Mugen MRX-5 Front Upper Arm Mount Bush Set - Arrowmax AM-MRX5-H2120A  [AM-MRX5-H2120A]

Front upper arm bushes for MRX-5 fitment

This bush set is a scale RC accessory intended for the front upper arm mount of Mugen MRX-5 chassis, supplied under Arrowmax part AM-MRX5-H2120A. The following notes focus on fitment guidance, practical installation steps, and the functional role of the bushes without asserting unverified material claims.

Fitment and service: install this set when bushes show play or after repairing suspension components to restore correct pivot seating. The parts sit directly at the front upper arm mount and influence pivot alignment, so inspect the arms and mount points for wear prior to fitting. For safety, secure the chassis before you work and follow your model's standard disassembly sequence.

Tuning notes: correctly seated bushes preserve consistent articulation and alignment through repeated runs, which helps keep handling predictable during setup changes. When you alter camber or toe via upper arm geometry, verify bush seating and clearance as part of routine setup checks.

For MRX-5 owners replacing front upper arm bushes, the Arrowmax AM-MRX5-H2120A is a direct-fit option aimed at restoring mounting precision and supporting suspension setup tasks.
