    Clutch Questions...Help!

    Ok, so I'm getting a Hendrix Clutch/pressure plate. I've decided to go ceramic on one side, and organic on the other. (to not be obnoxiously grabby)
    Thomas says it's of the LS7 type. I'm also getting a billet flywheel (same as Spec) which is 16 lbs. to go with it.

    So here's some questions for the experts.......

    1) Will I have to get a LS7 slave or can I use a LS6 slave?
    I'm under the assumption that the LS7 slave will not need a spacer, but the LS6 will? What part numbers am I looking at here?

    2) If spacer is needed, does anyone have the dimensions of one? (so I can get one machined) I need diameter, input shaft hole size, width, etc.
    Or am I forced to buy the Katech one?
    Also, does it go on the inside by the throwout bearing?

    3) Has anyone heard of these guys? I wonder if they would just sell the slave by itself?
    http://www.corvettedoctor.com/CTSV_Z06_Clutch.html

    4) Where's the best place to buy the slave?

    5) I've heard that a "notch" is needed, but some have said it's not....does it depend on which slave you use?

    6) Does LAPD have the best remote bleeder?

    7) Is it mandatory to change out the slave at all? Or is it just good insurance to change out since you are in there?

    Sorry for all the questions.....I like to learn as much as I can before diving into installs. I figured with all the brilliant minds on here, we could eventually get some answers, and maybe bring up things that weren't thought of already. Thanks in advance!!

    Hmmm, I just went with the Monster Clutch stage 2.5. http://www.monsterclutches.com/level25clutch.html

    SNL Performance installed everything with no problems. I was expecting a lot of issues.

    Good luck.

    Other vendors on this forum are expected not to post in a thread that you make. If someone is talking about your clutch and another member posts up alternatives however, they're not breaking any rules at all.

    The Mods are here to keep everything clean, friendly and on topic- we aren't the thought police and we aren't here to prevent people from discussing alternative products.
    Rest in Peace, J.D. (aka Dirt_Cheap_Fleetwood)

    It's ok, settle down. Others can talk about your competition.

    By the way, are your clutches still renamed "birds of pray" clutches?

    Re: Clutch Questions...Help!

    Lolly if you are going from a LS6 setup to a LS7 equivalent, then you must change you slave as well... or get a spacer... (it's good insurance to change is anyways.... even if you didn't have to)

    Luke has the LS7 slave. I have the part # and price if you want it..

    I also heard a notch is needed... then I didn't. My understanding is that if you are going LS7 type slave, clutch, and flywheel then no cutting is needed... but just in case be prepared to take 1/2" off one side or the other !!!! have that sawzall ready baby!!

    I'm not sure on the bleeder... but whatever you end up finding and using, I'll be totally ready to shamelessly copy cat you. There are a bunch of guys on here with them so I'm sure they will chime in.... hopefully



    I'd say take lots of pics... but you are the one person I don't need to say that to in these boards... good luck!

    I wonder if there is one way to route it so that no notch is needed, like more room on one side of the trans/firewall/whatever....

    Lol, no that's totally cool....I'd rather everyone possible chime in, so we can all benefit from the "best" setup.

    I guess I'll get the LAPD, since nobody else has any suggestions

    Good call. As long as you have a competent shop doing the install you should be good.

    Good luck.

    Re: Clutch Questions...Help!

    A DIY clutch job is a big undertaking. Make sure you have access to a lift, multiple transmission stands (to support both the driveshaft and trans) and plenty of time.

    Re: Clutch Questions...Help!

    I did mine on jackstands and I can tell you, you want a lift lol But it is doable. You will need somebody to help get the trans back in. I had my dad with a jack under the tail and I held up the front and stabbed it in. That Tremec is heavy when your on your back. I pulled by myself. Knees under the tail and just slid it back and caught it. Not advisable if you aren't somewhat stong lol
