Mugen MTX-5 Clutch Spring Hard (spring steel) by Arrowmax AM-MTX5-H0764  [AM-MTX5-H0764]

Hard clutch spring for MTX-5

This Arrowmax AM-MTX5-H0764 is a hard clutch spring made from spring steel, produced as a scale accessory for Mugen MTX-5 applications. It is intended as a direct-replacement hop-up spring to alter clutch engagement characteristics on Mugen MTX chassis in electric RC setups.

Role and tuning: the harder spring increases preload and raises engagement firmness, helping drivers dial in quicker or more positive engagement where stock springs feel too soft. Use it as one element in clutch tuning alongside clutch shoes, bell condition, and gear mesh adjustments to achieve the desired throttle response.

Installation notes: this part is supplied as a single spring component for fitting into the MTX-5 clutch assembly; confirm fit and orientation against the existing spring before final assembly. Work on a clean bench, verify free movement of the clutch bell, and test engagement progressively to avoid overloading the drivetrain.
