Mugen MTX Rear Knuckle Disc Pair (2) - MUGEN AM-MTX-T2129 by Arrowmax  [AM-MTX-T2129]

MTX rear upright disc for steering and alignment

This Arrowmax AM-MTX-T2129 product is supplied as a two-piece rear upright disc set intended for Mugen MTX chassis formats. The component serves as the rear steering knuckle and is offered as a direct spare or replacement for worn or broken uprights.

The upright disc affects rear steering input and wheel alignment when installed. It mounts between the rear hub/axle and the suspension links, so correct placement and secure fastening are necessary to maintain the original chassis geometry.

Fitting notes: perform normal disassembly of the rear hub and suspension and use common hobby tools like hex drivers and pliers. Trial-fit the disc to existing mounts before final torqueing, and check wheel rotation and alignment once fitted.

Tuning notes: changing upright discs is a straightforward repair or maintenance step to keep factory handling after impacts or extended running. Fit the AM-MTX-T2129 parts as like-for-like replacements to preserve handling characteristics.
