It doesn't sound like you need something a TON lower than what you've got now. I'd probably recommend 4.0's instead of 4.7's so that your only low range choice isn't quite SO low and is a little more usable all around. If you did a lot of rock crawling, then it might be another story.

Of course duals are the ultimate in all around gear choices <img src="/forums/images/graemlins/mrt.gif" alt="" />, but as you know, its a much more substantial modification.


And not that you have a choice, but 21 spline will be plenty for a 4cyl and single case. You would have to try REALLY hard to break anything in the t-case. The upgrades aren't really needed until you double up the torque in duals or put it behind a lot more motor.
