Bought a Hays supertruck clutch for nv 2500 in my 2003 dodge, upon removal of what I know to be the stock clutch I made a surprising discovery. The clutch discs and pressure plate looked identical and even had matching numbers stamped into them. The Hays clutch had been sold to a friend of mine for his '02. If you have a serious truck with some hp upgrades I wouldnt waste time with the Hays. It almost appears that they are selling stock 3rd gen truck clutches as an upgrade for the 2nd gen since the newer models had a higher clampload anyway. Just an opinion based on my observatioins. Thought Id let everyone know.
