Dual Disc Street Clutch Upgrade for Early-Model 6.6L Duramax

If your Duramax is putting down more power than stock and your factory clutch is starting to wave the white flag, the South Bend Organic Street Dual Disc Clutch is the upgrade that bridges everyday driveability with serious holding power. Designed specifically for 2001–2005 GM 2500HD and 3500HD trucks, this clutch kit is a perfect match for owners who tow, daily drive, and run mild to moderate performance tuning. At the heart of this kit is a dual disc setup featuring organic friction material, which gives you a much smoother engagement than ceramic while still offering the increased surface area and torque capacity you need. It’s designed to handle performance gains without making stop-and-go traffic a chore, so if your truck sees as much pavement as it does payloads, this setup gives you that extra bite without sacrificing comfort.

Heavy-Duty Construction & Design

The sprung hub helps dampen drivetrain shock and reduce chatter, and the 12" disc diameter adds surface contact for consistent grip under load. South Bend includes a diaphragm-style pressure plate to keep pedal feel manageable, along with a hydraulic throwout bearing and alignment tool to simplify installation. Every component is built with quality and longevity in mind—right down to the 10-spline input and 1.375" shaft compatibility that ensure it fits right into your transmission. Whether you’re hauling heavy, running a tune, or just want to upgrade before your stock clutch calls it quits, this kit offers real-world strength with a factory-like pedal feel. It’s the kind of clutch you can drive every day—but still trust when it’s time to put that Duramax torque to work.
