Action Clutch Safety Engineering:

Action Clutch’s patented fully enclosed spring retainer design addresses one of the most catastrophic failure modes in performance clutch systems — spring ejection. When clutch springs escape their retainers at high RPM, the results can be devastating to both the engine and transmission. Action Clutch’s enclosed design keeps springs contained at all times, protecting your drivetrain investment. Every kit is quality checked and signed off by Action Clutch engineers with over 60 years of collective experience before it leaves the facility.

Kevlar Friction Material:

The steel-backed segmented Kevlar friction disc offers a compelling combination of strength, heat resistance, and smooth engagement that makes it ideal for street/track builds. Kevlar’s high thermal tolerance means the disc maintains consistent friction characteristics under the heat generated by aggressive driving — without the harshness or noise associated with ceramic or metallic compounds. The segmented design improves heat dissipation further, extending disc life and maintaining engagement quality over time.

VQ37VHR Application:

The 3.7L VQ37VHR in the 2008–2013 Infiniti G37 is one of Nissan/Infiniti’s finest naturally aspirated engines — a high-revving, free-breathing V6 that responds exceptionally well to bolt-on modifications. As power increases through intake, exhaust, and tune upgrades, the factory clutch becomes the limiting factor. The Action Clutch Stage 2 kit provides the headroom needed for modified VQ37VHR builds while maintaining the street manners that make the G37 such a rewarding daily driver.

Why Action Clutch?

Action Clutch is a California-based performance clutch manufacturer known for application-specific engineering, rigorous quality control, and innovative safety features. Their clutch kits are designed for real-world performance use — not just dyno numbers — with a focus on longevity, drivability, and protecting the drivetrain components around them.

Perfect For:

• 2008–2013 Infiniti G37 owners with bolt-on modifications seeking a durable clutch upgrade
• Street/track builds requiring increased holding capacity without sacrificing daily drivability
• G37 owners experiencing clutch slip under hard acceleration
• Circuit, time attack, and road racing applications with occasional track use
• Anyone replacing a worn factory clutch and wanting a meaningful performance upgrade

Pro Tip: Replace or resurface the flywheel at the same time as the clutch for best results. A worn or heat-cracked flywheel will shorten the life of any new clutch kit.
