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

Rear upright disc for MTX chassis

This Arrowmax AM-MTX-T2129 item is an RC-scale rear upright disc supplied as a two-piece set, intended for use on Mugen MTX chassis layouts. The component functions as the rear steering/knuckle interface and is presented as a direct replacement or spare part where the original upright disc is required.

The part is intended to influence rear steering response and wheel alignment when fitted. In practice this means the upright disc serves as the mounting point between the rear hub/axle assembly and the suspension links, so attention to fit and orientation is important during reassembly to preserve intended geometry.

Installation notes: standard disassembly of the rear hub and suspension is required, and common hobby tools such as hex drivers and basic pliers are typically used. Verify fit against existing mounting points before tightening fasteners, and check wheel alignment and free rotation after installation.

Tuning role: swapping upright discs is a straightforward way to restore damaged parts or to maintain factory geometry after prolonged use, brake impacts, or ballistic loads during practice and racing. Use this part as a like-for-like replacement to retain known chassis behaviour.
