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. Below are practical notes on fitment, safe handling during installation, and how these bushes contribute to stable suspension geometry without claiming unspecified material properties.

Replacement advice: fit this set to remove play or after repairing front suspension components to restore accurate pivot alignment. The bushes fit into the front upper arm mount area and affect pivot geometry; inspect the arms and mounting bores for wear before installing new parts. Work with the chassis secured and follow your usual disassembly sequence to avoid damage.

Handling and tuning: correctly fitted bushes keep articulation consistent and alignment repeatable across sessions, which aids predictable handling when you test setup changes. When adjusting camber or toe using upper arm position, check bush seating and lateral clearance during your setup routine.
