MUGEN MBX Front/Rear Cup Joint (spring steel) - AM-MBX-E0228 by Arrowmax  [AM-MBX-E0228]

Purpose and chassis compatibility

The Arrowmax AM-MBX-E0228 F/R Cup Joint is a direct replacement linkage end made for use on MUGEN MBX chassis. Manufactured from spring steel, it functions as both front and rear cup joints to connect steering and drive linkages, and the text below explains fit, installation considerations, and tuning implications without exaggerating capability.

Fit and function: this cup joint replaces worn or damaged linkage ends that degrade steering feel and drivetrain geometry. As a like-for-like replacement it helps restore original linkage positions and gives predictable behaviour during setup and on-track tuning sessions.

Installation notes: inspect mating pins and linkages for wear before fitting, slide the cup over the pin with appropriate clearance, and confirm free movement through suspension travel and steering throw. Minor turnbuckle adjustments or linkage angle tweaks may be needed after installation to regain correct alignment.

Fit these cup joints when restoring MBX linkage geometry or when you want a durable spring-steel replacement for routine maintenance and setup work.
