I'm running a 94 pickup SAS, 22RE, 5.29's with 35x14.50 TSL SX's. I mainly snow wheel, so I wanna keep it light. But I cant decide between the 4.7 t-case gears or dual cases. I only know one guy personally that has the dual cases and he says to go with them... but thats probably what I would say too if I had them. So what does everyone else think!

 

your probably going to get mixed responses here as well. I personally have a single case with 4.7s and they suite me just fine. A couple of advantages of dual cases is you still have to option of running with one case in 4lo if you need some wheel spin. With duals you also have the option of 2wd lo( this can be achieved with a single case using twin sticks). I mostly chose the single 4.7 case option for money reasons. With duals your drive lines need to be lengthened/shortened, a dual case cross member is needed, you need a second case and the adapter as well. I dont have any negatives to say about either set up but like i said i went with a single geared case because its cheaper and its a direct bolt in with no mods needed to the drivetrain. just my $.02

 

Yeah the single case gears are going to be less money and less work. All I really want is the low gearing, I dont care about having 2LO, the truck crawls around just fine in 2HI with the 5.29's.

 

i don't have rather yet but the 4.7 just makes more sense!

 

I have 4.7 gears and I love them.....for what I use them for, if you do mostly snow wheeling, I would suggest duals though, because you are not going to be crawling in the snow.

 

What do you mean by I wont be crawling in the snow? I dont mean to insult, but have you ever snow wheeled? All you do is crawl. When I snow wheel my main goal is to not spin the tires. If I do break traction, I back up and get a little momentum and go as far as I can again.

 

I have been thinking the same thing, single 4.7 or dual stock cases? The single 4.7 is cheaper and easier, but you lose stock low range. The dual cases give you a lot of flexibility with shifting, but there are a lot more steps to getting it done. In my situation, I already have two transfer cases (a forward shift and a top shift) just sitting in my garage, but no extra time/money yet for this project. I think I'm gonna hold out until I can do the dual cases.

And anyone with manual hubs can have 2WD Lo. Just unlock the hubs and shift into 4Lo!

 

I have been snow wheeling before, I have done it with and without my 4.7 gears and I think it was a lot easier without my gears. Just my opinion I guess, my 4.7 gears work best for situations where I am going downhill or rocky sections where I need to go extra slow and otherwise I would be slipping the clutch.

For me personally, if I did mostly snow wheeling I would want duals.

 

if time and money is an issue now. just do the 4.7 for now. down the road you can still dual it and have the best of both worlds and than some

 

I've got duals and love it!! I wanna put 4.7's in the rear case so I'd have the best of both worlds. like the others said though, alot of work and more money for drive lines, ext...

Do Both!!!

 

I see what you mean by still having the stock low range with the dual cases, but with 4.7's I still have 5 speeds in the transmission to use, I'm not sure how strong 3rd 4th and 5th gear is though....

 

4.7 low rang e between obstacles even in 5th is slow and you might end up slowing a trail run..more money but I vote duals

 

i have had both setups and now that i have duals with 4.7's in the rear case i would never want to go back....i am not limited to much, i have wheeled in the snow, mud, sand, and rocks and now that i have duals my options are not so limited i can wheel it all and wheel it well i do ps.......you will need wheel speed in the snow at some point or you are not wheelin hard enough

 

If you can only do one you have to go with the dual cases. You will end up with a lower crawl ratio for when you're crawling through the powder. But you will still have your stock case for when your trying to power it up an icy hill.

 

Next question, is there only certain t-cases I can mate to the existing one? Like a top shift or something like that?

 

Your rear case must be top shift. But your front case or crawl box can be either. I'm gonna guess your 94 is a forward shift. All you would have to do is find a used topshift and use your case for the crawl box.

 

i dont know about you, but i hate getting stuck and i hate breaking ˟˟˟˟˟...duals just make life easier for you and your rig... build it and build it right the first time...

 

btw i got duals 4.70 mc chromos. they are...daddy...
