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

Rear upright disc tailored for MTX chassis

This Arrowmax AM-MTX-T2129 unit is supplied as a pair of rear upright discs for Mugen MTX chassis layouts. The assemblies act as the rear steering knuckle interface and are intended as direct replacement parts when originals are damaged or worn.

When installed, upright discs have a direct effect on rear steering responsiveness and wheel alignment. They connect the rear hub or axle to suspension links, so correct seating and orientation are vital to preserve the design geometry of the chassis.

Fitting guidance: remove the rear hub and associated suspension items in the normal manner and fit using ordinary hobby tools such as hex drivers and pliers. Confirm the AM-MTX-T2129 aligns with your mounts before final tightening, then verify wheel rotation and alignment.

Practical tuning use: replacing the uprights is a simple way to restore original geometry after impacts or heavy running. Install these parts as like-for-like spares to keep the known handling balance of your model.
