Exedy Racing Clutch Hyper Single Clutch for Acura NSX 1991-2005, 375 Torque Capacity - HH04SD1

Introducing the Exedy HH04SD1 Hyper Single Clutch, a solid choice for those looking to enhance their Acura NSX's performance without going overboard. Designed specifically for the NSX model years 1991 to 2005, this clutch strikes a balance between power and drivability, making it ideal for moderately modified vehicles. Customers have noted that the installation process is straightforward, and many have experienced a noticeable improvement in their car's responsiveness.

The HH04SD1 features a robust purple anodized, forged aluminum cover that not only looks great but also offers superior stiffness compared to standard stamped covers. This means you can enjoy a higher lever ratio while maintaining a comfortable pedal feel. Users have commented on how the clutch feels more engaging without being overly stiff, which is a common concern with performance upgrades.

One of the standout features of this clutch is its innovative pressure plate design, which incorporates turbine-like vanes. These vanes enhance airflow, helping to keep the clutch cooler during intense driving conditions. As a result, many customers have reported less wear and tear over time, leading to a longer lifespan for the clutch.

The Exedy HH04SD1 comes equipped with a lightweight chromoly steel flywheel, which is a significant upgrade from the OEM option. This flywheel not only improves engine response but also contributes to a lighter overall assembly, making for quicker shifts and less strain on your transmission's synchros. Customers often mention how much easier it is to shift gears with this setup, appreciating the reduction in inertia.

Here are some key specifications of the HH04SD1:

  • Disc Type: Cera Metallic Single Disc Sprung Center Disc
  • Spline: 24 Spline
  • Torque Capacity: 375 torque capacity at the wheels

Fitment:

  • Acura NSX Base 3.0 (1991-2005)

Notes:

  • Flywheel crank bolts required: Part # 90011-PR7-000 (8 pcs)
  • Input shaft must be changed on transmission for 91-96 models

Overall, the Exedy HH04SD1 Hyper Single Clutch offers a blend of performance and practicality, making it a popular choice among NSX enthusiasts. Whether you're hitting the track or enjoying a spirited drive on the road, this clutch is designed to elevate your driving experience.
