Glad you like the Quaife as it appears to be our only decent option at this point. No way I want a lunch box locker for this use.
I know what you mean about Torsen. I was so hopeful for that diff, but as the years dragged on, I lost faith. Since you say you've heard that they may actually be going for it again, I'll send them another email.
Thanks for the info on the TrueTrac. I figured it had to be to good to be true.
My FX4 LII came with the Torsen in the back which I really like, so I think the Quaife/Torsen in the front would be a pretty decent setup. I know I'm still not going to go everywhere my buddies go with Detroit's front and back, but then they don't use their trucks onroad.
I'll definitely ping this thread again in the winter to see how it's working out for you. It's my understanding the the helical LSD will not affect steering in 4Hi in the snow, and may actually improve it.
