Mugen MTX Spring Adjust Nut 7075 Hard Alloy by Arrowmax AM-MTX-H2704  [AM-MTX-H2704]

7075 alloy spring adjuster for MTX-5

This spring adjust nut is designed for use with Mugen MTX-5 style shocks and is produced by Arrowmax as model AM-MTX-H2704. The 7075 alloy noted in the name provides a harder threaded surface chosen for its durability under repeated adjustments.

The unit serves as the threaded collar that establishes spring preload on coilover shocks, enabling incremental ride-height and corner-balance changes. It is used to lock and fine-tune preload settings rather than as a part expected to be regularly replaced, making material selection important for long-term reliability.

Installation is direct for matching shock shafts: screw the adjuster onto the shock body or shaft to the target preload and then secure it in place. Always verify thread compatibility and engagement before final assembly to prevent cross-threading and ensure predictable adjustment travel.

Compatibility details
