Got a reply from BT pretty quick. Here's what it said.
Thank you for contacting Belltech,
Well, we're not saying that it won't fit, just that it is not designed around
the 4 wheel drive. Also, we manufacture nothing for the front of the 4 wheel
drive. The choice is really up to you.
Have a great day!

So, yeah, I think they would work. It's kinda odd though... I can't seem to find too much info or reviews about them. I''m thinking maybe more people go with 2" shackles for $50-75 rather than 3" leafs for $330. I wouldn't even consider if it my stock leafs were not in the shape that they are...literally. If my stock springs weren't misshapen I think I would just yank the OL for the free 3/4" drop and call it a day.
I wonder how they would ride? In what little I could find, a few said they were stiffer than stock but most said they were softer than stock. I would think they would have to be softer. There's only two springs in the pack!!
I'm probably wishful thinking anyway. $330 is a lot to drop when I can just leave it as it is and likely not have any issues.
