I don't know if it's been said, or not, and I can't be bothered sifting through all of the crap on this thread, but in lowering the front end, you might consider finding a pair of 2WD Trooper torsion bars. They are softer than the 4WD ones, and if you were to crank them down, they'd be tamer on the stiffness.

Also, you could replace your front shocks with Gabriel HiJackers, as they are air-adjustable. If you ran 'em at around 85psi, it'd be nice and soft.

I second the Valley Spring Works post made earlier. Just tell them what springs you have, and tell them how much shorter you want them to be.

The nice thing about TOD is that it'll matter less that it's lowered than it would on a traditional t-case.

Or, just disconnect your front driveshaft altogether. It'd net you some more economy and acceleration, especially if you don't use 4WD very often, if ever. It would effectively be a 2WD then, of course, but if you're using it as a pavement pounder anyway, it doesn't really matter. Another gain is that you probably wouldn't go through front tires as quickly, either. I dunno. Maybe it wouldn't make a difference unless you got manual hubs. It's hard to say.

You could always reconnect it if you go to sell it.
