Track Ready 48 Pitch 39T Pinion from 3Racing

The 3Racing 3RAC-PG4839 pinion is produced from 7075 aluminum to keep rotating mass low while maintaining strength. The hard coating provides enhanced wear resistance so it stands up to repeated tuning and testing sessions.

Performance and Compatibility Notes

Designed for 48 pitch systems, the 39 tooth count lets you tweak gear ratios to suit loose or prepared surfaces. The coated finish helps reduce friction and extend service life, aiding smoother starts and cleaner gear engagement.

What should I check before fitting this pinion?

Check the bore size, set screw position and mesh with your spur gear. After mounting the 3Racing 3RAC-PG4839, confirm mesh and run a few slow tests before full throttle runs.

Will this pinion change my vehicle handling?

Altering pinion tooth count changes acceleration and top speed. Moving to a different tooth count with the 3Racing 3RAC-PG4839 will shift power delivery but not directly change suspension or steering behaviour.

How can I maximize gear life?

Keep mesh set correctly, avoid misalignment, and inspect the pinion and spur for wear. The hard coating on this 7075 part helps, but routine checks will extend service life.
