Mugen Seiki MTX-4 Rear Lower Aluminium Suspension Mount MTX4-45/TI by 3Racing  [MTX4-45/TI]

Machined rear lower aluminium mount

This aluminium rear lower suspension mount is a scale replacement part made for use with the Mugen Seiki MTX-4 chassis family. It functions as a direct replacement to support the rear suspension assembly and help preserve chassis geometry during routine maintenance and setup changes.

Use case centres on tuning and serviceability: the aluminium unit gives a firmer mounting point for the lower suspension arm at the rear, helping to maintain repeatable alignment and reducing slop compared with worn plastic mounts. It is suitable for track setup work and club-level practice sessions.

Installation tips: remove the original rear lower suspension mount from the MTX-4 chassis, compare mounting faces and screw positions, fit this aluminium piece into the same mounting points, and tighten fasteners by hand before final torque checks. Confirm arm articulation and wheel alignment during the first runs after fitment.
