Description
Owners of 1989–1998 Nissan 240SX looking to refresh or upgrade the clutch system can use the EXEDY Performance Clutch Kit – 1989–1998 Nissan 240SX as a fitment-focused option developed around enthusiast street, autocross, HPDE, and modified performance builds.
Manufacturer Background
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.
Why This Part Fits the Build
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.
Available Configurations
This parent listing contains multiple EXEDY configurations for the same application family. The differences below are functional and should be selected around torque demand, heat load, and acceptable engagement behavior.
| Configuration | EXEDY Part Number | Construction / Character | Torque Capacity | Recommended Use |
|---|---|---|---|---|
| Hyper Single | NH08SD | Single-plate Hyper clutch with dedicated lightweight flywheel; sprung-center disc, push-type cover. Performance-oriented but more manageable than multi-plate systems. | Application-specific | Moderately to highly modified street/track cars that do not require a twin |
| Hyper Twin | NM092SD | Twin-plate Hyper system with lightweight chromoly flywheel; sprung-center disc, push-type cover. Direct, motorsport-oriented engagement. | EXEDY general Hyper Twin family rating: approximately 500 ft-lb at the flywheel; verify the exact SKU/application | High-power street, drag, road-race and rally applications |
Which Option Makes Sense?
For 1989–1998 Nissan 240SX, the Hyper Single is the more sensible choice when the car still sees meaningful street mileage and the power level does not justify two friction discs. The Hyper Twin is intended for a materially higher torque/heat load and is better suited to serious forced-induction, drag, or repeated road-course use.
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: 1989–1998 Nissan 240SX
- EXEDY SKUs: NH08SD, NM092SD
Application-specific construction notes: Sprung-center disc, Push-type cover, Cerametallic friction.
Fitment note: Because clutch fitment is sensitive to transmission and flywheel changes, verify the complete vehicle configuration before purchase. Modified swaps or previously converted flywheel systems may require a different EXEDY part than a stock vehicle.
