Product Description

The ACT AI4-HDSS Heavy Duty Street Sprung Clutch Kit is a high-performance single-disc clutch assembly designed for street-driven vehicles that may see enthusiastic driving or mild race use. Featuring ACT's Heavy Duty pressure plate, this kit increases clamp load over stock to improve torque handling and durability, while the performance street sprung disc uses premium organic friction material with a sprayed hub to cushion driveline shock and noise - ideal for daily drivers that want a stronger clutch without overly harsh engagement.

This complete kit includes a Heavy Duty pressure plate, performance-oriented clutch disc, pilot and release bearings, and an alignment tool for easier installation. The organic sprung disc delivers smoother engagement and longer service life compared to stock while improving overall performance under load. It's a direct-fit replacement for many Honda and Acura models like the 1994-2001 Integra, 1999-2000 Civic Si, 1994-1997 Civic del Sol, and 1998-2001 CR-V - though a matching flywheel (sold separately) is required for full clutch assembly.
