T-case OR 4inch lift ?

[ia yota]

lift!

[Rockcrawlintoy]

  Duals stocks is much cheaper than rebuilding or buying a 4.7. 

no it isnt. after doin the d lines and gettin a new x member it is more. however you have more gearing options. i also recommend this route also

[muddpigg]

Dual stock t-cases over 4.7.  I went with the 4.7 to begin with now have duals.  Some time a single 4.7 is too low and 4 high is to high, besides with 35" and 4:37 there will be more times when low is the only option for you.

lift it!!

post some pics of the 35x10.5 boggers I am thinking of getting a set and I want to see how narrow they are.

I have 529's with 37's and run a single 4.7 t-case and it works perfectly.  Been runnin it for years.  Works great in rocks and trails.  Just my

I could not agree more.  I have 5.29s with 35s, and I also run a single 4.7 behind and R151F in my 4Runner. This week, I am upgrading to a Marlin dual ultimate set up, but it's definitely NOT because I miss the faster speed "options" of stock 4 Lo gears (at 2.28:1).  Nope.  I am switching because I want to go slower, and because I now have the money for the crawl box and the drive lines required by a dual set up. 

Basically with a single 4.7 case, my truck ran at 20.64:1 in 5th gear in 4 Lo, and it ran at 22.8:1 in 1st gear in 4 Hi.  There's no gap; in fact, there is some overlap. 

I will go a bit further.  The final ratios for stock 4 Lo (at 2.28:1) with my set up spanned the following range:

5th gear -- 10.01:1  (almost the same as 3rd gear in 4 Hi)
4th gear -- 12.06:1  (almost the same as 2nd gear in 4 Hi)
3rd gear -- 23.28:1  (almost the same as 1st gear in 4 Hi)
2nd gear -- 33.05:1  (in between 3rd and 4th gears when using a 4.7 case)
1st gear -- 51.98:1  (in between 3rd and 2nd gears when using 4.7 case)

My final ratios with my single 4.7 case spanned the following range:

5th gear -- 20.64   (in between 1st and 2nd gears in 4 Hi)
4th gear -- 24.86   (almost the same as 1st gear in 4 Hi)
3rd gear -- 47.99   (in between 2nd and 1st gears when using a 2.28 stock case)
2nd gear -- 68.12   (lower than 1st gear when using a 2.28 stock case)
1st gear -- 107.16  (still lower than 1st gear when using a 2.28 stock case)

So when people say that single 4.7 cases are too slow, I am left scratching my head and wondering what I am missing?   It can't be the 1st and 2nd gears when using a 2.28 stock case at ratios of 33.05:1 and 51.98:1 because my 4.7 single case offered the respective ratios of 24.86:1, 47.99:1, and 68.12:1 in 4th, 3rd, and 2nd gears.   Unless, it's just me, and I need to develop an acquired taste for stock ratios like 33.05:1 and 51.98:1, I will remain at a loss.

Of course, when my dual ultimate is ready to roll, I am sure that I will try using the stock 2.28 ratios of 33.05:1 and 51.98:1, based upon the "because it's there" principle, but more than anything, I can't wait to double down and shift into the new dual ratios that span 47.054:1 through 244.32:1.

I am a newb so if I am missing something please enlighten me.

I could see an argument maybe against buying a 21 spline 4.7 gear set to run in a single case temporarily, which a person fully intends to use later in a dual ultimate set up without upgrading to a 23 spline 4.7 gear set in the rear case, but I don't think the 23 spline upgrade is necessarily required for that type of set up; it's just optimal.

one day ill upgrade my stock dual cases to a dual ultimate setup....one day

[oldyeller]

Well I ordered my 4.7Tcase today!

I'll give it a try?
And let you all know!

[4LoRunner]

gears skrew pro-comp

You'll be happy with the t-case.  Works great.  One of my buddys has 2 stock cases and my 4.7 single is almost identical.  You can always add a stock crawl box later if you so well choose.  But unless you wheel big rocks you wont need it.  Have fun, enjoy

try being in 3 feet of snow and trying to go in 4 high or trying to get over 30 in 4.7 case it wont happen. thats where the stock duals really shines.

First, let me say  on getting duals.

Since I have run rigs with both a single 4.70 t-case and now duals, I can say that somehow the translation from the mathmatical overlap in gears to the real world isn't quite what it appears.  Running in stock low range feels a lot more "relaxed" if that makes any sense.

No matter, you'll be happy!

[oldyeller]

After I get it installed I'll let you all know what happens!

Crankycrawler will tell you that gears go farther than ground clearance, at least in the rocks.  His rig was locked front and rear with a single 4.70 t-case when he was running 32 inch tires and a 1 inch body lift.  He was able to go everywhere I went in Moab except he high centered going up White Knuckle Hill (the long bed wheelbase made it impossible).

Gears give you the ability to control lines without bouncing so you can attack with a plan rather than just  and putting the hammer down.

I know I'm tired of the" Hammer Down" method!

Jon and rockcrawlintoy, I do appreciate the responses based in experience, rather than straight numbers.

oldyeller, I look forward to hearing how you like the lower gears.

My 4.7 tcase showed up today!

no adaptor? man should made it a dual ulty.


nice case though man

[oldyeller]

I'll try one for now! But you never know a guy just might make it happen!!!

[H8PVMNT]

You will love the 4.7s.  I have been running the 4.7 case for a few years now and all I miss is a higher geared reverse.  Who need to go 35 mph in low range?  Tha tbeing said I would love to do duals sometime just because it's cool!  Always keep you money in the drivetrain if you want to wax on the trail!

We have been reworking the stock springs lately on a few super budget builds.  This is our cheapo 3" lift formula: We just add home made extended shackles, one long leaf to the fronts, removed the overloads in the rears and replaced them with 2 or 3 thin leaves from old stock packs or whatever you can get ahold of.  Do the knuckle ball flip, use your rear shocks up front and find some longer rears off a wreck...  No huge flex but definately a huge improvement in flex and ride over tired stock springs and you get about a 3" lift for almost no money!

[Rockcrawlintoy]

.  Who need to go 35 mph in low range? 

i like to go that fast when im snow wheelin. esp on a powder day

[80_yota_pickup]

i like to go that fast when im snow wheelin. esp on a powder day

this is a very good point snow is a good time to have the high gear. that is why the duals are bad to ace!

[H8PVMNT]

Duals with 4.7s in one case would be ideal for everything, but in an imaginary world or under the hypothetical condition that they were'nt possible and stock low or 4.7s were your only options I'd choose the 4.7s  for all around wheeling.  If you are only doing high speed snow romps, stock low range gears are probably better...

[Rockcrawlintoy]

thats why i like to recommend stock duals u get the gearing of 4.7s if needed  and u also get stock low

[blackdiamond]

A single 4.70 case is much easier to install and probably cheaper for most people when you consider the adapter and drive line expenses.
