South Bend Clutch (SBC) aims to deliver exceptional quality, performance, and reliability through our meticulously designed clutch kits. Our SBC SD1-2221R-12 Clutch Kit exemplifies our commitment to innovation and excellence in the automotive industry. This product lineup caters to a wide range of applications, from daily driving to high-performance racing, ensuring compatibility with various driving demands and preferences. Our clutch kits are designed with precision engineering to enhance your vehicle's drivability and performance.

Our clutch kits are available in multiple variants to suit different driving styles and requirements. The options include Organic, Ceramic, and Kevlar friction materials, which are selected to optimize performance, durability, and heat resistance. Each material offers unique benefits:

Organic friction material provides smooth engagement and is suitable for daily driving and light performance applications. It offers a balance between performance and longevity, making it an ideal choice for drivers who seek enhanced drivability without sacrificing the comfort of the ride.
Ceramic friction material is designed for extreme conditions, offering higher heat resistance and durability. It is ideal for high-performance and racing applications, where higher horsepower and torque levels require a clutch that can handle intense operating conditions without fading or slipping.
Kevlar friction material offers a great compromise between the smooth engagement of organic material and the durability of ceramic. It provides excellent wear resistance and heat tolerance, making it suitable for sport driving and moderate performance applications.

Our clutch kits are engineered to meet the specific needs of gas engines, with an 18 input spline and a 1.19-inch input shaft diameter, ensuring a perfect fit and optimal performance for your vehicle. The disc diameter is standardized at 11 inches across the variants, providing a broad surface area for efficient power transmission.

The SBC SD1-2221R-12 Clutch Kit variants are designed with different stages and usage levels in mind:

Stage 1 variants are tailored for daily driving with an added performance edge, suitable for vehicles that are driven regularly but may have minor performance upgrades.
Stage 2 variants cater to more aggressive driving and moderate performance applications, including sport driving and occasional track use. These are designed for vehicles with more significant performance upgrades, requiring a clutch that can handle increased power while maintaining smooth operation.

Each kit includes a single clutch disc, designed with specific styles to match the friction material and intended use. The full face disc style is common across our organic and Kevlar variants, providing a large contact area for smooth engagement and consistent performance. The ceramic variant features a 6-paddle disc style, which offers a more aggressive engagement ideal for extreme applications. All our clutch discs feature a sprung hub style which helps in reducing drivetrain shock during engagement, thereby extending the lifespan of the clutch system and improving ride quality.

The pressure plate style utilized in our clutch kits is the Lever Type, which is designed for reliability and optimal clamping force, ensuring that the power from your engine is efficiently transferred to the drivetrain without slippage. Our clutch kits are designed for ease of installation and include all necessary components to ensure a complete and straightforward setup. Each kit comes with a throw-out bearing, an alignment tool, and a pilot bushing made from durable bronze material, providing you with everything needed for a successful installation.

While our clutch kits do not include a flywheel, they are compatible with a wide range of OEM and aftermarket flywheels, allowing you to choose the best option for your vehicle and driving needs. This flexibility ensures that you can tailor your drivetrain setup to achieve the perfect balance of performance, drivability, and durability.
