Race oriented notes for the 3RACING 48 Pitch Spur Gear 85T

The 3RACING 48 Pitch Spur Gear 85T provides a consistent plastic option for setups that prioritise weight savings and easy servicing between heats. It offers predictable engagement for teams that need quick spur swaps during event maintenance.

Performance and setup considerations

When tuning for competition, ensure correct gear mesh and inspect the spur for wear after sessions. The plastic construction helps protect pinions and can reduce secondary damage to the gearbox under moderate impacts.

Tuning and upgrade advice

Use the 85T as a baseline part for testing pinion sizes and gear ratios; its low cost makes it useful for trial runs before committing to hardened gears for higher power or long term durability.

How should I set gear mesh for competition use?

Set a fine but visible gap between pinion and spur, rotate the drivetrain to proof run, then tighten mounts and confirm there is no binding under load.

Is this spur suitable for tuning through multiple heats?

Yes, its low replacement cost makes it suitable for iterative setups during race weekends, but consider metal spurs if you consistently run high torque or very aggressive pinion choices.

What inspection points matter most after each run?

Check for tooth rounding, cracks and uneven wear, confirm hub fixation is tight and inspect mating pinion for nicks that can accelerate wear.
