Ok yeah I'm thinking about the southbend dual disk clutch.

Southbend is good stuff. What my Audi had, loved it. I have no idea what kind of quality their diesel rated stuff is though. I would start a new thread related to that specifically and see what other people with zf6's suggest for clutches.

My dad has a 1200 hp pull truck. and all he runs is southbend triple disk clutches and they last.
I really appriciate all of your advice and help.

:tu: Yeah, I think that you have your answer then. That's impressive. :s:

Any time, I have had so many people help me that the least I can do is help others.

I do the same towing you are doing and I had Power Hungry Performance install a 6 position chip and stage 1 injector for me. Milage when up from 13 to 17 completely empty and no trailer. Completely loaded down on 10 ton gooseneck milage went up from 9 to 11. Not much but every little bit helps.

My truck is a E99 F-350 Dually with intake and exhaust mods, gauges, injectors and chip. Just got the CoolMist Water/Meth injection and will install in the next two weeks.
