Congrats. Though, you'll never want to wheel without them again

. I hate the stock tcase in my 99.
In my old 87, I found the two best mods I ever did were dual ARB's, and Dual cases with 4.7's in the rear. I could never decide which one I liked the best, so I just rated them both number 1.
Dual cases makes wheeling a ton of fun, IMO, because you can really concentrate on the line, how the truck is moving, and, when you aren't sure what you are doing, being able to go really slow is very nice.
One of the unsung great parts of super low gearing, ( I don't know if you got the 4.7 set or not so this may not apply) is that when descending ledges, such as those found in many of the back roads of Moab, and even some here in CO, you can put the truck in double low, and first, and then let the clutch out and ride the brakes as the back tire comes off the ledge, allowing you to crawl down, and when the bumper touches, it is a soft kiss rather than a kidney shattering slam.
