Installed the SBC DD Max Street - Performance Organic kit last night. It took about 3 hours total including flushing my uuuggly BLACK'nd DOT 4 out. So far I only have 100 miles on it, so no power to it yet. The clutch pedal feel is identical to that of the ferramic kit. Enguagement is a tad smoother than the ferramic kit so it is not quite as grabby, but I suspect over time to smooth out even more. I can't wait to do some hard launches once it is broke in. I will post more as I put more mileage on it.

Why would you do hard launches on a street organic? The ferramic would have had a lot better chance lasting while doing hard launches. Or are you just testing it to see what it will take before it breaks.

Testing it but will most likely be a permenant solution for me since I drive 80 miles a day in stop and go traffic here in Denver. Good for 600hp so the ocassional racing and dyno days won't hurt it. I don't do any sled pulling with my daily driver. The feramic kit was excellent but a bit grabby for stop and go traffic every day.

The ceramic of mine engauges very very nicely I think. Pulled a 20K trailer this weekend and didn't give me a shaking feeling when still taking off in 2nd when stopped.

The ceramic engauges smoothly and a little more forgiving than the ferramic. I am certain with time the organic disc's will smooth out nicely. I put the power to it this weekend and it put it to the ground!!! AND OF COURSE NO SLIPPING AND NO HARD PEDAL!! Yet another great clutch offering from SBC!

How is it backing up. does it shutter?

No shudder on back-ups. I haven't had it hooked to the 5th'r yet so we'll see how it performs with some weight on it. As I was driving in today I noticed it started to smooth out a bit. As I said before it should just keep getting better and better!!

How is it compared to the cerramic dd?

Organic discs should be smooth right from the start. There is no reason organic should get better. Actually no clutch should get smoother engauging with wear but some will get worse.

I previously had the ferramic kit in my truck but did do an install on a ceramic kit and drove it. They honestly feel very much the same in terms of engagement. The ferramic and ceramic are a bit more grabby than the organic discs.

I backed my trailer up a steep incline trying to get it into the shop and was slipping it most of the time as to go slowly and I thought it was very smooth with just a hint of grabbyness. Mine has not got any worse or better really other than I think it is alot quieter now than at first when in nuetral. When the clutch is in it is a lot noiser "wisking" than when in nuetral.

Well don't know what to tell you Mac but it is...take it or leave it. I would like to believe members here would be more inclined to believe those of us who have actual experience with the products SBC is producing. But thanks for enlightening with you wisdom.

Duramaxed out I have more experience with clutches than you ever will and also have some experience with south bends products. I've personally had south bends products in my own personal duramax and they also make clutches for other brands that I have dealt with. I was sharing actual knowledge of all types of clutches since you were misleading the public into thinking a clutch should get less grabby with time. The truth is as a rule a clutch will not get less grabby or jumpy engauging with time. I didn't say yours didn't but I did say that it doesn't usually happen that way. If you would like I can explain how the clutch works and why it should not get less grabby with time or wear just let me know.

:hug:

Your experience is vast and great....far greater than mine no doubt....but "you ever will" might be reaching just a tadd that is unless you took the time to get to know me and ask questions before slandering me. Your knowlege allowed you to create a better alternative to the DMF and allow diesel enthusiats to pursue big HP. Funny thing about your posts though, you seemingly always have to know more than the next guy...including Peter. I have a little experience too, but my past experience is not relivant nor similar to what I found with this kit. Share with us your experiences and knowlege with the new Organic materials found in the disc SBC is now putting out. In my conversations with Peter these are new materials in this disc to the organic marketplace. I believe this new disc is not available in the Dodge or Ford kits yet.
Tell you what, the moment you post something postive about the SBC products as opposed to your constant bashing and share some positive usable information for DP members we can continue our trip down education lane and you can Skool me anytime with your vast amounts of knowlege...until then you can keep your clutch lessons and negativity to yourself. Just an FYI, I have never "mis-led" the public or spoke negatively of the Mac's kit...why because it is still a great alternative to the DMF. It's okay to admit someone besides you can build a better mouse trap!

Actually I prefer....:beerchug: !

Duramaxed out I have never bashed a SBC product. I don't personally see any reason too. I don't care whose clutch your talking about or what material new or old as any disc wears it will have more contact area which can cause less smooth engaugment. I don't have any problem with SBC or Peter I believe they offer only the best quality products they can produce. I personally believe Peter is a great honest guy and definately much more knowledgeable than I am about clutches but that doesn't mean that I don't disagree with him sometimes.

Actually I prefer....:beerchug: !

THats probally better i must have missed that one!!!!!!!

Please guys, lets keep this discussion positive and informative and not try to turn it personal and or bait each other :)

Thanks Rat...will do! Nothing but love and fields of daisy's here.
Moving on...the clutch is holding great in terms of HP I have thown at it! No hard pedal and no slipping what so ever. I will hopefully be able to step up the power again this weekend and do some more testing before the dyno day on the 22nd for the real test!

Good to hear new stuff is working well.How much rwhp will it hold? As much as my DD Ceramic? Just wondering because a second D-Max 6spd may be in the future :D .Not sure how soon yet but I'm thinking about a dually.

Thanks it is working great!! The organic street will hold 600+ HP. I plan on taking it to the limits as it seem quite capable of more. The ceramic we set you up with is definately more than capable of anything you put to it. I almost got a dually with ZF...it was identical to my truck same options, same color but I stopped hauling cars so I decided to against it since they get a few less mpg. They are really...really hard to find with the ZF! Let me know when you are ready and I will keep my eyes peeled here in Denver for you. So how is the clutch holding up for you? Are gonna try to come out next weekend for the dyno day?

Yeah,I'm planning to come down. I was hoping to get one of SD's lift pumps before I dyno but that's not happening.I just have a bunch of parts and no cash :o: . My clutch is holding great. I was playing around the other night and I broke the tires loose when I shifted into 6th :D at 3k rpm. Absolutely no slippage :cool: .

duramaxedout, Is there any 2500hd zf's in the denver area right now? I'm looking for a 6 speed, and they are hard to find, I will take one with low miles or maybe even brand new.
thanks,
Phil

Duramaxphil: was there any on autotrader that fit the bill? Michael probably knows of a few down there but there is an 01' or 02' CC LB 6spd 4x4 north of Denver by Longmont. The box is a little dinged up and it has gravel chips but it looks clean inside and I believe it has bucket seats :cool: .

I have been driving a fairly heavy truck with the ceramic disc kit. I have also driven duramaxedout truck with the the dual street disc. They both sound the same (same price, too) and the installation process is the same. His seemed a little grabby as did mine when I first got it installed. Since then the CB can still be grabby but is not because I have had enough time driving it that it now is almost reacting like stock (except for no slipping).

I suspect that there are two issues that could result in some differences. 1) would be the install tq on the flywheel being symetric on each bolt. I actually marked each hex bit and flywheel once all were tq the same and then made sure that each was turned exactly the same amount. 2) how you drive it. I don't always start just by releasing the clutch pedal. Adding some rpms and slowly releasing the clutch seems to work around the grabbiness and if I do this periodically, even just a clutch release seems to be less grabby that early on.
