The dual ultimate is a dual setup with 4.7s in the rear case. Do what you want but this makes the difference on the trail. You don't have to beat your rig if you have gears. Lock it up then gear it. Bring a spare birf with you and tools. Gittinit runs stock birfs and does any excellent job. Don't drive like a clown and you will be ok.
Sounds good, I'm going to order up an adapter and 4.7 gears and get them installed. If money runs tight, I might just stay 4.10's, weld up the rear and buy an aussie for the front. The dual ultimate is enough gearing off-road with 4.10's and 33's.
Thanks guys for the input!!
