43.5mm M4 Shaft Matched to KIT-FFEX

The 3Racing FFEX M4 Shaft is produced at 43.5mm specifically for the KIT-FFEX chassis layout. It is a pragmatic replacement that helps restore drivetrain accuracy and reduces unwanted lash in the drive system.

Is this shaft suitable for competition use?

As a direct replacement it meets the original fitment specs. For high level competition you should inspect all related drivetrain parts and consider hardened or tuned components if required.

What should I pair this shaft with for best results?

Pair the shaft with good condition bearings and properly sized drive pins. A light service grease at contact points can reduce wear without affecting handling.

How do I confirm correct fitment after installation?

Check for free rotation without binding, minimal end play and smooth engagement under load. Any binding indicates incorrect seating or a damaged mating part.
