Setup-Focused Spur Gear for Tuned Drivelines

The 3Racing 64 Pitch Spur Gear 124T is aimed at racers and serious tuners who require consistent, predictable changes in final drive. The 124 tooth count lets you refine gear ratios in smaller increments, aiding in fine tuning acceleration, motor load, and top speed trade offs for competitive runs. Check mesh and matching pinion choices when integrating this spur into a race setup.

What setup checks are critical when fitting 3RAC-SG64124?

Verify correct mesh across the full rotation, ensure pinion and spur are both 64 pitch, and confirm carrier bearings and mount bolts are torqued to spec to prevent movement under load.

Which tuning goals benefit most from a 124T spur?

Use the 124T spur when you need smaller incremental ratio shifts to balance acceleration versus top speed, or to fine tune motor RPM in specific track sections.

Any race day advice when using this spur gear?

Bring spare pinions, recheck mesh after practice runs, and monitor motor temperature since small ratio changes can affect motor load during long heats.
