ls1forlife1

Hello,

I am looking to do a clutch kit and slave cylinder on my stock 2004 LS6 CTSV. I wasnt planning on replacing the flywheel because the car only has 50k and it is just a daily driver. I get 19mpg around town, i dont beat on it. My issue is the slave or the pressure plate now, its still grabs wonderful, just having some issues going into first. Sometimes I have to really pump the clutch and I bleed it numerous times.

Can anyone suggest where to buy? I am looking for OEM or a good quality OE.
The car is bone stock, so I am not really looking for a ls7 swap

Is it completely necessarily to change the flywheel too? I just planned on doing the disc, pressure plate, pilot bearing and slave....

Thank you all so much!

Getting rid of the POS "dual mass" flywheel is the biggest excuse for doing a clutch job.

thank you for the suggestion, but I think I would like to keep this car as stock as possible. I would have bought all the parts from the dealer today but it was over 1000$, I thought that would have been absolutely stupid of me.

Most of the aftermarket stuff for this car is cheaper than staying OEM.

Is it good quality? They want almost 400$ for the slave cylinder.....

Better quality.

Thank you all so much the help.

Can you guys recommend manufacturers? I would like to purchase tonight

Being that my car has 53k miles would you recommend swapping the flywheel? Or can I just stick with the one in my car now?

As long as the rebound in the fly wheel is still there you wouldn't have to swap it unless you wanted to upgrade. I'd still say get rid of the +40lbs stock dual mass piece of crap, If you have 50K on that thing it's probably going to go soon if it hasnt already. Single mass flywheel is the way to go on these cars.

can you recommend any parts specifically to use? maybe a setup you are using or have seen used with good success?

I'm running a Katech LS9X clutch/flywheel with a stock slave. It's a ZR1 twin disk clutch with a single piece 12lb flywheel. I love the way it drives, taking all that weight out the driveline gives you a much better throttle response imho. Check around, and I'm sure others will chime in with their selections and the results. This thread has a lot of info on the matter.

If I were in your shoes, I would do the LS7 swap. It's all OE parts and they work. You wont have to worry about the flywheel coming apart and a little better performance too.

ls1forlife1

thank you all so much.

I read that they have to pump the clutch a few times on a cold day with their ls7 swap? I am having to do that now...I am trying to fix that issue.

All this shim talk...does the shim go in between the slave cylinder and the trans? or between the slave cylinder and pressure plate? Is the shim even required?

no shim needed with the ls7 swap if you replace everything, as seen in the threads above....

When you pull your stock flywheel (if you haven't already) check the play between the to sections just for kicks. I still have mine sitting around to show people, it wobbles and there is zero rebound. Getting a smooth start was damn near impossible with mine.

ls1forlife1

but some of people say you might need shims for that setup. I will most likely just keep it all stock if i can find the whole kit cheap. either I do that or I sell my car for 15000.

Anyone want a 04 CTS-V for 15000? 53K miles. still perfectly drive-able.

if you buy just the clutch keep and keep everything else stock. Your gonna need a spacer

ls1forlife1

well I might just buy a clutch disc, pressure plate, slave and pilot bearing from GM. Will I need a spacer then??? Is there a spacer in it from the factory? Where does this spacer go?

I heard a lot of good things about a ls7 set up. But I read a few things about the clutch having to be pumped on cold days or sometimes. I have this problem now, I am definitely trying to fix it. I just want the car to drive without issues. Im not looking for a clutch to hold more power. I daily drive the car, I do not plan on ever modding it.

I would give this guy a call tomorrow.

I purchased my LS7 setup from him and he put together a list of exactly what I needed. Good prices too.

if your having to pump your clutch pedal, that sounds like a hydraulic issue. Might be your master that needs some attention
