The HC5-HDSS kit pairs ACT's most popular Heavy Duty pressure plate with its most popular Performance Street disc for the 1992-2005 Civic/Civic del Sol/Acura EL platform. The Heavy Duty pressure plate uses ACT's exclusive diaphragm design, four-stage heat treating, and precision cover stampings to increase clamp load and reduce deflection. The Performance Street disc uses premium organic friction material with high copper content for better heat transfer and a steel backing for greater burst strength and durability, with reduced marcel for faster, more direct shift action.

Frequently Asked Questions
Are ACT clutch kits balanced?
Yes. Every ACT clutch assembly is computer spin-balanced to within .25 oz-in, tighter than the .50 oz-in typical of stock production clutches, for smoother operation across the RPM range.
Will this clutch increase pedal effort?
ACT pressure plates are engineered for higher torque capacity, so pedal effort typically increases 15-40% with a Heavy Duty pressure plate and 50-80% with an Xtreme pressure plate compared to stock, depending on the application.
Does this clutch need a break-in period?
Organic street discs should be broken in for 300-500 miles of mild, stop-and-go driving before spirited use. Race discs generally only need a few hard slips to lap the surfaces before normal use. Avoid overheating the clutch during break-in, as this can glaze the friction surfaces.
Is this clutch kit repairable or rebuildable?
In some cases a rebuild or repair may be possible after inspection; contact ACT's technical department for guidance, and use a qualified clutch specialist due to the kit's specialized components.
