Our clutch kits are available in several configurations to suit different driving styles and performance requirements. Whether you're upgrading your car for better daily driving responsiveness, seeking more grip for racing applications, or need a robust system for towing and heavy-duty use, South Bend Clutch offers a solution tailored to your needs. The variants of the SBC SD1-2439R-12 Clutch Kit include options for organic, ceramic, and Kevlar friction materials, each selected to optimize performance and longevity for its intended use.
The organic variant is ideal for drivers looking for a significant improvement over their factory clutch without sacrificing drivability. It offers smooth engagement, making it perfect for daily driving with a plus of performance. The ceramic option, on the other hand, is designed for those who demand extreme performance. It provides aggressive engagement with higher heat tolerance, making it suitable for racing or high-performance applications. Lastly, the Kevlar variant is engineered for those who need a balance between performance and durability. It offers superior wear resistance and is perfect for sport driving or vehicles used in high-demand situations.
Each clutch kit variant is designed with specific stages in mind - Stage 1 for daily driving improvement and Stage 2 for more demanding conditions, ensuring that there's a perfect match for your vehicle and driving habits.
South Bend Clutch kits are not just about the friction material. Each component of the clutch has been thoughtfully designed and manufactured to ensure optimal performance and durability. The pressure plate, disc style, and hub design are all selected based on the unique demands of each kit's intended use. For example, our Stage 1 kits typically feature a diaphragm-style pressure plate for reliable, consistent engagement and a full-face disc for smooth operation. Our Stage 2 kits might employ the same reliable pressure plate design but paired with a full-face disc made from more durable materials like Kevlar to handle more rigorous use.
Every South Bend Clutch kit comes complete with all necessary components for installation, including a throw-out bearing and an alignment tool. We understand that a clutch upgrade can be a significant investment, and we aim to make the installation process as straightforward as possible. While our clutch kits do not include a flywheel, they are compatible with OEM and most aftermarket flywheels, allowing you to tailor your setup to your specific needs and preferences.
Choosing the right clutch kit is crucial for achieving the performance and reliability you expect from your vehicle. South Bend Clutch's extensive experience and commitment to quality have made us a preferred choice among drivers and technicians alike.

Choose South Bend Clutch for your next clutch upgrade and experience the difference that quality, performance, and reliability can make in your driving experience.
Organic Friction Material
Organic clutch material is a top choice for drivers seeking smooth, reliable performance for everyday use. Made from a blend of woven organic fibers and resin compounds, it offers excellent friction stability, making it ideal for street driving where comfort and longevity are priorities. Its consistent engagement and reduced noise make it particularly suited for daily drivers, light towing, and moderate performance applications where clutch feel matters.
Designed to handle moderate torque loads, organic clutch discs excel in standard driving conditions but may wear faster under extreme stress compared to performance-based materials. However, they remain a cost-effective and dependable option for drivers who prioritize comfort and balanced performance over extreme power handling.

Sprung Hub Style
The sprung hub clutch is a versatile design focused on balancing performance with drivability. It features a series of dampening springs integrated into the hub, which help absorb vibrations and reduce shock during clutch engagement. This design is ideal for daily drivers, street performance vehicles, and light towing, where smooth gear changes and reduced drivetrain stress are essential.
By minimizing shock transfer, the sprung hub clutch prolongs the life of other drivetrain components, making it a reliable option for vehicles needing both comfort and moderate power handling. While slightly less direct in power transfer than a solid hub, it offers a superior driving experience for most street and light performance applications.

Full Face Disc Style
The full face clutch disc is designed for smooth engagement, even wear, and maximum surface contact with the pressure plate and flywheel. Covering the entire friction surface, this design provides excellent power transfer, making it ideal for daily drivers, light towing, and vehicles where comfort and longevity are top priorities. The increased surface area allows for better heat distribution, reducing the risk of premature wear.
Full face discs excel in standard and moderate performance applications, offering a balanced blend of drivability and durability. However, they may lack the aggressive grip required for extreme power handling compared to paddle-style discs, making them better suited for stock to lightly modified vehicles.

Single Disc
A single disc clutch is the most common and straightforward clutch design, featuring one friction disc to transfer power from the engine to the transmission. Known for its simplicity and reliability, it is ideal for standard vehicles, daily drivers, and light performance applications. Single disc clutches provide smooth engagement, making them perfect for casual driving and moderate power outputs.
While single disc clutches offer excellent drivability and cost-effectiveness, they have limited torque capacity compared to multi-disc setups. This design is best suited for vehicles with moderate horsepower levels where comfort, longevity, and ease of use are the primary concerns.

Stage 1 Clutch
A Stage 1 clutch is designed for drivers seeking a slight performance upgrade over a stock clutch while maintaining smooth engagement and drivability. Ideal for daily drivers and mild performance enhancements, it offers increased clamping force and better heat resistance compared to factory clutches. This makes it suitable for vehicles with minor bolt-on modifications, such as intake or exhaust upgrades.
While Stage 1 clutches provide improved durability and power handling, they maintain a comfortable pedal feel and minimal noise, making them a perfect choice for street driving with light towing or occasional spirited driving. They balance performance with everyday usability.
