Quick question. Clutch related...
So me and a buddy of mine were talking about clutches and he posed a question to me that I didn't know the answer to.
He has an 05 Cavalier with a 2.2 F23 transmission. I have an 08 Cobalt with a 2.2 F23 transmission. Can you use a clutch for my Cobalt on his Cavalier and vice versa?
He mentioned that he had seen guys with 05 Cavaliers running the flywheels out of an 08 Cobalt before and was just wondering if the clutches would work.

I know when i had my 2005 2.2 I had issues with the cavy's throw out bearing that was shipped with my clutch so i swapped to a new OEM cobalt one and fixed my issues.. I believe TTR (at least they used to back in the day) sells the same clutch for the cobalt & cavailier. THey may have changed it after the issue i had as i made it very well known.. 
Well I don't really know if anyone else has ever tried the actual clutch from one to another. When I was asked it seemed like it should since its the same transmission, just as long as the input shaft has the same number of splines an the bolt holes all line up the same. At least I would think.
Well my reasoning for thinking that they may in fact fit is that the main clutch assembly (the stamped metal portion with the finger springs) is a very similar 6 bolt housing. The clutch disk diameter is 8 7/8". The spline number is 14. And the only difference is the spline diameter. On a Cavalier its 15/16" and on a Cobalt its showing 1".
That seems incredibly similar between the two.

Ok, so I called KY this morning and Summit Racing to ask them this same question. KY were kind of dicks on the phone, but I thanked them anyway and went on and called Summit. The guy there was really cool. I explained to him the information I was looking for and he pulled the information up on his computer.
Basically what he said was, a 2005 Cavalier with a 8 7/8" clutch diameter and a 1"-14 spline count was interchangeable with a 2005 Cobalt. He went on to say that his computer cut off model dates for the Cobalt at 2007. I explained to him that alot of people are advertising clutches being sold for 2005-2010 Cobalts with the 2.2L motor. He told me that if the clutches out were for the 2005-2010 Cobalts and that a 2005 Cavalier and 2005 Cobalt clutch were interchangeable, then its fairly safe to assume that the 2005 Cavalier clutch would work on a Cobalt as well.
So I got off the phone with him and did some more digging. Turns out that the Exedy Stage 2 clutch has a 25mm spline diameter. That translates out to like .984". All of the Cavalier clutched are showing a 1" spline diameter. So the difference between the two is showing .016", with the Cavalier being bigger. Chances are they are probably the same except for when they measure metric vs standard. Alot of the Cavalier measurements are in standard while alot of the Cobalts are in metric. So if the Cavalier is only 16/1000" bigger than the Cobalt, then it should work just fine between the two.
I have a couple more phone calls to make this evening one of which is to my uncle, who has been a master mechanic for over 20 years, before I'll be roughly 99% sure on this subject. I wont be fully 100% sure until I see one bolted up and functional. But seeing as how Cavalier clutch kits are cheaper then Cobalt clutch kits, I may give it a try and see what happens.

No I'm asking to find out what parts are interchangeable between the j-body and delta platforms because let's face it, there are only a handful of companies that make aftermarket parts for either platform. So if we have more interchangeable parts that opens us up more.
I get y'all are looking for the sale, and believe me, as soon as I get the funds for my build y'all are gonna get several grand out of me. Haha. But given that the Cavalier platform died 7 years ago parts for them are usually cheaper. So finding out what options we have available to us is a good thing since we're now a dead platform too.

I think there are things you are missing. Cavaliers were out for over 20 years. Cobalts only 5. More parts were made during the tenure of the Cavalier than have been made for the Cobalt. Plenty of companies made lots of parts for the Cavaliers before GM discontinued the line. Since there are still Cavaliers on the market and on the road, there must still be replacement parts for them available. So manufacturers who built the parts prior to the discontinuation of the Cavalier had parts stocked and after the discontinuation of it, didnt have to build as many parts to maintain the demand. Because of that, prices have dropped slightly in comparison due to the fact that the discontinuation of the Cavalier was more years ago then the discontinuation of the Cobalt. In years to come, as the supply of parts for the Cavalier goes down, we can expect to see an increase in the price of said parts.
It wouldnt be cost effective for GM to discontinue one line of vehicles, with a proven power and drivetrain, and introduce another compact 4 cylinder car and completely redesign the entire powerplant. It makes alot more sense that GM would continue to use the parts they had. Likewise, its also not cost effective for a company that manufactures performance parts for a specific platform to go "back to the drawing board" so to speak to completely redesign a new component of an existing platform just because the model name of a vehicle changed. In 2005, the Cavalier used the Gen 1 L61 motor with an F23 transmission, same as the Cobalt. So why would the clutch assemblies be different given its the some powerplant and the only changes are the vehicle aesthetics? Now, if its safe to assume that the clutch assemblies arent in fact different, then we can fast forward to today. On your own site, you have multiple drivetrain components listed as being for the 2005-2010 Cobalt 2.2L/2.4L engines. As Mkruley pointed out, in the early stages of the Cobalt, your company sold parts that were interchangeable between the Cobalt and Cavalier. So I think it would be fairly safe to assume using basic logic, that the parts are probably interchangeable and that its only more profitable and better for business to sell one product as two totally different applications.
I dont see why you are getting so worked up over people trying to see what is interchangeable and having options. I know that y'all try to corner the market on the Delta platform as one of the top distributors of parts, but its just odd. I find it even more odd that you are bringing up the fact that the KY clutch your company sells is the best on the market and that any thing cheaper is of worse quality. What makes all of this very suspect and downright laughable is that your own company sells cheaper knock offs of other known to work parts, they've merely been counterfeit and branded with your company logo. It scares me because by your logic, any knock off is of subpar quality, so what does that say about your parts?
This could have all been avoided if you had come in here with legitimate facts as to your claims that they wouldnt work other then a simple part number difference. Part numbers change. But you chose not to come in with measurements and facts and started trying to make it appear as though I am in some way looking for an easy way out, when in fact the exact opposite is true. Easy way out is to buy a known model specific clutch and install that.
Your companies antics and demeanor is strongly making me reconsider ever ordering parts from you or referring anyone that I know to further do business with you.

I wasnt talking about the KY clutch when I said counterfeit parts. I meant the sway bar, trans mounts, and turbo intake manifold yall sell. And as for polling people about the KY clutch, I have and they hate it.
Now being pissed at KY for their responses wasnt because he said it didnt fit, but because he gave absolutely no reason as to why it wouldnt, much like you havent either. But oh well, I never expected a company to be honest when they make a living selling counterfeit parts.

I called them because I figured since they were a smaller company then say Exedy or ACT, they might be more willing to talk to a customer. Unfortunately I was wrong.
Anyway, since no one can explain why a 16/1000" difference between the two is enough to warrant two separate clutch assemblies, I'll assume that its because yall just believe the bull **** being fed. So Im out of here. I'll let this die off because the only company contributing doesnt even know. Have fun selling your knock off parts guys. Hopefully that turbo/NA manifold hybrid direct Hahn copy sells all over the place. Just dont expect any business from anyone that I know.

? First off ky clutch aka Chris isn't a dick or an ass hole but when he is questioned on his knowledge he may come off as one. He knows his ****.
You want to know what it takes to run a Lsj/lnf clutch.
Flywheel
Clutch including pressure plate and friction disc
F35 trans and axels
Not sure on hubs and spindles but I'm sure them as we'll,
Linkage
More then you want to spend.
It's all different
As long as its a ecotec 2.2/2.4 it can be done I'm sure.

the motor and transmission in the first base cobalts was essentially just lifted from the cavalier/sunfire and dropping into the cobalts. the transmissions are the same. furthermore, gm has used the same 1" 14 spline input shaft right back to the fwd muncie 4 speeds in the first gm fwd cars. i used the same clutch alignment tool for my cobalt ss.sc as i did for my 86 2.8l cavalier. gm doesnt like to change things like this, if its not broke, why fix it?
the biggest difference in the entire clutch setup would be the hydraulic release bearing. the connection is different for the j-bodys, so you cant interchange those.

Ok, so another little update. I called my local GM dealer parts department today and explained the information I was looking for. The guy pulled both parts up in his computer and told me that it will work because the parts are exactly the same. He went on to tell me that from the dealership, they only use one clutch for the two vehicles.
So just to toss out the information for anyone who may be reading this, yes the clutch between a 2005 Cavalier and the Cobalts are interchangeable.
