Track-Proven Arm Shaft for Mugen MRX5

The Arrowmax AM-MRX5-H2105 front lower arm shaft is engineered for the Mugen MRX5, using resilient spring steel to cope with aggressive driving while smoothing suspension movement. The titanium nitride treatment cuts sliding friction and prolongs the component's service life.

Coating Benefits Explained

The titanium nitride layer adds a hard, low-friction surface that limits wear on the shaft, helping maintain consistent steering feel and reducing the chance of binding under load.

Drop-In Fitment for MRX5 Chassis

Made to the original dimensions for the Mugen MRX5, these shafts swap in easily for worn originals and restore reliable pivot action without setup changes.
