Track-Ready 3Racing 64 Pitch Spur Gear 78T

If you want tighter control and cleaner power delivery, the 3Racing 64 Pitch Spur Gear 78T is a straightforward upgrade. The finer 64 pitch tooth form and 78 teeth provide a good compromise between torque and top speed, helping your car feel more predictable on technical layouts.

Benefits for racers

Made from durable materials to resist wear, this spur gear reduces friction and keeps gear mesh consistent under load. It mates with standard 64 pitch pinions and suits many 1/10 scale touring and off-road kits, offering a reliable way to improve drivetrain efficiency.

Which cars typically use this 64 pitch 78T spur gear?

Most 1/10 scale RC cars that specify 64 pitch gearing will accept this 78T spur as long as the chassis allows the larger diameter. Check your manual for clearance.

Will this gear change gearing ratio dramatically?

Moving to a 78-tooth spur raises torque at the wheel compared with smaller tooth counts, improving acceleration at the cost of some top speed.

Any maintenance tips to extend gear life?

Keep the mesh set correctly, avoid metal-on-metal contact with misaligned pinions, and inspect for wear after heavy runs to get the best life from the spur.
