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.

Is this gear a direct replacement for stock spurs?

If your vehicle uses 48-pitch spurs, the 3Racing 3RAC-SG4879 will often fit directly, but confirm bore size and any mounting details first.

What pinion sizes pair well with 79T for track use?

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.

How do I check for wear on the spur teeth?

Inspect teeth surfaces for rounding or pitting and measure mesh clearance; replace the spur if tooth profiles are degraded.
