Simple Upgrade with the 3RACING 48 Pitch 78T

The 3RACING 48 Pitch Spur Gear 78T, reference 3RAC-SG4878, offers a reliable way to alter gearing on 1/10 scale on-road models. It is designed for straightforward fitting and steady drivetrain operation during club meets.

Adjustable Ratio Options

The 78-tooth layout gives modelers fine control over final ratios, useful when testing different pinions to find the best balance for acceleration and top speed on local tracks.

Hard-Wearing for Regular Use

Manufactured with durability in mind, this spur stands up to frequent running while keeping gear mesh stable. It is a sensible upgrade for hobbyists who run often and want consistent performance.

Is this compatible with belt or shaft driven setups?

This spur is for gearbox style spur and pinion systems typical of on-road 1/10 cars; belt driven layouts use different components.

What pinion range works well with a 78T spur?

Good pinion choices depend on motor and track, but many users test mid to high tooth pinions to dial in acceleration versus top speed trade offs.

How often should I inspect the spur?

Check for wear and proper mesh after a few runs and then as part of regular maintenance, especially if you run hard or in dusty conditions.
