MUGEN MRX5 front upper arm mount with bush set 7075-T6 by Arrowmax AM-MRX5-H2120  [AM-MRX5-H2120]

Front upper arm mount for MRX5

This front upper arm mount with bush set is made for the Mugen MRX5 front suspension and provides a direct upgrade path for chassis geometry adjustment. Machined from 7075-T6 aluminium, the part includes adjustable POM inserts that let builders tune roll center position without replacing other suspension components. The description and details below focus on fit, material, and tuning role on RC-scale setups.

Use this mount when you need more precise control over front suspension geometry; the POM inserts allow small incremental changes to roll center that can affect turn-in and weight transfer in track tuning. Installation follows standard front arm mounting points on the MRX5 chassis and uses the existing hardware from the stock mounts.

This component is a direct, material-upgrade option for Mugen MRX5 users who want to refine front-end geometry and roll center without major chassis modification.
