Mugen MTX Shock Preload Nut 7075 Alloy by Arrowmax AM-MTX-H2704  [AM-MTX-H2704]

High-hardness 7075 adjuster for MTX-5

This item is a spring adjust nut sized for Mugen MTX-5 shock assemblies, produced by Arrowmax under model AM-MTX-H2704. The use of 7075 material, as indicated in the name, provides a stiffer threaded contact surface useful when you tweak preload regularly.

The nut functions as the threaded collar that sets spring preload on coilover shocks, allowing incremental ride-height and balance adjustments. In tuning it acts to lock and fine-tune the preload rather than being a frequent replacement part, so alloy selection affects long-term service under repeated changes.

Installation is straightforward for matching shock shafts: screw the adjuster onto the shock body or shaft to the desired position and secure it. Confirm thread type and correct engagement before final assembly to avoid cross-threading and preserve adjustment smoothness.
