Race oriented drivetrain behaviour with the 3Racing 73T spur

For competitive setups where repeatable gear mesh is essential, the 3Racing 48 Pitch Spur Gear 73T Ver.2 offers predictable engagement and serviceable durability. It is suitable for fine tuning gear ratios and setup changes on track-focused vehicles.

Technical highlights for racers

  • Tooth Count: 73T to influence final drive ratio and torque feel
  • Pitch: 48 pitch for direct compatibility with common 48 pitch pinions used in racing
  • Durability: Manufactured to provide consistent running under frequent tuning and track use

How should I set gear mesh for optimal racing performance?

Aim for a close, even mesh with minimal backlash; validate under load at low speed and recheck after initial runs to avoid premature tooth wear.

What pinion choices pair well with this 73T spur?

Select pinion sizes based on desired acceleration versus top speed; small changes in pinion teeth will shift the balance without altering spur durability.

Any race day maintenance to keep this gear reliable?

Carry a spare, inspect mesh and grub screws between heats, and clear debris from the gearbox to maintain consistent lap times.
