I built up #95 and it has dual cases in it with stock gearing. I am running stock 4.10 thirds and have 38" tires. I have a set of 4.7 gears in the shop NIB and I cant make myself put them in there. I just have not seen the need to use them. I ride with a buddy that has dual cases with 4.7's in the back and 4.88 gears and Im always hollering at him to get out of that slow ass shit cause he always rides around in triple low.

How often do you guys run the triple low? Im more of a flogging type person....not the intricate crawl and find the perfect line. I just gas on it till it hops around and finds a line that it gets up!! LOL!

Another reason I cant really talk myself into putting them in there is I got a bone stock 87 4runner waiting SAS. I thought about just putting the 4.7's in it and wheeling the piss out of it.

What do you guys think?

I have the near the same set up you have. 38's, 4.10's, and dual cases. I had the stock gearing in both cases until a couple of months ago. I now have the 4.7's in the rear case. For me it was well worth the effort of putting in the new gears. I do a lot of gear selecting while on the trail. I like having all the options. See if you can drive some one elses rig that has the lower gears already installed. You can then decide for yourself.

Well I could drive my buddies rig and see I guess but he has 4.88's. Not that much difference. I dont have gear selections. I only have 1st, 2nd, 5th and reverse in the tranny. I hate shifting gears! I used to own a Peterbilt with an 18 speed so I kinda got enough of that shit.

Currently I am running 40's, 4:10's, and duals with 4.7's in the rear. I have only been able to drive it for about 30 min on the trail, so I can't help alot. But, there are times when low range is great (2.28) but usually the 4.7 (or double on stock geared crawlers) is ideal for most trails. However, I have noticed that the double with 4.7's and 2.28 has given the right wheelspeed without slipping / riding the clutch. Ie; The ability to use 2nd in low/4.7.

But like I stated earlier, I have only been able to drive mine about 30 min.:mad3:

Non stop. double low with 4.7's and use the transmission gears. Running 5.29 diff gears, I've been jumping between rear case low and double low when bumping.

Your clutch is real happy this way.

BTW... I'm running 37" Krawlers.

Well final drive in 2.28x2.28 with first gear is 83 to 1. 2.28x4.7 in second gear is 94 to 1.....not that much lower. Easier on the tranny running them in the lower gears too. I dont wanna be floggin on it in OD! LOL!

Im listening guys.

if you arent finding yourself wanting to use lower gearing, then you arent wheelin in the places where you need lower gearing. make sense. i see you are in n.e. texas. big sandy perhaps? anyways, there are no rocks near there like we have in socal. so build to what you wheel, but if you ever come out to the west coast, 83 to 1 sucks for a crawl ratio with a manual tranny.

i love me some 229 to 1. and if i am hauling ass on the trail, i do the rear 4.7 only with the front case in high. but its a bumpy ride.

Go 4.7's. That way you have more options :). I use 4.7's a lot but when it's dry and I'm in a technical rocky section I let the 10:1 do it's job. For trails I normally run 2:1. I never touch 1:1.

Well we have Barnwell Mountain but the only place the Ftoy has been is Clayton, Oklahoma. That is hands down the best wheeling around and some of the best in the country IMO.

My yota's got the duals and 4.7's, 4.10s and 35's

for a place like clayton I would probably do alot of the trails in just 4.7 and when I got to a big climb/obstacle I'd just flip the front case in if needed and then back out again afterwards.

One thing you have to remember in that LOW of gear is that it can break things just like bumping it in higher gears. It can crawl itself into a wedge and just snap outputs or ring gears with no problem. I let people drive my rig alot and especially my wife that isn't so good with a stick, she's actually won women's comps without really being able to drive a stick but with the low-low it drives itself. We have unmanned races at disney from time to time. I don't like people that don't know what they are doing to drive in low-low though, you can see the truck "load up" when wedged and you have to be quick to let off to avoid breaking but at the same time you don't want to push the clutch in and let it fly back down the hill, exploding your clutch

Your current double low is 5.19 (2.28X2.28=5.19) Not that far from 4.7. If your in double low you have some idea of what the 4.7 case will perform like.

If you add the 4.7 to your rear case it just gives you more options. 2.28 / 4.7 / 10.7 / hi range.
Your current options are 2.28 / 5.19 / hi range.

I will say that my car with 37" tires in double low with 5.29 in the diffs is too low for anything except very technical crawling. I typically run around in high range. Then drop to 2.28 then 4.7 if needed. when I am running a technical line or navigating cones I use double low first gear. Once I clear the gate or line its back to 4.7 or 2.28.

Man, your calling these things a car is killing me. I admit they kinda look like one, but "a car on 37's" just doesn't sound right.

Back to the subject at hand, I agree with the usage of the gearing options. Between the wifes 4runner with dual 2.28's, and my flatty with the 4.7 single case, the gearing options is nice. Both have the same axle gearing / tires, but in the flatty, in low I would have to run 3rd anywhere that it wasn't technical, where with the duals, just kick one into high. Having the 4.7/2.28 option just makes matching rpm's with speed easier (if you consider remembering which shifter / gear works best at that speed).

I really want to be like those imapalas and caprice classics I see running around with more ground clearance and almost equal tire size to my car. I hope to have huge chrome rims and low profile tires by the first werock event:flipoff2::flipoff2::flipoff2:

Maybe then you will call it a car.

Those cars are with the big tires and wheels are called Donks you bunch of uncultured hillbillys:flipoff2:

In So Cal it's called a Hi-Rize, but I prefer Dumbass. $10,000 wheels/tires on a $800 Caprice.:confused:

I have 5.29's and 2.28/4.7, and sometimes I still want lower gears. I would rather have a sandwich with everything on it then a plain sandwich; I can always pick off the stuff I don't like.

Now that is funny right there and maybe part of an up and coming sig. Thanks!

Also you can flog the 4.7 harder the than the 2.8-2.8 with out breaking the input shaft.

I use the 1:1 in the TCases when I want to do 70mph down a dirt road. I use the 2.28:1 when I'm just cruising around on the moderate stuff. I use the 4.7:1 when it gets a little technical. And, I use the dual low for the really technical stuff. It's nice to have so many options. All the gear selecting isn't that bad. You just anticipate what gear you need and go with it. It's no big deal to be in double low and 4th gear in the tranny. Just take the pickle and lettuce out if you don't like them.
