MRX5 inner joint summary

The Arrowmax AM-MRX5-H2213 inner drive joint is a two-piece spring steel replacement specifically intended for the MUGEN MRX5 drivetrain. It is supplied for routine maintenance tasks and for users who swap inner joints during setup adjustments.

Functionally, this part joins driven shafts inside the differential and axle areas on the MRX5 and is used when replacing worn links or exploring different fitments during tuning. Installation involves basic disassembly of the affected axle or differential section and standard RC workshop procedures.

Upkeep tips: examine mating faces for scoring or deformation, fit replacements as matched pairs to preserve drivetrain alignment, clear debris after rough-surface running, and secure fasteners with the correct torque and threadlocker as required.

Use this spring-steel inner joint set when performing MRX5 drivetrain service or when changing internal components during setup work.
