Precision 48P 90T Spur Gear from 3Racing

The 3Racing 48 Pitch Spur Gear 90T, model number 3RAC-SG4890, delivers accurate tooth contact and steady performance for a wide range of RC vehicles. The 90 tooth arrangement promotes smooth torque flow and reduces the chance of sudden tooth failure under load.

Core Specification Overview

Tooth Count: 90T to spread torque and reduce stress per tooth
Pitch: 48P for compatibility with standard 48 pitch pinions
Material: Made to resist repetitive impacts and gear fatigue
Application: Useful for both competitive tuning and everyday repairs

How do I select the correct pinion for this spur?

Match pinion pitch to 48P and choose tooth count to achieve the desired gear ratio. Verify mesh and clearance once installed.

Are there any break in steps for a new spur?

Run a few light sessions to allow surfaces to bed in, then recheck mesh and fasteners. This helps the teeth seat evenly.

Can I use this spur with brushless setups?

Yes. It works with brushless motors provided the rest of your drivetrain is rated for the motor torque and speed.
