Im running a Southbend Dual disc with a 3250 plate load and 6cb's. sprung. from what i have seen and heard from Peter the 12cb's dont slow down as fast as the 6cb due to rotating mass. so that will enable you to shift faster. let me know if i can be of any other help.

I love my HMR Street Drag...I have not had it to the track but around town it shifts faster then stock IMHO
it is a 6puck solid hub
SBC or Haisley and you will be happy.

I love my VALAIR #3600 DD, it has held everything that I have thrown at it, with out a problem. It is also very smooth when pulling trailers. Give them a call and talk to Dan or Kevin and they will hook you up, just tell them Chris with Death Row Diesel told you to call!!!

You get a little rattle from them, and a stiffer pedal, but it is not bad at all. I like this one better than the single Organic/Feramic that I had. Much better Clutch for a Daily Driver.

do you have any performance mods done to your truck? from looking at your sig your truck is mostly stock with the exception of a better lift pump.

yup just a little added noise and stiffer pedal. but both of those are to be expected when stepping into a diesel truck.:thumbsup

Robert, I dynoed at 446hp/859tq at ART this year, and am working on getting a Smarty for my truck right now! I do run it at the track a little, but not too often.

How are you pulling 446hp with just the intake, exhaust, lift pump, and Quad race?

I was running the quad race on pressure only, stacked with a diablo preadator on extreme.

depends on what you want to use the truck for mainly.
you said you want to launch like me in your first post. im staying with a 3250 pressure plate for quick release. but im sure i could still do it with a 3600.

Mostly daily driving and haulin a small load but want the ability to launch for the weekend. Sorry to drag this out but now you really have me wondering about a few things. Please bare with me. What exactly is plate load and what does it do for you. What is the difference between sprung or not. Last, what are the pros/cons of having more or less buttons be they ceramic or organic? I know thats a lot but thanks in advance.:thumbsup

not a problem. the Plate load is determined by the which pressure plate you get. they are rated as follows 3250,3600,3850,4200. there are some in between but these are the popular ones. in short it is the applied load when clutch is released.

the difference between the new sprung hub and older ridged hub design is the newer spring loaded hub is much quieter. the springs dampen the vibrations.

the difference in the buttons from 6 to 12. the 6 button clutches are suited more for racing they are a bit more grabby as compared to the 12 button. the 6 has less rotating mass to help shift faster. the 12 button is really suited for a smoother release and geared towards towing and sled pulling.

hope this helps. if you have any other questions feel free to ask. im sure there will be others who can add to this too.

in short it is the applied load when clutch is released, not, it is the clamping pressure on the discs when it is engaged.

well you could say it like that, but when a clutch is released it is not engaged. at least for those of us in the clutch business

Thanks RobP you're the man. One more question for ya... At what horsepower level do you think it is neccesary to upgrade the input shaft on our six speed. The auto guys always do it but is it needed for us?
