Racing Oriented Spur with Controlled Backlash

The 3Racing 48 Pitch Spur Gear 74T Version 2 is produced with tight manufacturing tolerances to promote even tooth contact and consistent torque transfer during competitive use. It is intended for tuners seeking predictable gear ratios and reliable mesh under racing loads.

Technical Highlights for Tuning

  • Pitch: 48
  • Tooth Count: 74T
  • Compatibility: Suits popular 48 pitch race chassis and modifications
  • Durability: Built to maintain dimensional accuracy over multiple sessions

What mesh tolerance should I target for race trims?

Aim for a slight, even contact pattern across the tooth face with minimal play at rest to balance efficiency and durability during heats.

How does tooth count affect gearing choices for sprint formats?

A higher tooth count like 74T favours smoother acceleration and refined top end control; adjust pinion to suit track layout and motor characteristics.

Are there tuning tips to reduce drivetrain losses with this spur?

Keep bearings in good condition, set correct pinion mesh, and use a light lubricant on contact faces to minimise parasitic losses while preserving grip.
