Drivetrain Upgrade for Improved Efficiency

The 3Racing 48 Pitch Spur Gear 91T, model number 3RAC-SG4891, is a straightforward upgrade for RC hobbyists aiming to sharpen drivetrain efficiency. It is made to sit cleanly in standard 1/10 transmissions and deliver consistent tooth engagement for dependable operation.

Street and Track Performance

This 91-tooth spur balances torque distribution to help maintain stability during fast laps or longer runs. Its tooth profile supports smooth power delivery, useful for drivers who swap ratios between speed and acceleration setups.

1/10 Scale Fitment and Tuning

Designed for a broad range of 1/10 scale applications, the gear integrates with common pinions and mounting arrangements. Hobbyists who fine tune gear ratios will find it simple to test different setups for improved handling or top speed.

Will this spur fit my 1/10 electric car?

It fits the majority of 1/10 transmissions, but confirm your pinion pitch and shaft spacing before purchase to ensure correct mesh and clearance.

How does a 91T spur affect performance?

A larger tooth count like 91T shifts the balance toward torque and smoother acceleration, which can improve traction and control at the expense of some top speed.

What should I check after installing the spur?

Inspect gear mesh for even contact across the tooth faces, check for any binding, and verify the spur spins freely under load before full runs.
