Reliable Spur Gear for Tuning and Control

The 3Racing 48 Pitch Spur Gear 91T, identified as 3RAC-SG4891, is a practical option for those adjusting drivetrains to suit different tracks. It is built to fit common 1/10 configurations and aims to provide steady engagement under varied load.

Consistent Torque Distribution

With 91 teeth, this spur helps moderate torque delivery so power is transferred smoothly through the transmission. That steadiness helps when switching between fast sections and tight bends.

Simple Fitment for 1/10 Builds

Made for broad compatibility across 1/10 models, the gear responds well to pinion swaps and ratio testing. Always confirm clearance and mesh to avoid premature wear.

Can I use this with stronger motor setups?

You can, but check the rest of your driveline and ensure gear mesh and motor torque are matched to avoid overstressing components.

Will it change my top speed a lot?

A higher tooth count will tend to favour torque and acceleration control, which can reduce top end slightly depending on your pinion choice.

Any tips for installation?

Set a proper backlash, ensure the spur runs true on the shaft, and verify there is no rubbing on the chassis or nearby parts before final runs.
