Race-oriented spur shaft tuned for FGX Evo drivetrains

The 3Racing FGX-125 spur gear shaft is developed to deliver consistent torque transmission with tight tolerances suitable for tuned FGX Evo rigs. Its construction supports reliable gear engagement under sustained racing loads.

Performance considerations for setup

Installers should verify mesh and backlash when fitting the FGX-125 to avoid premature wear. The shaft integrates with standard FGX Evo layouts and is intended to improve drivetrain consistency for lap-to-lap predictability.

  • Compatibility: Direct fit for FGX Evo chassis configurations
  • Durability: Specified to withstand competitive running conditions
  • Precision: Reduces drivetrain variability for tighter handling feedback

What should I check during installation?

Verify proper mesh, axial alignment and secure fastenings. Small adjustments to pinion spacing can significantly affect engagement and noise.

Any recommendations for high-power tuning?

When increasing motor power, review related drivetrain components and consider incremental testing to ensure the shaft and mating gears tolerate the added load.

How to monitor shaft wear?

Inspect contact surfaces and run-in patterns regularly. Any irregular wear or scoring on mating surfaces indicates the need for re-evaluation of mesh and component compatibility.
