South Bend Clutch DDDCMAX-Y Competition Triple Disc Clutch Kit Sintered Iron 950HP 1500 ft-lbs

The South Bend Clutch DDDCMAX-Y is a heavy-duty Competition Triple Disc Clutch Kit engineered for high-output diesel trucks running a ZF S6-650 6-speed manual transmission. Rated to handle up to 950 HP and 1,500 lb-ft of torque, this Stage 4 kit is purpose-built for extreme performance applications including drag racing, sled pulling, and high-horsepower street builds where stock or standard aftermarket clutches fall short.

The triple-disc architecture dramatically increases friction surface area, allowing the system to manage heat more effectively and maintain clamping force under the sustained high-energy engagements that competition use demands. Modified to handle higher plate loads, these Competition Triple-D kits wear better, maintain compression longer, and resist warping significantly better than standard alternatives. GM applications utilize feramic buttons for superior holding power — feramic material delivers exceptional thermal resilience while remaining slippable, making it ideal for sled pulling and racing scenarios.
