to Marland. Lockers, lift, wheels/tires, gearing pretty much in that order is what I'd do. The biggest improvement is a locker, makes a big difference on where you can get. Now that you've done that you'll find that you are too low so a little lift will help that issue. Next up the tires are now too small gotta fix that problem. Now with the bigger tires you will be a little under powered, you may want to consider lower gears in it while you are doing the locker. You can go with ultimate's but from what you are saying just go with 4.7's in a single case. Doing that is less expensive and also eliminates the expense of duals, cross members and drive shafts.
