Mugen MTX-5 rear lower damper stay (7075) - Arrowmax AM-MTX-H2115  [AM-MTX-H2115]

Rear lower damper mount in 7075 aluminum

This Arrowmax AM-MTX-H2115 rear lower damper stay is a scale replacement and hop-up made for Mugen MTX series cars, specifically matching MTX-5 chassis layouts. Supplied as a 2 pcs set, the part is machined from 7075 aluminum and intended as a direct swap or upgrade for the rear shock lower mounting point.

In service the lower damper stay positions the base of the shock and routes suspension loads into the rear bulkhead and control arms. Replacing the standard stay with this machined 7075 component is commonly done to retain alignment when changing shock assemblies, replace a worn mount, or lock in geometry during setup changes.

Installation notes: this stay fits the existing lower damper mounting locations on the chassis. During fitment check that hole alignment and thread engagement are correct, confirm ride height and static droop after refitting, and ensure there is no interference with nearby linkages. No full vehicle-level instructions are included; this is intended for RC model use only.

Tuning role: a 7075 aluminum lower damper stay reduces flex at the mount compared with typical stock materials, helping to keep shock geometry consistent under load. That stability supports repeatable damping adjustments when altering shock oil, spring selection, or mounting positions to tune rear balance and traction.
