Source for new Viscous couplings

[xr4x4ti]

I am hoping the group knows the best place for a new viscous coupling for the 1372/4472 T-Case.

I just did the DaveP test and mine will easily turn 90 degress in less then 6 seconds at 40 ft-lbs. It is actually a bit tough to get to 40 ft-lbs. I guess it failed open which would explain why I was spinning the rear wheels like crazy at the track last week

Does Borg Warner actually still make them? Anybody sell the OEM unit? Anybody sell an upgraded unit that is a bit stiffer?

Here is what I found so far:

This looks to be OEM?

This says that it is aftermarket.

This place sells them on an Ebay store

Anywhere else?

Best?

I put one in from Cobra Transmission just before Carlisle. I only have a couple hundred miles on it so I can't give much feedback.. It did survive Auto-X at Carlisle and lots of launches afterwards...

Its not OEM... IIRC the box said Made in Taiwan.

We have them in stock.

Re: Source for new Viscous couplings

I got the one from cobra transmission after numerous recommendations on here from people. Unless you're ready to pay about $500-$800 for a NOS one from a gm supply site, the cobra one will do just fine.

Dunno if it'll help but here's mine when I got it:

This is great info.

I actually ended up getting a rebuilt unit from STE.

It was a good price. What was more interesting is that since they rebuild them they can adjust how much fluid is inside and what viscosity it is. I got a unit that is suppose to have the stock specs, but in the future they said they would be more then willing to make a custom one for me that was stiffer to get more torque transfer.
