: Flex Disc / Drive shaft Coupler Camaro part number

The Short:
I have a 2005 CTS-V. Is this the correct Camaro part for replacing the drive shaft coupler:

92249108 (http://www.tonkinonlineparts.com/p/__/COUPLING-KIT-Propeller-Shaft-Pinion/6371924/92249108.html)

The Background:
I just purchased a 2005 CTS-V a few days ago with 81k miles. The diff swap was done by the original owner. Only other obvious upgrades are B&M shifter, Lingenfelter CAI, and Magnaflow exhaust.

Looks like all the soft stuff in the driveline is worn out (rather expected), and I've ordered the Creative Steel kit already. Since the shop will be dropping the diff to do the bushings, I ordered the GForce axles to be swapped in. With all the work being done, I figured I might as well replace the driveline coupler (flex disc, six-shooter) at the same time. I've had the car gone over by both the local Caddy shop and a very experienced GM Master Tech. Neither has called out this as an issue, but since everything will be apart already...

So, I have pretty well exhaustively read everything there is to read about drive shaft couplers on this forum and the LS1TECH forum. It looks like for a Gen 1, I have the following options:


Complete OEM Drive Shaft (not really an option)
Aftermarket Drive Shaft (probably out of budget)
RevShift Flex Disc (and possible driveline alignment work)
2010 Camaro part



The last two options are the ones that I prefer. I'll be calling the shop on Monday to see if they would be comfortable doing the tranny alignment and installing the RevShift part. Or... I'll be fine getting the Camaro part. I don't really plan on doing a bunch of HP upgrades on the car anytime soon. I want this to last a long time and don't want to introduce additional wear into the system.

So, with all that said, is the Camaro part listed above the correct one? Should I expect a GM Master Tech to be able to align the drive line well enough, or should I be looking for a specialty shop? (I'm in Austin).

Has anyone actually used the Camaro part with success?

I don't recall hearing about anyone trying it. Are you sure it cannot be purchased separately from the dealer? Give Luke at Lindsay Cadillac a call and see.

Just got off the phone with Luke, and he hasn't heard of anyone using the Camaro part.

I'm wondering if the RevShift product would do okay since I'm remounting everything in the drive line anyway -- motor mounts, tranny, diff... Of course, that's all with CS parts but they should be the same spec's, right?

I'm not planning on doing any HP upgrades in the near future, so perhaps I'll just order the Camaro part and give it a go.

Anyone have an opinion? I'm very new to this car.

The Camaro part has been mentioned in the past, like in this thread (http://www.cadillacforums.com/forums/2004-2007-cadillac-cts-v-performance/226621-bad-ass-couplers-soon-reality.html) and this thread (http://www.cadillacforums.com/forums/2004-2007-cadillac-cts-v-performance/254627-driveshaft-coupler.html). Revshift said the parts are different, but a couple of folks said they were the same. I don't know what the right answer is.

Looks like I'll play the guinea pig on this one. I found a local dealer that will let me special order the part running the risk of a 15% restock fee. That's about what I'd have to pay to ship it back to someone if it doesn't work, so that's a wash. Since everything will be torn apart next week, I'm going to include this part. I'll go take a look at them both with the tech once it's all disassembled and decide from there.

I'll let everyone know what I find out.

Honestly, if anyone else has dealt with this and found a solution you like, please let me know.

UPDATE:

When I looked at the parts side-by-side, the new part (number above) did look like it had slightly different metal collars. However, the dimensions of the part seemed to match. I've had it on the car now for about 125 miles, including a fair amount of highway driving. No vibrations at any speed. For those of you looking to replace the stock part with a similar stock part, it looks like this is a good option. I wish there was a Creative Steel option that was in-between this part and (what appears to be) the very unforgiving RevShift part. Since I'm mostly stock, I didn't think I needed an upgraded part here. The stock one looked worn, but no tears after 81k miles on the original.

So you did go with the Camaro flex disc? Did the drive shaft need aligned? I was going to attempt this job on my own. Looking at the Rev Shift instructions the exhaust needs dropped to gain access to the drive shaft. Then make sure to have a mark to assemble the drive shaft back in the original position.
Thanks for the info. Mine needs changed due to vibration issues.

Yes, I used the Camaro part. I didn't take anything to get realigned, and I haven't had any issues. I did this right after I purchased the car. It had 81k miles, so it was time for all the soft stuff in the drive train to be replaced. So, I took the "while you're in there approach" to save on labor. All at once I did:

* Creative Steel motor mounts
* Creative Steel trans mount
* Creative Steel diff bushing and diff block
* GForce axles
* Camaro drive shaft coupler (guibo)

I've been quite happy with the results. However, everything was loose enough in the car when I bought it that I didn't really drive it until all the work was done. With just over 100k on the car now, I'm quite happy with how tight everything still is. The sales guy at the shop loves it when I bring my car in for him to work on. He used to have one himself.

Thanks for the info. I am going to order on tomorrow. Glad it worked out for you.

I just Installed this flex coupling 92249108 (http://api.viglink.com/api/click?format=go&jsonp=vglnk_14267054358168&key=99b92d6e152eb9d1dde89f41fbc2db4b&libId=i7f3kp940100272e000DA17zci0n9ma5f8&loc=http%3A%2F%2Fwww.cadillacforums.com%2Fforums%2 F2004-2007-cadillac-cts-v-performance%2F380585-flex-disc-drive-shaft-coupler-camaro.html&v=1&out=http%3A%2F%2Fwww.tonkinonlineparts.com%2Fp%2F_ _%2FCOUPLING-KIT-Propeller-Shaft-Pinion%2F6371924%2F92249108.html&title=Flex%20Disc%20%2F%20Drive%20shaft%20Coupler% 20Camaro%20part%20number&txt=92249108) in my 2005 CTS-V and it fits perfect and is too made in Germany. My vibration is now totally gone feels like a new car. My old one did not look bad but compared to the new one it was a lot "harder". I'm guessing that because the exhaust system runs right below it over time it baked it"

The only bad /scary part is removing the exhaust system to gain access to flex coupling bolts make sure to spray some brand of rust/penetrator before you begin on exhaust bolts

First I've heard about the flex disc getting hard over time but it makes total sense. Thanks for posting....

Good to get confirmation of one that fits, with the part number and everything. Thanks!
