Mugen MTX-5 Hard Clutch Spring Upgrade by Arrowmax AM-MTX5-H0764  [AM-MTX5-H0764]

Performance spring for MTX-5 clutches

Arrowmax AM-MTX5-H0764 is a hard clutch spring made from spring steel and offered as an aftermarket hop-up for Mugen MTX-5 chassis. It replaces the factory spring to change the bite point and engagement feel in electric 1/8 scale cars.

Function and setup: the increased spring stiffness adds preload and produces a more positive engagement, useful where stock springs are too soft. Use this spring as part of a wider clutch tune that includes shoe profile, bell condition and gear mesh for balanced throttle response.

Fitting notes: shipped as a single spring component for the MTX-5 clutch pack; confirm fit and orientation before final assembly. Work cleanly, ensure the clutch bell rotates freely, and perform staged engagement tests to protect the drivetrain from shock loads.
