ACT Xtreme Duty Performance Street Disc Clutch Kit – Mitsubishi Models (inc. 1990-1999 Eclipse Turbo)

ACT ACT Xtreme Performance Street Sprung Clutch Kit for Mitsubishi models (inc. Eclipse Turbo)

The ACT ACT Xtreme Performance Street Sprung Clutch Kit for Mitsubishi models including the Eclipse Turbo and compatible applications replaces the factory clutch with an ACT system engineered to handle more torque and heat. The ACT Xtreme pressure plate provides maximum Xtreme clamp load, highest single-disc hold available, and the performance street sprung disc delivers smooth, daily-driver engagement with more strength than OEM.

DETAILS

• Pressure plate: ACT Xtreme
• Clutch disc: Performance Street Sprung
• Clamp load: maximum Xtreme clamp load, highest single-disc hold available
• Engagement: smooth, daily-driver engagement with more strength than OEM
• Use case: street-modified builds, daily-driven performance cars

ACT pressure plates use precision cover stampings and four-stage heat-treated diaphragms. The ACT Xtreme pressure plate’s diaphragm geometry is calibrated to deliver maximum Xtreme clamp load, highest single-disc hold available without unnecessary pedal weight increase. Chrome-moly hubs on all ACT discs are heat-treated for strength and long-term durability under repeated heat cycling.

This kit is application-specific to Mitsubishi models including the Eclipse Turbo and compatible applications. ACT engineers each clutch kit for the correct disc diameter, pressure plate sizing, and disc specification for the application. Installing a correctly specced ACT kit means the geometry and spring rates are correct, not adapted from a universal or shared-platform design.

Why Choose ACT

Advanced Clutch Technology has been manufacturing performance clutch systems in the United States since 1993. Every ACT pressure plate uses a proprietary diaphragm design that increases clamp load and reduces deflection compared to OEM units, and every diaphragm goes through a four-stage heat-treating process before it leaves the factory. The result is a clutch system that holds more power than the stock unit, engages more precisely, and lasts longer under the kind of driving that wears factory clutches out quickly. ACT designs each application from scratch rather than modifying OEM tooling, which means the fitment is precise and the performance is intentional. Whether the build is a street-driven daily driver or a dedicated track car, ACT offers a kit at the correct specification for the use.

The RallySport Take

The ACT Xtreme Performance Street Sprung is the correct clutch for high-power modified builds that still operate as street cars. The Xtreme pressure plate delivers maximum clamp load from a diaphragm-style pressure plate — more holding power than the Heavy Duty plate, at a pedal weight that is manageable for daily use. Paired with the Performance Street organic disc, engagement remains smooth and progressive. The street disc’s organic friction material transfers heat well, the steel-backed lining handles burst loads above what the OEM disc was rated for, and reduced marcel means faster engagement response. If the HD clutch is slipping and the Xtreme is required, this is the kit. Fits Mitsubishi applications 1990-1999.
