    I believe mine was Hayes(sp?) and it was a "diaphram" type, which is many small fingers, instead of the 3 large ones. Not sure if it is that or the hydraulic clutch that makes engagement so smooth, but I would definitely go that route. I have no problems with it slipping, even in low and trying to crawl over stuff with lots of throttle.

    And I'd want to make sure I had a 12" or 11.5" or whatever they called them, not the 10".

    Guy I knew had a centerforce put in his early mustang, and it would spin the tires going into 2nd, which it wouldn't do with another "lesser brand" clutch. Unless they design ones for trucks differently, I don't think fast firm apply is the ticket for getting an extremely heavy vehicle(K5) moving.

    I have the three finger clutch in mine. I was told after it was installed that the diaphram clutch is smoother and lighter (pedal pressure). Sure wish I would have known that earlier...

    I believe they could use either one, but stock there were only two sizes available AFAIK, and I think the small one was 10.4", which I've only heard of for cars, even though they could get a larger clutch as well. In other words, stock truck clutch is probably the larger of the two.

    Go with the Centerforce. They are a great clutch setup. These clutches have weights which increase pressure as your RPMs increase, so on long hills and stuff it will not slip, this doesnt help much on the trail though, unless you are deep in a mudpit (which you have been known to do) and can get your RPMs up. Now the nice thing about this is decreased pedal pressure. I still would look for a hydraulic setup if I were you. Remember me on the Wall? I held that clutch for 10 mins and was wore out afterwards, you rarely see Mudzer back down. LOL ... Just kidding Glad you got this truck, it was a steal for sure. Keep me posted and email me if you have questions on how to do the swap.
