    i read the post about the 3:62 gear set for the 203, but not much was said. what do you think of them? where is the "wagoneer machine shop"

    I don't think that anyone here has any "first-hand" experence with them in a K5.....I thing it's about $1000 plus a core charge (you send them a 203 and gearset, they send you a different one all machined and ready to go)

    I know that a lot of folks are excited about it, but $1000 is still $1000 more than most of us have laying around.......for now it's just good to know it exists, and we can each plan accordingly! [​IMG]

    I don't have any problems with the 3.6 gears, I'd like to see a few sets out to be really sure about the durability but those guys use their trucks hard for sure. What I'm not totally sold on is a 7.2 low gear, but then I wasn't too sure about a 4:1 low till I built one. I know some rigs that need the lower gear. Bigger tires with hwy diff gears and poor 1st gear ratios in the tranny make t-case gearing really shine. The big thing is deciding if you really need it. That turns the new "ultimate" transfer case system into a $3K unit if you buy all new, around $2K if you scrounge parts. That's getting steep. We can put a 203 in front of an Atlas which gives basically the same gear options but maybe less strength overall?
    Best thing to do is try the Doubler with 4:1 and see if it does if for you. If not, get the deep gears.

    Yep,

    For me the "beauty" of that 7.2:1 setup is the ability to keep my otherwise "useless" 3.73 gears and 38" tires.....and loaf along the highway at 75mph turning only 2500RPM !!!!

    The price of that complete package IS expensive.....but so is a 700R4 tranny and TWO sets of diff gears....! (in my case [​IMG])

    I used to think that sliced bread was the "best thing"......now I figure the best thing is the ORD Doubler/Wrangler 3.6 Gearset !! [​IMG] ........I can't afford bread now anyway.......!

    Ok, maybe this is a stupid question, but the 3.6 gears would be contained only in the ragebox portion of the 203 so I could add them to a doubler later? I noticed in another post it being mentioned the entire 203 would be mounted in front of the 205. Just trying to get this right.

    Also you mentioned an Atlas behind a 203 range box in a Doubler. How much stronger would a 32 spline 205 be vs. a 32 spline Atlas. I've seen approx 900 ft lb rating on the Atlas and 1100 on the 205, but this may not be right.


    Thanks,

    Ryan

    Ryan,

    I can't answer the spline question, but as far as the 3.6 gears....they ARE in the 203 box. The "catch" is that the 203 housing needs some machine work for those gears, so you need to send yours in as a "core" to Wrangler. They send you one that's already machined and ready to go.

    So I guess if money was tight, you could conceivably run ONLY the 203 at first, and then add a 205 "doubler" later on.....

    What is so cool is that with those 3.6 gears you actually get 3 crawl ratios.....7.2, 3.6, and 2.0 !!! (When you add the doubler of course!) [​IMG]

    With a standard "Doubler" setup you end up with 4.0, 2.0, and 2.0 AGAIN! Since each box has the same 2:1 ratio, you end up with the same ratio in two different lever positions (203 Lo / 205 Hi) or (205 Lo / 203 Hi)

    Does that make sense.....? [​IMG]

    Greg's right the 203 could be used by itself but I don't know that I would do that to the poor little chain.
    I think it's neat to have more gears available but in the real world the 3.6 is pretty close to the 4:1 that we have with the Doubler and I think that's going to be the general use gear.
    As for the atlas vs 205, the 205 wins every time. I've heard the torque numbers you gave from Advance and have no reason to doubt them, at least in their relativity to each other. I don't think the 205 blows up with 1100 ft-lbs applied, so I'm not sure what those numbers represent.
    Only advantage I can see to using an atlas instead of the 205 is that the gear reduction will be farther "downstream" in the drivetrain so you'll have a lot less stress on the Doubler shaft than you would with the 203 low gears. I'm guessing the torque rating on the 205 makes up for it, and the common availability of the parts.

    &gt; I've seen approx 900 ft lb rating on the Atlas [...]

    Where did you get this spec? I phoned Altas and asked them that specific question and got a "duh..." back. I also asked them what the GVW rating for the case was, plus max rated input RPM and they couldn't help me on any account.

    That's what a rep @ AA quoted me for the rating on the Atlas. I don't remember his name it's been a few months ago.

    Ok so let me get this straight. With a 203/205 doubler and the low WMS gears for the 203 I have 4 gear options right? 1:1, 2:1, 3.6:1, 7.2:1 is this correct. Heck just thinking about it I'm confusing myself. Somebody give me a thumbs up or down on this and set me straight....../forums/images/icons/crazy.gif

    I think you've got it.....let's figure out the combinations:

    NP205 (Hi) with NP203 (Hi) = 1:1
    NP205 (Lo) with NP203 (Hi) = 2:1
    NP205 (Hi) with NP203 (Lo) = 3.6:1
    NP205 (Lo) with NP203 (Lo) = 7.2:1

    That's correct as far as I can tell....... /forums/images/icons/smile.gif

    The name is Wagoner Machine shop, not Wrangler. They are located in Claremore Oklahoma. The really do build some stout rigs. They can be seen in the recent fourwheel drive magazine's. I think Peterson's did some coverage on Mark's Toyota, John's blue jeep is also in the issue somewhere climbing the waterfall at Disney. Check out thier website. I just might have to start saving up for the lower 203 gears.

    Anybody know if these guys have a web site? I did a search but couldn't find anything.
