4.70 or dual t-case?
Ok, I just got back from Moab and my stock gearing is not going to cut it. My clutch overheated on Pritchett Canyon and I had to be towed part way by a Jeep (not good!). I know that dual t-cases are probably the way to go but it will cost alot more that just installing a 4.70. Any advice would be great.
I guess if I decided the 4.70 wasn't enough I could go with dual t-cases later.

Doesn't hurt to start with the cheapest most effective option?
duals you're gonna need new drivelines, adapter, all sorts of bs.
My vote is on 4.7 with twin stick. Want lower, add the second case. Seems the logical "path" of upgrading.

i love this guy. he is like that voice in your head. not the little one that whispers "nooo save your money. put it towards your home loan." he is the one screaming in your head 24/7 "JUST DO IT!"

I've already got the twin stick and love it! I think I'll go with a 4.70 and start looking for a cheap transfer case. Looks like a 4.70 is pretty simple to do and a dual sounds like a good winter project.

You should be able to find a donor case for about $100
here is a gear calculator that you can play with to figure out crawl ratios:

personally I am happy that I took Brian's (waskillywabbits) advice and did the duals and 4.7 at the same time. after wheeling my truck on 3 runs I like the gearing selection.
I thought about just doing 4.7's but I am happy that I did not. 4.7 low range in between some obstacles would have been just too slow, even in 5th gear and some times the trail I could not use high range as it would have bogged the engine in even in 1st.
2.28 low range comes in handy. I don't use double low very often but it is fun when I want to
with my set up I have 2.28 (34:1), 4.7(71.49:1) and 10.7 (Double low 163:1) available so with the stock 3.90 diffs I can do quite a bit.
single 4.7=$350
duals
adapter: $350
crossmember: $200-250
donor case: $100
Drive shafts: $100-300+
23spline tailshaft: $150'ish
single case definitely cheaper, but I am glad I waited and did it all at once

I agree with ocdropzone. When i first read your post, my thinking mirrored yours in that the price difference made me lean toward the 4.7 gearset. But i thought about a trail i was on last year, and the logging roads between trails. I was in 4low for miles! But high range was to bogged down. If i had 4.7gears then, I would have had to use high range because i would have been to slow otherwise. My own thinking is to get the duals for myself, because you just have so many more gear options then.
