Product Description

The ACT ZM14-HDG6 is a Heavy Duty Race Sprung 6-Pad clutch kit built specifically for the 2019-2025 Mazda MX-5 Miata. It pairs ACT's Heavy Duty pressure plate - with its four-stage heat-treated diaphragm and precision cover stamping - with a 6-pad, spring-centered race disc designed to shed heat quickly while damping torsional vibration through the driveline.

This setup is intended for MX-5 owners who want faster shift response and a firmer, race-oriented engagement over a stock or street-disc clutch, while retaining a sprung hub for reasonable street manners. Unlike many ACT kits for this platform, this one includes a matched ACT flywheel, simplifying the installation into a single, complete package rather than requiring a separate flywheel purchase.

Every ACT clutch assembly is newly manufactured (not rebuilt) and computer spin-balanced to within .25 oz-in for reliable operation at high RPM, making this kit a solid fit for MX-5 owners running increased power who need more torque-holding capacity than the factory clutch provides.
