Description
Owners of 2005–2010 Chevrolet Cobalt / 2006–2008 Chevrolet HHR / 2007–2009 Pontiac G5 looking to refresh or upgrade the clutch system can use the EXEDY Performance Clutch Kit – 2005–2010 Chevrolet Cobalt / 2006–2008 Chevrolet HHR / 2007–2009 Pontiac G5 as a fitment-focused option developed around daily-driven and enthusiast street applications that need dependable engagement and OE-correct fitment.
EXEDY Engineering Background
EXEDY's history reaches back to 1923 in Japan, with decades of clutch development under the Daikin Clutch name. The company is both a major OEM powertrain supplier and a long-established performance-clutch manufacturer, with products engineered for everything from original-power street cars to dedicated motorsports use.
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 |
|---|---|---|---|---|
| Stage 1 Organic | 04801 | Ultra-Fiber organic, sprung center. Smoothest performance option; typically closest to stock. | Application-specific; higher than OE | Street, canyon, autocross and light track use on mildly modified engines |
| Stage 2 Cerametallic – Thick Disc | 04950 | Thick cerametallic disc. Aggressive, with added thermal mass. | Application-specific | Hard street/track use where repeated heat cycles and torque capacity take priority |
How to Choose
For 2005–2010 Chevrolet Cobalt / 2006–2008 Chevrolet HHR / 2007–2009 Pontiac G5, start with Stage 1 when street manners and modulation are the priority; step to Stage 2 when torque output, repeated heat, launches, or track use demand more bite. Where thick, thin, or cushion-button Stage 2 discs are offered, choose thick for broader thermal durability, thin for lower rotating inertia/quick shifts, and cushion-button for a more progressive compromise.
Core 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: 2005–2010 Chevrolet Cobalt / 2006–2008 Chevrolet HHR / 2007–2009 Pontiac G5
- EXEDY SKUs: 04801, 04950
Application-specific construction notes: Cerametallic friction.
Fitment note: Fitment should be verified against the exact drivetrain, not model name alone. Check year, engine, transmission, and any existing flywheel or EXEDY clutch-system part number before installation.
