I have a GM LS6 cluch (flywheel, pressure plate & disc) that I plan on installing in my 2002 Z28. Although the car only has 28k on it and the stock clutch is fine for around the town driving, after my intake and headers I find it has a tendancy to slip going into 2nd when I get on it or if I go to the track. I was planning on reusing the pilot bearing, throwout bearing and slave. Does anyone feel that the throwout bearing and slave have to be upgraded as well?

I replace the TO bearing and slave on all clutch swaps. They are cheap insurance that you don't have to do the process over again a month later due to skimping on parts.

BTW your 02 came with the LS6 clutch from the factory.......

Really, my car has a LS6 clutch in it from the factory? I was looking into clutch solutions on-line a while back and heard the LS6 clutch was an upgrade for camaro/firebird drivers with stock LS1 clutches. Not a big deal though, saw it on Ebay and the guy who had it turned out to live a few minutes away from me so I got it pretty cheap. Always good to have a spare if the price is right I guess but I asume I will eventualy run into the same slippage problem... what year did the factory start putting LS6 clutches in LS1 cars?

The shop manager at MTI in Houston told me that my 02 camaro did not have the LS6 Clutch in it, even though I was pretty sure it does. (he has never seen my car),
makes me worry that a manager at a big shop like that would be wrong,
I decided not to take my care there, after he and I had that discussion.

I would reccomend replacing the throwout bearing since you are already there, like was said, it's cheap insurance. Also, have you considered replacing the master/slave cylinder of your clutch, and doing the drill mod? I hear it makes shifting the t56 much better, and it's not too awfully expensive

I didnt think the drill mod was needed after 2000 cars....

Clutch that came out of my 2002 Z28 was GM P/N: 12581650 (Ls1 clutch) The clutch that went in is GM P/N: 12570806 (Ls6 clutch) feels much better so far.

As I could not get a straight answer on my 2002 Z28 clutch delema I sent an inqury e-mail to tech support at Fred Beans Chevrolet asking if my car came with an LS1 or LS6 clutch from the factory for those of you with mild engine upgrades who are considering using this clutch for low noise, stock pedal feel and driveability as I am. Here is his responce below...

"Anthony,

The newer Fbodies came with a form of the LS6 clutch but not the real deal. LS6 is really old news these days. Since September we’ve been using the LS7 clutch from the new 2006 Z06. It has more surface area and sustains more power and abuse. You can get pricing and final prices shipped on our site at www.fredbeansparts.com.

12571611 flywheel

24236500 clutch

14061685 pilot bearing

15046288 slave cylinder

thanks for the info, but quick response: It shows the throw out bearing being for a 6.2l diesel (not sure if it matters) and the slave being for a 2.2l.
Maybe those are interchangeable?

I'm sure those parts could very well work in more than one application. Basicaly this whole thing started because I threw a few bolt-ons on my car and found the slight increase in torque was causing my stock clutch to slip. I have a connection at my chevy dealer and was thinking of going with a GM upgrade to my car as I'm a big fan of factory parts when it comes to drivability as a good factory clutch should insure a smooth stock pedal feel & quiet operation.

I'm not makin big HP, I'm just looking for an upgrade. I heard that my car may have already come with the "LS6" clutch in it from the factory but I could not find any documentation to support that, only hearsay from other F-body guys. I researched it and found that there are indeed two different GM part numbers between the two clutches. A bit of work but I wanted to make sure before i stupidly invested in what i thought was an upgrade and it not turning out to be one.

My inqury to fred beans supported my theroy that the 2002-2004 Z06 clutch (12570806) is better than the stock "LS6" clutch (12581650) which comes in my car from the factory so I went with the Z06. We will see how much better it is as soon as i seat the disc in a few miles.

Hmmm, according to GMpartsdirect 12581650 is only a flywheel. 12570806, the Z06 clutch, is what Ill be getting.

The Z06 clutch I got... P/N 12570806 is flywheel, disc & pressure plate in one box, the box simply says "12570806 - Flywheel"

the 12581650 is all three parts as well, GM just calls the whole kit a "Flywheel"

I have the LS6 clutch/flywheel, P/N 12570806 installed in our 02 WS.6. When i took out the original clutch, i checked the part numbers on the flywheel, and pressure plate, and t he part numbers were exactly the same.

On an off topic, and found out i have an LS6 block in our car as well.

alamantia

What was the number on the pressure plate? Since I still have not found a definite answer or any literature supporting the difference between the two clutch kits anywhere I looked I believe the pressure plate should be the only difference between them anyway. I only have that one e-mail from Fred Beans Tech support saying the Z06 clutch is better. Out of all three parts the pressure plate would be the part that would generate the clamping force. I believe the only difference between the camaro and Z06 clutch kits is clamping pressure, not the flywheel and not ths disc, they should both be the same.

Again, not trying to start arguments, just trying to understand the difference between the clutch I took out and what I put in. So far all signs point to yes that I did indeed upgrade my clutch. I think the misconception has been that yes my car came from the factory with the quote-unquote LS6 clutch but the Z06 clutch that I installed is indeed an upgrade.

The car has less than 30k so I just reused the old slave cylinder, master cylinder, pilot bearing, throwout bearing, and rear main seal. They looked fine, no leaks. Aside from that initial new clutch chatter which we all know goes away once the disk seats, every thing is running great!

well been trying to figure this out, bought an SLP flywheel on ebay, great price, also won a pressure plate and disk separately with part number 731 on the press plate, does anybody know if this is the crossover partnumber for the 2002 LS1/LS6 pressure plate part number or what, i read earlier that the 02 came with the LS6 clutch but the true LS6 number was 806. so my question is does anyone know what the 731 part number is.? the guy selling the clutch says it came out of a 02 camaro.

hhidyhoneighbor

ok heres the scoop, Z06 vette pn 12570806
02 vette (non Z06) pn 12581650 which is what the chevy dealer is selling for oem replacement for an 01 camaro ( i checked at the parts counter today) guy looked at me like i was crazy when i asked if it was an LS6 clutch, guess he didnt know. anyhow what i was looking for is the Z06 part number. hope this helps other people out.

the 2000 camaro pn is 12572731 dont waste your money on it besides from gm parts direct its a special order item. so in regards to my previous post dont need the answer for the 731.

I ordered an LS6 clutch kit a couple of years ago and it was the exact same thing I had stock in my car.....

alamantia

iTrader: (10)

Depends on what you ordered, the Z06 clutch (12570806) is different than the stock camaro/firebird/C5 clutch (12581650) they are both made by LUK and look the same but are indeed different clutches.

hhidyhoneighbor

Just curious if anyone can confirm about the 731 part numbered clutch?
