This ceramic clutch utilizes ceramic buttons on both sides of the clutch disc and is aimed more for the performance trucks. The driving manners are very performance oriented with no clutch slip, basically the clutch is in, or it is out. Great holding capacity for modified trucks, the only way you will get more holding power is to go to a Dual Disc Clutch setup. Ceramic is a very hard material so typically flywheel wear is more noticeable using a ceramic clutch than with other materials. This clutch has a small window of usage, ideally suited to trucks with performance power modifications that do not intend to tow with there truck. (Towing with a clutch such as this could be difficult and frustrating)
If you’re looking to tow with the truck, but you need something to hold 550HP then you’d want an Organic Street Dual Disc. This clutch is ideal for trucks from stock to 550HP that tow heavy on a regular basis. Clutch engagement will be very close to stock feel.
The VALAIR 13" UPGRADE CLUTCH NMU70279-04-5SCE is designed to work with the factory sized input shaft on the NV4500 transmission.
