The picture on this one makes it look like you get a really cool looking clear one.

But here is the link on amazon for the other one, for future reference so you don't have to pay $200 now at the dealer.

Amazon.com: SGF GAH04-005 - OEM German Made Flex Coupler - Bolt Circle 105mm/Bolt Hole 12mm/Bolt Hole Length 35mm: Automotive
You can't get one from the dealership. Hyundai, BMW, Mercedes, ect only offer a complete driveline, not just the couplers.

Alternative, last stop.....

After having custom cast my own enigne mounts, then experiementing with different Urethanes on my AT insulators I will do this when the time comes

Industrial Urethane castime compunds,..2 part.

All you need to do is remove the old oem. Make a casting mold of the part. Then you can go to town and experiment on the Durometer of the new casting depending on your driving needs.

The new part will last forever, unlike the oem rubber stuff.

Both shore A abd shore D are superior in yaw resistance, tensile strength, impact resistance etc. You must decide on hardness versus dampening.

The cost would be 25% of the above oem replacement.

Daily drivers would be a high rated shore A.

A guy like Shorttrack would defintely go shore D, and not realy give a **** about a little vibration transfer.
Even a high rated shore D will have better dampening than a solid aluminum disc. It would fail before the Urethane, also Urethane is superior to aluminium in shock resistance.

Do these not have some sort of steel or kevlar based cord inside? If you look at the link I posted with the clear ish one, you can see more than just rubber or urethane in there.

If one needed to insert stainless sleeves, or a cross bracing that wouldnt be difficult. It would just take some dissection of the oem after making the casting mold.

They just look like bolt sleeves with washers just under the casting. It would require 10 grade or better hardware 12.9 if you can find it. From the looks of it your offering is a high rated shore A material I bet.
I'd use ARP stuff.

I able to toke the front one off without dropping the drive shaft unlike the rear. Maybe get a picture of the OE one? I've got mt old old ones out in the junk pile.

But there are manufacturer identifying numbers on them.

Better hurry if you want the Amazon ones. I ordered on 5/27 and there were 70 at the time. They are down to 13 now.
I ordered these couplers from amazon for $70 USD a piece and replaced them (results were spectacular). Amazon has a note from the seller (SGF / DriveShaftPro) that they can get more: "Usually takes 3-4 weeks for us to receive from Germany though. "

The coupler is also sold by PowerTrain Industries - About Us for same low price. Googling GAH04-005 helped find the best spot to buy.


As to my results - replacing these couplers fixed my considerable rear drivetrain vibration issue at 65-75mph. Had the issue since new in 2010, but could never get help from dealerships until I got fed up and found threads on the forum here with people confirming what works for some cases. My car drives like new now and I'm super happy I tried this.
