Exedy told me that the Exedy Twin was NOT designed for normal driving (right after the single failed and they sold me the Dual AND said that is what I should have used) and told me that the dual is for strip use only and that is why it failed so they gave me a single for warranty, which I sold

I started to look at the Tex dual plate and with help from one of their head guys there, I started checking the "stack up measurements" WHICH MEANS
When you have a hydraulic release brg inside a bellhousing after you install all you internal parts of the clutch system there needs to be a .060 gap between the release bearing and the fingers of the pressure plate (with no fluid in system and pushing the release brg back) if not you will prematurely wear out the discs. All this can change when you install aftermarket flywheels, release brgs, pressure plates AND differant stroker cranks and versions of the LSX blocks. On the Exedy Dual with my LS2 stroker build up I ended up with the release bearing pushing IN on the fingers about .110.
That is why the first and second Exedy clutches wore out. They came with a flywheel, I don't know if that was the only problem because it had a aftermarket stroker crank and I used a LS2 block instead of a LS6 block in my 2002 ZO6. With the Tex Dual I ended up machining about .080 OFF the pressure posts which pulled the fingers in about .125 to give me the .060 gap I needed. This was all done with the help over the phone from the main brain at Tex clutches. On the triple plate clutches they machine the release brg housing so they get that clearance. Alot of people aren't even checking this measurement and after I learned about it, I have seen alot of issues.

Thanks for the explanation. I will be using the single disc setup Exedy, and a stock LS6 block. I was going to buy a Tex, and was ordering from LGM, and they talked me into getting the Ex. It cost alot more, but they insisted it was a better clutch for my application. Since then, the Centerforce has been used more, and is much cheaper than either Tex, or Ex, so I'd probably go with it now. I hope I don't have your premature wear problem with the Ex, since it cost so friggin' much.
