MRX5 Front Upper Arm Mount 7075-T6 Upgrade - MUGEN AM-MRX5-H2120 by Arrowmax  [AM-MRX5-H2120]

Precision front upper arm mount for MRX5

This front upper arm mount with bush set is built for the Mugen MRX5 front suspension and offers a straightforward upgrade path to refine chassis geometry. Machined from 7075-T6 aluminium, the unit includes adjustable POM inserts that let builders alter roll center position without swapping out major suspension parts. The notes below cover fitment, materials, and tuning impact for RC track setups.

Fit this mount when you need finer front suspension control; the POM inserts permit small, repeatable shifts to the upper arm pivot that can change turn-in and weight transfer during track tuning. Installation uses the MRX5's standard front arm mounting points and reuses the stock hardware for a clean swap.

This part is a direct material upgrade for Mugen MRX5 owners who want to fine-tune front-end geometry and roll center without heavy chassis modifications.
