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

Rear lower aluminium bracket for MTX-4

This aluminium rear lower suspension mount is a replacement part intended for the Mugen Seiki MTX-4 chassis family. It fits as a direct swap to support the rear suspension and maintain intended chassis geometry through routine maintenance or adjustments.

Designed with setup and repeatability in mind, the part provides a rigid attachment for the rear lower arm, which helps reduce movement compared to ageing plastic mounts and assists with consistent alignment when changing settings. It is ideal for club racing and track practice where reliable geometry matters.

Fitting advice: remove the stock rear lower mount, check that screw locations match the MTX-4 chassis pattern, install this aluminium unit using the same fasteners, and secure hardware to a conservative hand-tight level before final verification. Re-check wheel alignment and suspension travel after installation.
