Performance upper arm mount for MRX5

This front upper arm mount plus bush set is made for the Mugen MRX5 front suspension and gives a direct way to tweak chassis geometry. The component is machined from 7075-T6 aluminium and includes adjustable POM inserts that allow roll centre adjustments without swapping out the rest of the suspension. The following notes focus on fitment, construction, and tuning implications for club and circuit running.

Fit this mount when you want crisper front-end response; the POM inserts let you move the upper arm pivot in small steps to influence turn-in and load transfer. Installation uses the MRX5 front arm mounting points and the existing stock fasteners for a clean upgrade path.

Specifications

  • Item: Front upper arm mount with bush set
  • Material: 7075-T6 aluminium, POM inserts
  • Model Number: AM-MRX5-H2120
  • Compatibility: Mugen MRX5

An aluminium-based upgrade for Mugen MRX5 users who want to refine front geometry and roll centre without major chassis work.

Does this require new ball studs or hardware?

No new ball studs are normally needed; the mount is designed to accept the MRX5 stock hardware. Verify hardware condition and torque settings when refitting.

Can this help with understeer on entry?

Fine adjustments to the roll centre can alter front grip behaviour. Lowering or shifting the pivot slightly may improve initial turn-in and reduce mild understeer, but test changes one step at a time.

Are replacement POM inserts available?

Replacement or spare POM inserts are recommended for long-term use; check with your parts supplier for genuine Arrowmax spares to maintain correct fitment.

Will aluminium contact wear affect adjustability?

7075-T6 aluminium is durable, but inspect interfaces regularly. The POM inserts take most wear; replacing worn inserts keeps adjustment locations precise.
