VALAIR NV4500 13" x 1.25" Performance Clutch Ceramic HD Spring Hub 94-02 Dodge 5.9L Cummins
Description
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)
About Valair Clutch
SHOP VALAIR CLUTCHES AND CLUTCH PARTS AT DPP!
When we at Diesel Power Products started shopping around for a diesel clutch manufacturer to showcase, we had a lot of choices. It soon became clear that one company offered the combination of quality, durability, customer service, price and integrity that we were looking for. Valair Clutch has not failed to live up to our expectations.
Valair started as Vallance Remanufacturing in Mineral Wells, Texas, about 60 miles West of Fort Worth, in the early 1990s. The company concentrated on rebuilding clutch assemblies for heavy trucks and agriculture. The location allowed Valair to keep cost low and supply the Dallas/Fort Worth area as well as the local areas with quality replacement parts.
In 2004, Valair addressed an interest in the performance clutch market for high horsepower diesel trucks. Research and development started to source the parts for these applications. Valair was already building clutches for most OTR trucks capable of holding up to 2250 ft. lbs torque and was adapting these principles from these OTR clutches into a smaller package for ¾ and 1 ton trucks.
After two years of R&D, Valair's ˜Performance Series Clutches were marketed to the diesel truck enthusiast who wanted a quality high performance clutch at a reasonable price. All of these clutches are assembled in Mineral Wells, Texas from the highest quality parts available and are now being sold all over the World.
Whether you are looking for a stock replacement, towing clutch, or a high performance clutch for sled pulling or drag racing, they have just the clutch for you.
