Mugen MRX-5 Rear Drive Shafts Pair (Spring Steel) - AM-MRX5-H0291 by Arrowmax  [AM-MRX5-H0291]

MRX-5 rear driveshaft replacement

This pair of rear drive shafts is produced for the Mugen MRX-5 scale chassis and supplied as two pieces for axle rebuilds and routine maintenance. Manufactured from spring steel, the shafts balance torsional compliance with service life expected during club races and practice sessions.

Installation notes: install one shaft per side into the existing axle carrier and check clearance against the differential outdrive and wheel hub. Inspect spline engagement and tighten retaining hardware to the factory torque specification. The part is offered as a direct-fit spare/hop-up for MRX-5 assemblies and does not change suspension geometry.

Tuning role: spring steel rear shafts help preserve straight-line stability under drive and provide predictable flex on corner exit, making them a good choice for drivers looking for consistent traction without the added harshness of hardened alloys.

Fit these shafts when refreshing the MRX-5 rear drivetrain to recover even driveline behaviour; verify each shaft for straightness and secure spline fit during installation to ensure reliable operation.
