All right guys I sold the w56 tranny I had laying around and now have a top shift transfer case laying around. I had a guy offer me 75 bucks for it. I cant decide if I should sell it or wait and use it for a doubler setup. My questions is for anybody who has ran the 4.7 and later swapped in a doubler to get the 2.28 gearing back? If I had the doubler but with stock low rage, would be enough that I would not need the 4.7 gearing all together. I have looked around here but can't seem to find any real help other than (yeah I did this or that and loved it or hated it). I am looking for more help in the advantages vs. disadvantages in just running the new gears vs. running a doubler, and why I would run the 4.7 on the doubler. Thanks for all your time and input. The guy who wants the Transfer case is wanting to come get it next week. I need to make a decission about it before hand. I don't want to sell it if I need to keep it for a doubler set up.

Depends on what kind of wheelin you do. 2.28 x 2.28 double low does really well and is slightly lower than a single 4.7 case. You can search the advantages vs. disadvantages of dual cases vs a single 4.7 case, but the only disadvantage to dual cases compared to a single 4.7 case is the cost, but in my opinion way worth it. You will miss the stock low range if all you have is the 4.7, you'll be going way to slow for regular trails and for intermediate sections of trail you'll want the higher low range. Putting 4.7's in the rear case of a dual case setup will put you around 250:1 crawl ratio in low low, this is too low for any thing but rock crawling. I have dual 2.28's and they have worked great so far and the difference between stock low range which is about 40:1 and my low low range, 100:1, is a world of difference, yet I still retain the stock 2.28 low range for easier sections when low range is just too slow.

So what specific questions are you wanting answered, and what kind of wheeling do you intend on doing?

I wouldn't sell the case, you can get more than 75 from it, and if you're planning on going duals, top shift cases aren't always easy to come by so keep it till then.

I am going with a single 4.7 for this wheeling season, but plan on going duals next year. A few members in our club have duals with 4.7s in the rear case, and I like how they perform on the rocks.

As for either selling your 4.7 gears and reverting back to stock, do you have the stock gears for the case still? Do you find your self needing more wheel speed then your single 4.7 case can offer you? Do you ever want to go slower?

Duals are expensive but worth it.

If you go duals do it all or don't bother, as it really depends on the wheeling.

Ftoy I sponsor has one case 4.7s and does great but it only sees competitions.

Trail rig of mine has duals, 4.7s, chromo output, twin stick etc and it is awesome. Drove around all day high low in 3rd/4th gear with few clutches. Get the right gearing and it becomes an automatic but with options.

Guy at my shop was just going to go one case with 4.7s. Let him drive my truck and went duals.

It's been said above. I run a 2.28/4.7 Marlin Ultimate and wouldn't have it any other way. I use every gear combo.

Thanks for the feed back guys. Well I live in Western Oregon. I wheel mostly in the Coast Range and have been to Browns camp. We some good hill climbs but mostly mud and wet slick rock. I am building this rig to play here but am looking at doing the Rubicon in the next couple of years. My concern is putting in gears that are too high and not having enough wheel speed for the mud. I don't want to bog down in the goo, but I want enough grunt to make it up some pretty steep rock faces. Thanks for all your thoughts and tid bits of info. I think I am going to hang on to the case for now. I like the 4.7 but think I am going to try doubling two stock cases, and if need be pull the rear one and upgrade to 4.7 later.

How much am I looking at for drive line mods after the case swap? Who did yours? Any recomendations/cautions to be warned about before hand?

So right now you do not have 4.7s or a dual case setup? In that case go ahead and dual it up

Na, right now I am stock in the drivetrain department. I have the 22re mated to a w56 tranny with a stock top shift transfer case. I also have another top shift transfer case sitting on my work bench. I assume I can mate two top shift transfers in the duel setup?

I had my driveshafts built locally. You should be able to find a reputable shop. Try to get them to use Toy U joints, some build with Spicer. Go with Toy double cardans front and rear (at the tcase). Just visit your friendly boneyard. The IFS DCs can be modified for more flex (it will be needed).

Your driveline angles will be much improved with double cases too, a nice side benefit.

Hey man I just bought a top shift case in Monmouth was that you? I almost have the crawl box assembled!

Yeah its me. Your runner looks sick. How hard was it too install that setup?

4rundog

Its just your basic SAS kit. Its not hard but is very time consuming! I have had a lot of fun modding the thing but havn't had time to wheel it yet.
