Accurate 48 Pitch Spur for Tuned Setups

Hobbyists aiming for smoother throttle response will find the 3Racing 48 Pitch Spur Gear 85T a useful upgrade. It suits a range of common RC chassis where precise gear engagement matters for on-track consistency.

Core Features and Fitment

Tooth Count: 85T to boost torque delivery and make modulation easier.
Pitch: 48 pitch for matching with standard pinions used in many kits.
Material: Manufactured to tolerate regular use and typical racing stresses.

When to Fit This Spur

Choose this spur when adjusting gear ratios for better acceleration out of corners or when you need a reliable replacement during race day maintenance. The accurate teeth help reduce driveline noise and maintain traction.

Can I use 3RAC-SG4885 with brushless motor systems?

Yes, the spur gear itself is compatible with brushless or brushed drivetrains; ensure the pinion gear matches the pitch and motor spacing is correct.

Does the 85T option affect battery strain?

Higher tooth count typically increases torque demand at lower speeds, which can draw more current under heavy acceleration. Monitor temperatures and gearing for battery life.

Is any break-in needed for new spur gears?

Light running under low load for a few minutes helps settle the mesh. Check for even wear and retighten hardware after initial sessions.
