MTX-5 Engine Mount Nut - Arrowmax AM-MTX-H0704 for Mugen  [AM-MTX-H0704]

MTX-5 compatible engine nut

The Arrowmax AM-MTX-H0704 engine nut is an aftermarket part suited to Mugen MTX-5 applications, formed from spring steel to help maintain clamp force under vibration. It is intended to secure a nitro engine to the chassis flange and is marketed as an RC accessory rather than an original part.

Fit and compatibility: this nut is suitable for MTX-5 style engine mounts requiring a captive or mating nut and is intended to be used with compatible Mugen Seiki threaded interfaces. Prior to fitting, check thread condition, pitch and the seating face on both the engine and chassis to ensure correct engagement.

Installation and tuning: fit by aligning the engine flange and advancing the nut until a firm preload is achieved, then set final retention following your normal mounting routine. The spring steel helps preserve clamping through thermal change and vibration, aiding consistent engine positioning for tuning and track use.
