Race Oriented 48 Pitch 78T Spur from 3RACING

The 3RACING 48 Pitch Spur Gear 78T, catalog 3RAC-SG4878, is intended for tuners focused on gearing precision for 1/10 on-road platforms. It provides predictable tooth engagement for consistent lap to lap behaviour.

Tuning Flexibility for Competitive Builds

As a 78T 48 pitch component, this spur lets racers make fine adjustments to overall ratio without large jumps in gear ratio. That precision aids in finding the best compromise between acceleration and terminal speed for each circuit.

Value Racing Part with Consistent Performance

Produced to maintain stable mesh under typical race loads, the spur offers a balance of durability and cost effective replacement. It is a practical choice when setting up multiple cars or keeping spares for event days.

What pinion pitch should pair with this spur?

Use a 48 pitch pinion that matches your desired tooth count; ensure pinion diameter and shaft fit are compatible with your gearbox to maintain correct mesh.

How do I fine tune gear ratio for qualifying versus main?

Adjust pinion tooth count in small steps while keeping the 78T spur; test lap time and throttle response to pick the best setup for qualifying and the race.

Are there common failure points to inspect?

Check for tooth wear, burrs, and consistent mesh pattern after each event. Replace if teeth show flattening or if the mesh shifts under load.
