Mugen MRX-5 Rear Upper Arm Mount A - Arrowmax AM-MRX5-H2113  [AM-MRX5-H2113]

Rear upper arm mount suited to MRX-5 setups

The Arrowmax AM-MRX5-H2113 rear upper arm holder is built for the Mugen MRX-5 chassis and serves as the attachment point for the rear upper suspension arm. Its position directly affects rear suspension geometry and the alignment of associated linkages.

Fitting is straightforward for experienced tuners: remove the factory holder, check mating faces and fastener sizes on your MRX-5, and generally reuse the original screws unless the chassis manual specifies otherwise. After trial fitting, inspect left-to-right symmetry and verify full travel of suspension and driveline before final torque.

From a setup perspective the component determines the upper arm pivot location and therefore impacts roll centre and camber change. Swapping A/B style holders or shifting the mount should be done in small steps with test runs to judge rear-end balance and traction changes.
