well, i am entertaining thoughts of low geared transfer cases... not quite sure which way to go here... i have always leaned toward the atlas cases because of the gear drive, but i guess i will be into drive shafts, and everything else if i go that way.... so in order to properly get an atlas in the jeep is going to cost about 2500 bucks!
tera on the other hand will set me back about 1300 bucks including the 2w low. (would i ever use this?)
i have, however been reading some bad general feedback about all tera products. what can you tell me about their 4:1 kit?
:wave:

ATLAS

Dont fu(k around . . . get the Atlas and dont look back, you know you want to. :D

what he said!!! twin sticks baby!!!:yay:

Erik, getting driveshafts re-tubed or whatever you call it isn't that expensive. or atleast that's my belief. I'll be doing one next year... not sure if I'll do the 4.3 or 5:1 (yes they have a 5:1 from what I understand).

You know I have the tera lo. It is good but for the money, I'd look at an atlas (gear driven). I got the deal of the century on mine, that is the only reason I went with the tera lo.

Yep, if you can hold out until you save enough money, go for the Atlas. The only reason I went TeraLow in my 300 was because I got smokin' deals on my parts.

BTW, Crawltech (http://www.crawltech.com/) has great prices on the Atlas. Call them for a better price than they have on their website.

I love my tera low, then again because I don't go hardcore just a trail rig and good deal on the tera low.
save some $$$ and get the atlas, you got 4 disc brake you can use the atlas to turn your rig in tide turn.

my opinion

Do you have an SLE & driveshaft set up currently?

yes, i have the sye on there.

Most guys I know that run an atlas stick with the 3.8. The other gearing is too low and it over powers your brakes making it way hard to stop. Not sure, maybe that's just with an auto tranny.

Nailer, I know someone that might want to buy the SYE Tcase till he can aford his own Atlas. Which SYE & Driveshaft. I'm in socal too.
Might sway the vote?

Brian

this transfer case thing got put on the back burner for now... it will happen but i have to swap out my engine first, and a few other things.
thanks for the offer.. and it is the aa/tom woods set up.

It depends really on what tranny you are running, If you have an automatic, I would stay with the 3.8, If you have a manual, I would get the 4.3... I wouldnt go any lower.. I think the 5.1 is really too low, unless you are a competition guy, OR are running like 307 diffs..

5.0:1 too low? Are you guys ill? (as I wave my hand in front of your face to see if you are in a zombie trance). There is no such thing as too low.... Unless you are racing in low range maybe?

I agree!!! I have 4:1 and 4.10's (66:1 overall), with 31" tires, and I am still geared too darn high! With the 35's that Erik is running, I would go strait for the 5:1, with 4.88's or deeper in the diffs.

The 4:1 is pretty good for moderate trails (3.5 - 4.5), but it still makes it hard to go slow enough over the really technical spots of many trails.

Slower is better!:D

you guys are making damn good arguments for an auto.:):yay:

i've got a 4L60E sitting in my driveway.


but, it's out of my brother's truck, so you'll need to take it while he's not looking :D :D

it's even got a new input seal :8

I've got one of those 4L60E's sitting in the Jeep. Sexy looking thing too.

Yea, a automatic will help a bit, but I don't like 'em off road. When I come idleing up to a big f'in rock, I don't want to have the jeep stop when the tire hits it, making me use the skinny pedal, which then causes the jeep to "lurch" over the top of the rock, making me hit the brakes to get it slowed down again.....I prefer it to just keep idleing along at it's 2 mph, right up and over the rocks. Much more user friendly. It is also nice on those steep decents (such as Lions Back or the Luge bypass), not having to ride the brakes the whole way.

The key with the manual is that you gotta have deep enough gears, which is not always easy to do with the short wheelbase (no room for the second transfer case).

I dont have this problem with my auto. I've come up to many a Big f'n rock and it just chugs right up, no lurching or stopping. Then again, I do have some pretty deep gears in there. :D

I heard that the Daimler-Chrysler designers got tired of Tera transfer cases grenading and went with the NP241OR instead.

A few totalled Rubicons are beginning to turn up or you can get them new. Hope you find this idea interesting.

If you can find one of the NP241's out of a rubicon for a good price, that is a very viable option. Might be cheaper than putting a SYE and 4:1 kit in a doner 241 yourself......but buying a new one ("241OR" as DC likes to call them) is very expensive. I read somewhere that it would run you in excess of $2500. :eek:

I'm going this route with my jeep. I've got one coming from JB conversions.

http://www.jbconversions.com/pages/nvg241OR/index.html

The price shipped to me in CA is $1,850

It includes the right yokes for the TJ

I was looking at the SLE and the tera-lo but this looked like a better deal.

Should have it Thursday:D

that looks cool, but.. i think i'm still going for the atlas. it is about the same price. actually i can get the atlas for less than what you paid for that jb case.
i am leaning toward the 4.3, but considering the 5.0
thanks for all of the input on this thread so far :) keep em coming!

care to share where?

jason laliberty at groupbuy.com
1700 for the 4.3 with shifters. i got this price a couple of months ago, so it may have changed a bit... but if you are really interested, brian, maybe we can negociate a deal for 2?
i think i will be ready in a couple of weeks to a month...

i made a mistake on the price... it is 2015 for the 4.3 with the shifters, and 1700 for the 3.8 with shifters. SORRY

Wow. That is much better than what I heard they were gonna' be. For that price, it isn't so bad of a deal.

I would still go for the 5:1 if it were me though. :good:

2250 FOR THE ATLAS 2 5.0 with the stronger output shaft...
brian? are you interested in buying a couple of these? :wave:

sorry erik. I can't make that kind of commitment (sp?) at this time.

well, the decision is made... anyone else looking for an atlas, let me know. i have negociated a grat price on a 5.0 with the upgraded output shaft. the order will be processed in the next couple of days, and i should have it well before christmas :)

CONGRATS ERIK!

Thats awesome :)

Tam

thanks, tam! i cant wait to get it ;) do you need one? :D
really, any one else in the market for one of these... let me know. i am very sure i got the best deal available on one of these.
serious inquiries only :wave:

Nice!!! You're gonna love it when you get it installed!

Congrats on the Atlas!


Myself i'm going to go with 4 to 1 kit.

As far as the 2-lo:

This is useful when you're trying to make a sharp corner while crawling along in low range. You can shift on the fly to 2-lo, go around the corner and shift on the fly back into 4-lo.

Crawl Ratio:


For the Crawl Ratio (forward and reverse) you would care if you four wheel in rocky, steep terrain. The slower you can go over jagged, bumpy areas, the more likely you will get past without damaging your vehicle. Crawl "movement" is calculated at 750 RPM and is measured in Feet Per Second.

Everyone should be concerned with the Highway Speed results, unless you trailer your four wheeler wherever you go. This computes what speed you would be traveling at with the transmission, final drive ratio and tire size of your choice. Highway speed is calculated at 2000 RPM and is measured in Miles Per Hour.

When all is said and done i'm shooting for a 70:1 ratio with my Jeep.

check tommyjeep.com for info i'm going with his set-up, or at least trying to.

Just wondering, have you ever wheeled with anything with that approximate crawl ratio? I am at 66:1, and find it a bit on the high side. I went from ~34:1 (with a automatic) to 66:1 (manual) and loved it, for about 6 months. Then I started finding myself wishing I was closer to 100:1. The more I wheel it, the more I wish the gearing was deeper. Whenever I wear out the 31's, I'm really gonna be whining for the deeper gears.:rolleyes:

Point being, make sure that the 70:1 is deep enough for you. It would suck to get it all set up and then find out you want to do another gear swap.

according to chris, with the 4.88 gears, atlas 5.0, and 4.88 gears i am around 96 to 1
i think that is what he said.... i dont know the formula.

1st gear x t-case low range x gear ratio = final ratio

I wouldn't use an Atlas or Tera-low's gears. If and when my Dana-18 ever grenades I'm going to replace it with one of Jack O'Brian's Rock-Eater Dana-18/20 hybrids. They are extremely strong, you get twin sticks, you can get gearing as low as 4.1 to 1 (I would more than likely shoot for something in the 2.72 to 1 range; yeilding a final crawl ratio of 93.5 to 1), and I can retain the use of my Warn overdrive unit. They run somewhere in the neighborhood of $2,000 with case exchange. O'Brian is a retired NASA engineer that has wheeled his entire life, and decided some years ago to build a better Dana-18. He's redesigned the bearings in them as well to reduce the whine that they characteristically emit at roadway speeds. Old-school Bronco guys have been using them for years with no complaints...

Nailer...
If I'm not mistaken you have 4.0L engine that mean you have ax 15. Its first gear is 3.83.
if you're using 5.0:1 and 4.88
your final ratio will be 3.83 x 5 x 4.88 = 93.5 to 1

If you have an Atlas II 5.0:1, AX-15, and 4.88 gears:

Your transmission's lowest gear ratio is 3.83 : 1
Your transmission's highest gear ratio is 0.79 : 1
Your transmission's reverse gear ratio is 4.22 : 1

Forward Crawl Ratio: 93.452 to 1

For the amount of wheeling i do and the land i wheel on 70:1 will work fine for me. I do have a buddy who is at 70:1 and i have wheeled with his Jeep, this is what i have based my build on.


Things of course could change, they seem to always do, but for now 70:1 is my goal.

Good deal. It is nice to have someone with a setup similar to what you want, that way you can get a better feel for how it will perform.

Personally, 250:1 is my goal (not in the heep--wheelbase is too short).
