ensures consistent contact patterns and prolongs gear life in race use.
