  • If you're running a B-series Integra for drag, drift, road racing, or a high-horsepower street/strip build, the Action Clutch Stage 4 (1MD) Metallic Rigid Kit (ACR-0477) is built for exactly that. This is not a daily driver clutch - Stage 4 means aggressive engagement, a firm pedal, and clutch chatter during low-speed operation. That's the trade-off for serious holding power, and if you're at this stage, you already know what that means.

    At the core of this kit is a heavy-duty single diaphragm pressure plate with reinforced drive straps, designed to clamp harder and hold more power than the stock unit. Paired with it is an Unsprung MIBA Ceramic disc available in 4-puck or 6-puck configuration. The unsprung (rigid) design eliminates the torsional dampening springs found on street clutches, which is what delivers that snappy, direct power transfer you need under hard acceleration. Expect some chatter at low RPM during the break-in period - this is normal and minimizes once the disc is properly seated.

    What Stage 4 means for your build: Action Clutch rates this kit at 170% increased holding capacity over the factory clutch. It's engineered for race applications including drag racing, road racing, and drift - and it performs well on high-horsepower naturally aspirated and boosted B-series builds. If you're making serious power and the stock clutch is slipping, this is a proven upgrade path.

    Fitment: This kit fits 1994-2001 Acura Integra with the 1.8L DOHC B-series engine. Compatible engine codes include B18B1 (Non-VTEC), B18C1 (VTEC - GS-R), and B18C5 (VTEC - Type R). Compatible trim levels: RS, LS, GS, GS-R, and Type R. Both cable and hydraulic clutch configurations within the supported year range are covered - verify your specific submodel before ordering.

    Engineering and quality control: Every Action Clutch kit is inspected and signed off by an in-house engineer before it ships. The team carries over 60 years of collective clutch engineering experience, and each finished kit is checked for clamping force consistency, disc balance, and component fitment before it leaves the facility.

    Part number cross-reference: Manufacturer SKU ACR-0477 (also listed as ACC-CLK-01-16). Use ACR-0477 when searching compatibility databases or verifying fitment with your shop.

  • Fits: 1994-2001 Acura Integra - All Trim Levels (RS, LS, GS, GS-R, Type R)

    Compatible Engines:

    • 1.8L DOHC B18B1 - Non-VTEC (1994-2001 RS, LS, GS)
    • 1.8L DOHC B18C1 - VTEC (1994-2001 GS-R)
    • 1.8L DOHC B18C5 - VTEC (1997-2001 Type R)

    Note: Verify your clutch actuation type (cable vs. hydraulic) and flywheel specification before installation. This kit is not designed for stock daily-driven vehicles - see Stage 1 or Stage 2 kits for street applications.

  • Break-In Procedure (Required): 500 street miles minimum. During break-in: keep RPM under 4,500, use no more than half throttle, and do not apply boost if your vehicle is turbocharged or supercharged. Proper break-in is required to retain warranty coverage, ensure full holding capacity, and allow the ceramic disc to seat correctly against the flywheel and pressure plate surface.

    Clutch Chatter: Some chatter at low RPM and during slow-speed engagement is expected with an unsprung (rigid) ceramic disc. This is a normal characteristic of the Stage 4 design and minimizes after the break-in period is complete. It is not a defect.

    HP and Torque Capacity: Rated for race and high-horsepower B-series builds. Consult Action Clutch or your installer if your build exceeds 400whp to confirm disc puck count selection (4-puck vs. 6-puck) is appropriate for your application.

  • What's Included - Action Clutch Stage 4 Kit (ACR-0477):

    • (1) Unsprung MIBA Ceramic Clutch Disc - 6 Puck (4-puck disc available as alternate configuration)
    • (1) Single Diaphragm Heavy-Duty Pressure Plate
