Reliable Power Handling for Your 2006 LBZ Duramax

The South Bend Clutch SDM0506CBK Dyna Max Performance Clutch Kit is the ideal upgrade for 2006 LBZ Duramax owners who want more holding power without sacrificing drivability. Rated for 450 horsepower and 900 lb-ft of torque, this complete single-disc clutch kit converts the factory dual-mass flywheel to a durable solid flywheel while delivering strong, consistent engagement under load.

Whether you're tuned for more power, towing heavy, or simply want to eliminate the common failures of the stock clutch and dual-mass flywheel, the SDM0506CBK gives you a robust, serviceable solution designed specifically for the LBZ platform and ZF6 6-speed manual transmission.

Key Features & Benefits
