VALAIR NV4500 13" x 1.25" Performance Clutch Kevlar/Ceramic HD Spring Hub 94-02 Dodge 5.9L Cummins

One of the easiest ways to get increased holding power from a clutch is to increase the surface area, right? Well, the factory NV4500 featured a 12-1/4" diameter facing, where the later 6 speed NV5600 jumped to a 13" so wouldn't it make sense to upgrade to a 13"? Sure it does! Valair offers this upgraded clutch kit specifically for 5 speed NV4500's that converts it to a 13" clutch disc and features a heavy duty spring hub that can handle up to 500 horsepower due to its Kevlar and ceramic facings.

MORE INFORMATION:

• Utilizing two different buttons on the clutch disc these clutches are aimed at the moderate performance trucks. Driving manners are very good for everyday driving and towing. Take-offs are 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. Pedal pressure is typically a little higher than factory pedal pressure. Drive train upgrades are not usually required. Some clutch rattle may be noticed while idling in neutral due to the HD Hub Design.
• Ideally suited to trucks with moderate performance power modifications with 350-500HP.
