Mugen MTX-5 Spring Steel Engine Nut Upgrade by Arrowmax AM-MTX-H0704  [AM-MTX-H0704]

Engine mount nut for MTX-5 setups

Arrowmax AM-MTX-H0704 is an aftermarket spring steel engine nut intended for Mugen MTX-5 style chassis, produced to retain clamping under vibration common in off road RC. It secures the nitro engine flange to the chassis and is supplied as an accessory part.

Compatibility guidance: the nut is made for MTX-5 style mounts that require a captive or mating nut and is intended to work with matching Mugen Seiki threaded interfaces. Verify thread condition, pitch and the seating face on both engine and chassis before final assembly.

Fitting and tuning notes: install by aligning the engine flange and running the nut down until a firm preload is achieved, then finish tightening to your normal mounting routine. The spring steel construction helps keep clamp force through heat cycles and vibration, which aids stable engine positioning during tuning and rough running.
