Arrowmax AM-MRX5-H2105 Mugen MRX5 Front Lower Arm Shaft - Spring Steel Upgrade  [AM-MRX5-H2105]

Performance Upgrade for Mugen MRX5 Suspension

Made for the Mugen MRX5, the Arrowmax AM-MRX5-H2105 front lower arm shaft is manufactured from durable spring steel to handle track stresses while keeping movement smooth. The titanium nitride surface treatment reduces friction and boosts service life without changing the original geometry.

Advantages of a Low-Friction Coating

The titanium nitride finish on these shafts lowers sliding resistance and helps prevent surface wear, so pivot action stays consistent over many runs. That reliability is useful for racers and club drivers alike who want predictable suspension response.

Exact Fitment for MRX5 Chassis

These shafts are precision made to drop into the Mugen MRX5 front arms with no extra machining required, replacing worn originals for immediate handling improvements.
