Valair Performance Diesel NMU70NV56DDSN Clutch Kit – 2001–2005 5.9L Cummins (NV5600)

The Valair Performance Diesel NMU70NV56DDSN is a dual disc clutch kit designed as a high-performance upgrade for 5.9L Cummins-powered trucks equipped with the NV5600 transmission. Built to handle increased horsepower and torque, this setup provides strong holding capacity while maintaining improved drivability compared to a single disc clutch.
