Show original supplier description
The South Bend Clutch SDD3250-5K Organic/Ceramic Street Dual Disc Clutch Kit is a performance upgrade for 1994-2004 Dodge RAM 2500/3500/4500 trucks equipped with the 5.9L Cummins engine and an NV4500 5-speed manual transmission. This Stage 4 dual disc clutch is engineered to handle significant power and torque, rated for up to 650 horsepower and 1300 ft-lbs. The kit utilizes a unique multi-friction disc design. The outer portions of the discs are made with organic material for smooth engagement and comfortable daily driving, while the inner portions feature ceramic buttons for enhanced grip and superior heat resistance during demanding use. This dual-friction approach ensures driveability without compromising performance. Key features of this South Bend Clutch kit include a 3250 lb. diaphragm-style pressure plate for substantial clamping force, a dampened center plate to minimize gear rollover noise, and a free-travel disc design common in semi-trucks to prevent transmission wear. It also comes with a billet flywheel and an upgraded 1-3/8 inch input shaft, addressing the OE shaft's tendency to twist under high torque. This clutch is ideal for applications involving heavy towing, with a capacity of up to 30,000 lbs, and offers smooth engagement coupled with high holding power for performance-oriented trucks. The kit provides everything needed for a complete installation, offering a robust solution for driveline upgrades.
