Robust 48 pitch pinion made for regular track use

Fit the 3Racing 48P 50T Pinion Gear to add strength to your drivetrain. Fabricated from 7075 aluminium and finished with a hard coat, it helps limit tooth wear so gear performance stays consistent during repeated runs.

How this pinion helps your setup

The 50-tooth size gives useful granularity when adjusting final drive ratio in 48 pitch systems. Its broad fitment range makes it easy to incorporate into many cars when you want predictable gearing behaviour.

Do I need a new spur gear with this pinion?

Not necessarily. Use a compatible 48 pitch spur and check mesh and backlash. Replace the spur only if it shows wear or if changing tooth counts creates interference.

Is the 7075 alloy better than standard aluminium?

7075 aluminium is a higher strength alloy that, when hard coated, increases resistance to deformation and wear compared to softer aluminium grades commonly used in hobby parts.

How do I check correct gear mesh?

Fit the pinion and spur, set a small amount of backlash, then rotate the drivetrain by hand while checking for smooth engagement. A thin paint or gear mesh gauge can help set the ideal clearance.
