Quick Ship SKU #: NMU70279-04-5SCE VALAIR NV4500 13" x 1.25" Performance Clutch 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 600 horsepower due to its ceramic facings.

MORE INFORMATION:

• Ceramic/Ceramic: These clutches utilize two ceramic facings on the clutch disc and are aimed at the high performance trucks, these are the best of bad clutches. Driving manners are very performance oriented with no clutch slip, basically the clutch is in, or it is out. Great holding capacity for highly modified trucks, the only way you will get more holding power is to go to a Double Disc Clutch setup. Ceramic is a very hard material so typically flywheel wear is more noticeable using a ceramic clutch than with other materials. Pedal pressure is typically a little higher than factory pedal pressure depending on plate pressure(3200#, 3400#, 3800#). Drive train and Hydraulic upgrades are recommended. Some clutch rattle may be noticed while idling in neutral. Ideally suited to trucks with high performance power modifications with 550-650HP. (Not recommended for towing)
