Add the Valair Heavy Duty Upgrade Clutch NMU70241-06 to your 1999-2003 Ford 7.3L Powerstroke 6-Speed and utilize two different buttons on the clutch disc. The Valair Heavy Duty Upgrade Clutch is aimed at the moderate performance trucks. Driving manners are very good for everyday driving and towing. Take-off is relatively smooth and offer more slip and forgiveness than the ceramic/ceramic clutches. While the holding power for the Kevlar faced clutch is higher than the organic/organic faced clutches, the main advantage is less wear on the flywheel and longer life. Ideally suited to trucks with moderate performance power modifications. If towing more than the occasional 7,500-10,000lbs the Organic Dual Disc will be a better option. Features: 13" x 1.375" Stock Organic Replacement Ceramic / Kevlar Buttons (both sides of disc shown) HD Spring Hub Rated @ 500HP / 1000 ft lbs Torque 3400# Pressure Plate Kit Includes: 3400# Pressure Plate, Heavy Duty Clutch Disc, Release Bearing, Pilot Bearing and Alignment Tool.
