    I'm pulling my motor soon to install heads/cam etc. Minus well replace the clutch. I'm getting wildly different suggestions on whats good. Some say organic, some say kevlar. Some say stock replacement, some say get a stage 123 clutch and learn to deal with its street manners.

    Facts: I will be about 400rwhp and tq. I drive more on the street than the strip. I do not want kevlar...it is not made to be a wearing material. Because of this it will tear up my flywheel/pressure plate. DO NOT WANT.

    After some looking, this looks like a good deal:

    http://www.jegs.com/i/Ram+Clutches/798/98516/10002/-1

    Ram HD clutch. Good for about 550hp, organic, and cost effective at $400.

    What do you guys run, and what would you recommend?

    If you have a lightened (drilled) pressure plate do not go kevlar. Kevlar requires the maximum amount of surface area to bite properly and with a stockish feel. I did a SLP lightened clutch kit (the pp was drilled around the outside to dissipate heat and make it lighter) and kevlar clutch disc. It was the most chattery aggressive clutch I have ever driven. I mean I could not drive it in traffic it was jumpy and grabby.

    Buddy with a stock LS1 did a stock clutch with only a kevlar disc and he loved it and it gripped hard.

    Saying that my buddy with a 396 460RWHP/460TQ LT1 uses a Spec hybrid which he likes. Two other buddies have used McLeod and when setup right with the adjustable slave have beat on for years with slicks and never had a problem.

    Centerforce and Ram I have no experience with.

    i run a ram powergrip HD with a stock flywheel. its worked fine for me, for the last 2 years.

    my car makes 405 rwhp, and has seen MANY hard launches on ET streets.

    oh, i had a centerforce clutch in on my old lt4 hotcam motor. it never gave me problems, but the motor was weak and i only ran street tires. but it treated me well.



    i have heard to stay far far away from spec.

    how are the street manners of the powergrip hd? I've been told to stay away from Kevlar because instead of the clutch wearing out, it destroys the flywheel and pressure plate

    I have ran a McLeod single disc on a full bolt on car, never sticky tires, but people have had good luck with these clutches. I've been realy happy with it, however about a year ago i think the disc got bent or somthing with the PP effed up, because it wont go into any gear at all when your at a stop. Already replaced the hydraulics. I haven't drove it in over a year, so when i do fix it i might just throw in a stock parts store special, or if i get abetter one, i'll get the 400 dollar ram setup. Ram's are prety good, especially for the money.

    its kinda hard to drive in stop and go traffic, but that probably due to my tune and cam more than anything.


    i have taken the transmission out 3 times over the life of this clutch, and it still looks brand new

    ever notice your flywheel or PP being abnormally worn from the kevlar?

    also im running OBD2 in my car so no matter how radical of a cam I run I'm sure my tuner can get it to perform like a new cadillac with EFI Live :)

    I have nothing to contribute to this other than I broke the clutch fork in half twice on mt lt1 t56.

    So I swapped to an LSx. :mamoru:

    to tell you the truth, i didn't know it was made out of kevlar.

    the pressure plate and flywheel alway looked fine, almost new.

    Bought a Duralast clutch at autozone, for the Valeo LT4 pressure plate. $200 there. Then bought a McLeod organic disc at summit for $170 shipped.

    $370 total, I got a clutch equivalent to $500 or more from competoitors. With any luck I'll sell the duralast clutch disc for some more money off :)

    duralast makes clutches? :ugh:


    there's gotta be another stamp somewhere on there.. majority of oe replacement clutches are made by only 3 or 4 companies



    it's cheaper to rebox em a lot of times. betcha money you have a perfection clutch in that duralast box
