Mugen MTX Rear Upright Disc Set (2) - MUGEN AM-MTX-T2129 by Arrowmax  [AM-MTX-T2129]

Rear upright disc for Mugen MTX layouts

This Arrowmax AM-MTX-T2129 item is a two-piece rear upright disc designed for use with Mugen MTX chassis arrangements. The part acts as the rear steering knuckle interface and serves as a direct replacement or spare where the original upright disc is required.

Fitted upright discs affect rear steering feel and wheel alignment. The disc provides the mounting interface between the rear hub/axle assembly and suspension links, so careful orientation and fit during reassembly are important to preserve the chassis geometry you expect.

Installation notes: remove the rear hub and suspension in the usual way and use standard hobby tools such as hex drivers and pliers. Check the part aligns with existing mounting points before fully tightening fasteners, and confirm wheels spin freely and alignment is correct after installation.

Tuning role: swapping the upright discs is an effective way to replace damaged components or restore factory geometry after heavy use or impacts. Use this AM-MTX-T2129 assembly as a like-for-like replacement to keep your handling predictable.
