MTX-5 Spring Seat Upgrade 7075 HARD - Arrowmax AM-MTX5-H2703  [AM-MTX5-H2703]

Durable MTX-5 Spring Cup 7075 HARD

This Arrowmax AM-MTX5-H2703 spring cup is an RC replacement component built for Mugen MTX-5 shock assemblies, CNC-machined from 7075 aluminium to provide a harder contact surface than standard alloys. It functions as the spring seat that locates and secures the shock spring on the shaft, helping maintain consistent spring position and predictable suspension behaviour during setup and tuning.

Fit and purpose: the part is made for MTX-5 compatible shock platforms and fits as a direct replacement or an upgrade where the original plastic or softer metal seat is installed. The 7075 hard alloy reduces wear at the spring contact point and keeps spring indexing stable over repeated runs, which is helpful when you are iterating ride height and damping settings.

Installation notes: check mating surfaces for burrs or grit before assembly, slide the cup onto the shock shaft to confirm smooth movement, and refit using the original retaining hardware with recommended torque. Do not force misaligned parts, and re-check spring preload and free length after installation to confirm expected suspension response.
