Mugen MTX rear shock lower mount 7075 aluminium by Arrowmax AM-MTX-H2115  [AM-MTX-H2115]

7075 aluminium rear lower damper mount

The Arrowmax AM-MTX-H2115 rear lower damper stay is offered as an RC-scale replacement and upgrade for the Mugen MTX family, with particular reference to MTX-5 chassis arrangements. Supplied in a 2 pcs set, the component is CNC-machined from 7075 aluminium and intended for direct replacement of the rear shock lower mounting point.

Functionally the lower stay locates the bottom of the shock absorber and transmits loads into the rear bulkhead and suspension arms. Swapping the original stay for this 7075 item is a common step when changing shock types, replacing damaged mounts, or standardising geometry during setup sessions.

Installation tips: this is a chassis-level replacement that uses the existing lower damper mount points. When fitting, check that holes line up and threads engage correctly with the chassis and linkage hardware, re-check static droop and ride height once installed, and watch for any contact with adjacent parts. No full model fitting guide is supplied; use standard RC workshop practices.

Tuning benefits: the stiffer 7075 aluminium construction limits flex at the mounting point versus softer stock parts, which helps to keep shock alignment under load and makes small tuning changes to oil or spring rate more predictable.
