MUGEN MRX5 Spring Steel Rear Axle Shafts - AM-MRX5-H0277  [AM-MRX5-H0277]

Durable spring steel rear axle for universal drives

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 unit is supplied as a shaft element for universal joints rather than a full-length driveshaft assembly. It acts as a replaceable wear component in the rear drivetrain and is selected when builders want a firmer, less permanently bent shaft over softer steel variants, or when aligning material properties during a rebuild.

Fitting guidance: insert the shaft into the universal drive assembly and secure with the model's normal retention method. Check for axial play and smooth rotation during trial assembly, and ensure alignment with the differential and gearbox to reduce premature wear. Inspect for surface damage after extended runs.

Fit these spring steel shafts when you need a tougher replacement that works with universal drives and MUGEN MRX5 compatible assemblies; consider trade-offs with 7075 aluminium for weight versus stiffness in your setup.
