Mugen MTX Ride-Height Lock Nut 7075 Hard by Arrowmax AM-MTX-H2704  [AM-MTX-H2704]

7075 hard adjuster built for MTX-5

This spring adjust nut is specified for Mugen MTX-5 use and is supplied by Arrowmax as AM-MTX-H2704. The 7075-grade construction noted in the product name gives a harder threaded element preferred by racers and tuners who change settings often.

Its role is to act as the threaded collar that sets coilover spring preload, enabling fine ride-height and corner-weight adjustments. It is typically used to lock a chosen preload rather than being treated as a consumable, so material choice matters for longevity when adjustments are routine.

Fitting is straightforward on compatible shock shafts: screw the nut onto the shock body or shaft to the required preload and then secure it. Verify the thread pitch and diameter match your shocks before tightening to prevent cross-threading and ensure reliable adjustment travel.
