Your challenge is that there are only three gear sets available for that rear, 5.14, 4.57 and 4.11. The 4.11 would be the most highway friendly but they are very hard to find.
Your best bet might be to look for a Dana or GM 14-bolt with a gear ratio you like better.

It's true. I really don't do anything but browse the Internet looking for trouble... | | |
