MUGEN MRX5 Spring Steel Inner Drive Joint Set AM-MRX5-H2213 by Arrowmax  [AM-MRX5-H2213]

Overview of the inner drive joint

The Arrowmax AM-MRX5-H2213 inner drive joint is a two-piece spring steel replacement made for the MUGEN MRX5 drivetrain. Provided as a matched pair, the parts are intended for routine replacement during maintenance or when changing internal drivetrain setup.

These joints connect driven shafts inside MRX5 differentials and axle assemblies, and are used to refresh worn components or try alternative fitments for tuning. Fitting requires removal of the relevant cover and basic RC disassembly and reassembly skills.

Maintenance advice: inspect the contact surfaces for wear and replace both pieces together to retain drivetrain alignment. After dusty or rough running, clear debris and ensure retaining screws are tightened to correct torque with threadlocker if applicable.

A practical spare for MRX5 owners performing drivetrain servicing or making setup adjustments that require spring-steel inner joints.
