Compatible with Mugen MTX Rear Upright Disc Pair - MUGEN AM-MTX-T2129 Arrowmax  [AM-MTX-T2129]

Rear upright disc matched to MTX chassis

This Arrowmax AM-MTX-T2129 component comes as a two-piece rear upright disc set made for Mugen MTX chassis layouts. It functions as the rear knuckle connection and is intended as a direct spare or replacement when the factory disc is worn or damaged.

When fitted, these discs influence rear steer characteristics and camber alignment. The upright disc links the rear hub or axle assembly to the suspension link points, so correct orientation and seating are important to retain intended handling balance.

Installation advice: perform standard rear hub and suspension removal, then fit using common hobby tools such as hex keys and pliers. Confirm the new disc matches existing mounting points and verify wheel free-play and alignment after tightening fasteners.

Tuning advice: replacing upright discs is a simple maintenance or repair task to recover original chassis geometry after impacts or hard running. Use the AM-MTX-T2129 items to replace like-for-like and keep predictable rear-end behaviour.
