South Bend 1939DF Clutch Kit

Enhance your Ford 7.3L Powerstroke driving experience with the South Bend 1939DF Clutch Kit. Tailored for both daily driving and high-performance needs, this kit is perfect for vehicles with modified engines that require a clutch capable of handling increased torque while ensuring smooth engagement. Offering Kevlar/ceramic friction materials, this kit is designed for durability, superior performance, and enhanced drivability.

Kevlar/Ceramic Multi-Friction Material: The Kevlar/ceramic combo clutch material combines the heat resistance and durability of ceramic with the smooth engagement and longevity of Kevlar. This dual-sided design features Kevlar fibers on one side for consistent, low-dust engagement and ceramic material on the other for increased friction and heat management. This blend makes it a versatile choice for vehicles requiring both drivability and enhanced performance. Ideal for light performance use, daily driving with occasional towing, and off-road adventures, the Kevlar/ceramic clutch offers improved torque capacity without compromising pedal feel. The ceramic side ensures superior heat dissipation under load, while the Kevlar side extends clutch life by reducing wear and clutch fade. This combo is perfect for drivers wanting a performance upgrade while maintaining comfort for regular use. 

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. 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.

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 2 Clutch: A Stage 2 clutch offers a significant performance boost compared to Stage 1 setups. Designed with stronger friction materials like Kevlar or ceramic, it provides higher torque capacity and heat resistance. This stage is ideal for moderately modified vehicles, including turbocharged setups, nitrous systems, and track-ready builds needing enhanced grip and reduced slippage. Although it offers increased power handling, Stage 2 clutches can introduce a slightly stiffer pedal feel and more aggressive engagement than Stage 1, making them better suited for drivers prioritizing performance while still requiring reasonable street drivability.
