MUGEN MRX5 Universal Rear Axle Shafts (pack of 2) - AM-MRX5-H0277  [AM-MRX5-H0277]

Rear axle shaft, spring steel construction

This Arrowmax AM-MRX5-H0277 item is a spring steel rear axle shaft supplied as a pack of 2 pcs for RC-scale drivetrains. It targets universal-style drives and is listed alongside MUGEN MRX5 chassis parts, offering an option where higher elastic recovery and fatigue resistance from spring steel are preferred for repeated loading in on-track tuning and maintenance.

The component is intended as a direct shaft element for universal joints and not as a full driveshaft assembly. It serves as a replaceable wear part in the rear drivetrain, selected when operators want a stiffer, less permanently deforming shaft compared with softer steel options, or when matching material attributes during rebuilds.

Assembly notes: the shaft fits into the universal drive assembly using the model's standard retention method. On fit-up check for axial play and unobstructed rotation before completing reassembly, and confirm alignment with the differential and gearbox to reduce premature wear. Inspect for surface damage or burrs following intensive use.

Opt for this spring steel shaft when you require a robust replacement that integrates with universal drives and MUGEN MRX5 related layouts; weigh the differences between spring steel and 7075 aluminium for your tuning priorities around stiffness and mass.
