Competition oriented 48 pitch pinion for tuning accuracy

The 3Racing 48P 50T Pinion Gear is produced from 7075 aluminium and finished with a hard coating to enhance resistance to wear while keeping gear mesh consistent under racing conditions. Its construction supports repeatable setup changes and dependable engagement across multiple runs.

Technical notes for setup and tuning

Using a 50-tooth pinion gives tuners fine control over final drive steps in 48 pitch systems. When adjusting ratios, monitor motor temperatures and check mesh after initial run-in. The hard coated surface helps maintain tooth profile integrity during extended use.

What checks should I perform after installing the pinion?

Verify shaft fit and grub screw torque, set correct mesh with a brief controlled run-in, then recheck for any movement. Confirm no abnormal noise or binding under load before full race conditions.

How does tooth count affect gearing strategy?

Each tooth change shifts the final ratio and affects acceleration versus top speed. Use the 50T as a middle ground and make incremental changes to tune for track layout and motor characteristics.

Any recommendations for maintaining wear resistance?

Keep the pinion clean, ensure correct backlash and use consistent lubrication on the spur when appropriate. Regular inspections will catch early wear and preserve the hard coated surface performance.
