Southbend DD?
I ran the 12 puck one for a while and used it for just about everything. Not sure what I have now, but pretty sure it is a 12 puck LOL The biggest difference was when the sprung hub was introduced. That made towing a snap with the double disk. All the sprung hubs I have done engage smoother than an FE
They are the kind of thing that sometimes you can get by without replacing them for a while, then just out of the blue they are done and you are stranded. LOL They do not always give a warning before they go. I strongly recommend them with a 3600 or heavier clutch. Come'on Jason, just whip out the plastic. LOL Or, tell Nelson to pay for it.

Im also running the Sprung Hub 3600 12cb and love it! Its not grabby at all and it shifts pritty dang smooth and it will also shift pritty quick but if thats what your lookin for id go with the 6cb.
I have a 3600 sprung 12cb clutch. I didn't install the new hydraulics when I did the clutch. It was difficult to get the clutch to disengage without the upgrade. Almost like it was still slipping abit. I also had to push it 'through the floor' it seemed. The upgrade got rid of this. The clutch is quite a bit stiffer than stock. I do notice it more as all of my driving is in LA traffic. The clutch is manageable towing and backing a camper up a hill. Once it was a little bouncy but with a bit of throttle it smoothed out fine. For me if I had to do it again, I might go with a 3250 but the 3600 has never slipped.
