Mugen MRX-5 Front Axle Shaft Spring-Steel Upgrade by Arrowmax AM-MRX5-H0271  [AM-MRX5-H0271]

Front axle replacement for MRX-5

This component is an RC front axle shaft made for the Mugen MRX-5 1/8 chassis and supplied by Arrowmax as part AM-MRX5-H0271. It is the spring steel option intended for universal CVD use, delivered as a matched pair to replace or improve the MRX-5 front drivetrain.

The shaft is offered as a direct drivetrain replacement that focuses on long life and predictable flex under load. It functions as the torsional link between the CVD and hub, so correct alignment and fit are important to keep steering feel accurate and to prevent extra wear on neighbouring parts.

Fitting tips: check how the shaft seats in your existing universal/CVD assembly and confirm there is no binding across the full suspension travel. Reuse the original mounting hardware where appropriate and verify wheel runout and steering alignment after installation. Choose this spring-steel option when you want a tough shaft with controlled elasticity for front-end setup work.

MRX-5 owners looking for a reliable spring-steel front axle will find the Arrowmax AM-MRX5-H0271 delivers a good compromise of fatigue resistance and predictable torsional behaviour for tuning and replacement duties.
