Precision Spur Upgrade from 3RACING

The 3RACING 48 Pitch Spur Gear 78T, model number 3RAC-SG4878, is a practical option for 1/10 on-road applications. It helps ensure smooth torque transfer and predictable drivetrain behaviour during track sessions.

Designed for 1/10 Touring and On-Road Cars

The 78-tooth configuration offers fine steps when changing overall gear ratio, making it useful for drivers trimming performance for different circuit layouts.

Durable Design for Regular Use

Built to resist wear under normal running conditions, the spur supports frequent track days while keeping gear mesh stable and predictable for longer service intervals.

Will the 78T work with brushed and brushless setups?

Yes, the spur suits both brushed and brushless powertrains so long as the spur and pinion pitch match and the drivetrain tolerances are correct.

How should I check gear mesh after fitting?

Fit the spur, install the pinion, then rotate the drivetrain by hand and inspect mesh pattern, adjusting pinion or shims until the contact sits centrally on the tooth faces.

Is this a good spare to carry to events?

Yes, carrying an extra 78T spur is sensible for events since gear damage can happen and a like for like replacement gets you back on track quickly.
