Description
Designed around the drivetrain package used in 1991–2005 Acura NSX, the EXEDY Hyper Single Clutch Kit – 1991–2005 Acura NSX is intended for drivers prioritizing enthusiast street, autocross, HPDE, and modified performance builds and correct EXEDY component matching.
A Century of Clutch Engineering
EXEDY combines more than a century of Japanese clutch-manufacturing experience with a substantial OEM and motorsports presence. Originating in 1923 and known historically through Daikin Clutch, EXEDY designs replacement, sport, and racing driveline products with an emphasis on repeatable clamp load, heat management, durability, and controlled engagement.
Product Overview
EXEDY's performance single- and multi-plate systems are intended to raise torque capacity and heat tolerance while matching the engagement characteristics to the car's intended use. Stage 1 uses an organic friction strategy for the most street-friendly behavior; Stage 2 moves to cerametallic friction for harder use; Hyper systems add dedicated flywheel and multi-plate architecture for substantially higher-output builds.
Choose the least aggressive configuration that comfortably covers the engine's torque and heat load. That approach normally gives the best balance of drivability, service life, transmission friendliness, and track durability.
Configuration
- EXEDY Part Number: HH04SD1
- Configuration: Hyper Single Clutch Kit
- Construction / Character: Application-specific EXEDY configuration; sprung-center disc, pull-type cover
- Torque Rating: Application-specific / verify EXEDY rating
- Best Suited For: Use where this exact EXEDY configuration and fitment are required
How to Choose
For 1991–2005 Acura NSX, this configuration makes the most sense when its intended duty matches the vehicle's actual power and use. Avoid overspecifying clutch aggressiveness: the best setup is the one that maintains the needed torque reserve while preserving usable modulation and protecting the rest of the driveline.
Key Technical Specifications
- Clamp Load: Stage 1/2 covers are designed around roughly 40% higher clamping load than the genuine part
- Pedal Effort: Typical Stage 1/2 increase is approximately 20–35%, application dependent
- Flywheel Compatibility: Stage 1/2 generally use the OEM flywheel unless noted; Hyper systems include/require their dedicated flywheel
- Certification: EXEDY Stage 1, Stage 2 and Lightweight Flywheel products are SFI 1.1 certified
- Vehicle Application: 1991–2005 Acura NSX
- EXEDY SKU: HH04SD1
Application-specific construction notes: Sprung-center disc, Pull-type cover.
Fitment note: Before ordering, confirm the exact year, trim, engine, transmission, and flywheel/clutch-system combination. EXEDY may use different components within the same model range, particularly where transmissions or factory flywheel designs changed.
