MUGEN MBX Replacement F/R Cup Joint Spring Steel - AM-MBX-E0228 by Arrowmax  [AM-MBX-E0228]

Function and recommended use

The Arrowmax AM-MBX-E0228 F/R Cup Joint is an aftermarket replacement part intended for MUGEN MBX chassis. Fabricated from spring steel, it operates as both front and rear cup joints linking steering and drive rods. The description focuses on accurate fit, proper installation, and the influence on tuning rather than performance claims.

Fit and function: this cup joint is suitable where worn ends cause sloppy steering or misaligned drivetrain geometry. Installing the part restores correct linkage positions and helps keep handling predictable during setup and track work.

Installation notes: inspect mating pins and turnbuckles for wear before fitting. Fit the cup over the pin with the right clearance, then check full suspension travel and steering sweep for any binding. Adjust turnbuckle lengths or angles as needed to maintain original alignment.

Use these spring-steel cup joints as a dependable like-for-like replacement when repairing MBX linkage geometry or upgrading to tougher maintenance hardware.
