Engineered Spur Gear for Balanced Drive

RC drivers looking for predictable drivetrain behavior will value the 3Racing 48 Pitch Spur Gear 79T. Its 48-pitch tooth spacing and 79-tooth count offer a compromise between acceleration and top speed, useful across a variety of on-road and off-road models.

Why Hobbyists Choose This Gear

  • Consistent Engagement: The 48-pitch design from 3Racing helps maintain steady contact between pinion and spur.
  • Flexible Fitment: Compatible with many kits and aftermarket gearboxes that accept 48-pitch components.
  • Serviceable: Suitable for repeated tuning and routine gearbox servicing.
  • Practical Upgrade: Ideal when adjusting final drive or replacing a worn spur during preparation for a race day.
If your vehicle uses 48-pitch spurs, the 3Racing 3RAC-SG4879 will often fit directly, but confirm bore size and any mounting details first.
Typical choices depend on motor Kv and track layout; use smaller pinions for tight tracks and larger ones for long straights to tune top speed.
Inspect teeth surfaces for rounding or pitting and measure mesh clearance; replace the spur if tooth profiles are degraded.
