MUGEN MRX5 Inner Drive Joint (spring steel) for MRX5 - AM-MRX5-H2213 by Arrowmax  [AM-MRX5-H2213]

Compact MRX5 drivetrain overview

This Arrowmax AM-MRX5-H2213 inner drive joint is supplied as a two-piece, direct-fit replacement for the MUGEN MRX5 drivetrain. Manufactured from spring steel, it is intended for use where inner joints are serviced or swapped during routine maintenance and tuning sessions.

The component links driven shafts inside the differential and axle assemblies on the MRX5, and is fitted when worn joints are refreshed or when trying alternate fitments as part of setup changes. Fitting normally requires basic removal of the relevant axle or differential cover and standard RC workshop practice.

Care and inspection: check the mating surfaces for wear or deformation and always replace in matched pairs to maintain consistent drivetrain geometry. Remove trapped grit after off-road running and apply correct thread locking and torque to any retaining screws per your service routine.

Keep a set of these spring-steel inner joints on hand for MRX5 drivetrain servicing and straightforward setup swaps.
