looking to add va box. dont know whats a good name clutch to go with. any help? thanks for the input.

You a few options here either south bend clutch or Macs clutchs. What all do you plan on doing with the truck? Are you going to sled pull at all or just drive around?

just drive it........ pulling a little every once in awhile. nothing too heavy. but i do plan on driving it like i stole it.

Then a single disk is all you should need. Unless your are going to do any Sled Pulling at all.

I agree with jjgmc. Recomend you order a Con O clutch plate. It will tow trailers fine and handle additional power and still engage without any squeal or grabbing. Will last a long, long time if you drive normally.

kziggy: I sent ya a PM.

Hey John, what is a "Con O" clutch plate?

MaxRock

SBC term for organic clutch plate.

I am in the same boat I am saving up for a SBC clutch and I have all intentions of buying the Single disc Feramic button clutch. I have been reading that if there is any plan to do any sled pulling that I should go with the Double disc. if the HP and torque ratings are the same on both clutches why would I need to have the DD clutch? is it because most people slip the clutch so much when launching? a friond of mine has a Single disc in a Dodge that is tuned and he does not slip the clutch hardly at all on the launch just rolls into the power once he is already moving does anyone have a little explaination for me? I would like to pull maybe once or twice a summer at the little fairs not the big competitions and I am just looking for a little input...Thanks

Deadeye will be able to give you exact #'s but Peter @ SBC told me the Single Disc was good for 500rwhp and the Dual Disc was good for 1000rwhp.I don't remember what buttons he was refering to. Ceramic,Feramic or Centered Iron. I watched two guys at a sled pull with SBC single disc clutches in Dodges. The one {a 1st gen'er} got about half down the track and it let go completely :eek: . The other guy had an 01' with 650wrhp and he just kept stalling it cause he was too scared to slip it. I went dual disc for that reason,cause I planned to run at least 450rwhp {which I am over} and sled pull. I'm glad I did cause I'm shooting for 600+rwhp now.

The Mac's clutch you can switch from D/D to S/D or S/D to D/D.

i was told i have a brass button clutch can anybody tell me what that is and if thats a good or bad thing

Brass, Thats a new one!!! If your clutch is OEM It is just a plain old Organic disk, No buttons!

so when I had my DMF replaced and I bought the clutch, Pressure plate, and Con Bearing did they put this new "brass Button" clutch disc in? is it rated better than the old organic style? that part number for the one that is on my invoice is 12582859 for the plate and 24232434 for the flywheel I was told that the flywheel was an updated version when they did it does anyone know anything about this?

Sorry, I been busy for a while. The issue is that all clutches can be used for sled pulling, at least once !!! The problem is the heat and the strength of the whole kit to hold the rwhp without slipping, which then increases the heat which eventually trashes the clutch and will cause some impacts on the PP, FP and flywheel buttons. 01Duramax6spd was correct about the hp ratings. But a sled has a huge potential impact on the drive line (and suspension, and . . . )

In my opinion, if you got the $ and you want to do competitive sled pulling, get a feramic DDC. If you are only going to do a few sled pulls but you want to put a lot of extra rwhp on your truck than the ceramic DDC is the next option. If 500 rwhp is enough for you and you are not going to do ANY sled pulling then a SDC will be fine. The choice of the clutch buttons is just a matter of $ and rwhp.

Hope this helps.

John

great info thank you Deadeye.....

can anyone tell me about a brass button clutch or did the previous owner tell me a bunch of crap. he said it was installed at the dealer when the truck had 40k miles on it. any help?

What he Said......:confused:

I found some talk of brass button clutches for import cars. The way it sounded they grab pretty well, but I would have no idea. I myself have never heard of using brass, but I'm by no means an expert.... Maybe it would be possible to have one custom made?

SBC does not use brass on their diesel clutches. The buttons on the ceramic clutch plates and on the flywheel look like brass but are not.

New to the Diesel Place. We have an '04 and a half GMC Duramax 6 speed. I'd like to know if anyone knows what the stock clutch will take Horsepower wise. I just put an Edge programmer in it and I was just curious about reliability.

mine took edge on level 5 all the time 20k miles before the flywheel took a dump.

i'd say the stock parts are good for stock horsepower.

your stock flywheel will go out fairly early regardless of using a tuner. If you run it at 90-110 hp it will not smoke the clutch but if you go higher it will. I know because I did the same two years ago. check the threads about the zf6. If you look as some way back you will notice on a poll, at that time, that 72% of zf6 guys had problems at that time. since then many have replaced their flywheels and clutches. send me a pm if you want to talk.
