    jb conversions just checked the site and it's "updated" they claim to be comming out with the 3:1 kit "planned release date 2005" is there hope yet? it get me excited and motivated to go 6:1-465/3:1-205/4:1-doubler/5.13 gears.. if my calculations are correct that equals a very stupid low combo:saweet:, but then again it'll prolly cost a grand for the 3:1 case and gears. :rolleyes:

    Im not sure the 3:1 gears are going to amount to much personally. They are gonna be spendy and in the end you just have a lower low range. Seems like a klune or doubler would offer a lot more options and maybe even cheaper too. Also, they have been saying they are going to come out for like 3 years now... I'll be skeptical until I actually see'em out and about..

    This is not quite correct. a stock 205 has a 2:1 low. coupled with the range box of a 203 (again 2:1), gets you 4:1. a doubler.

    By upgrading your 205 to 3:1 low range, and the 203 range box (2:1 still) you'd have a 6:1 low range.

    plus your 6:1 465 and 5.13 gearing would net you a final crawl ration of 184:1

    :D

    They are not that much more than a used 205 + rebuild. I don't find them to be a substitute for a doubler, but a nice compliment (like the WMS 203 3:1 kit). The 3:1 gives you a nice in between low range gear (a big thing with autos).

    3:1 plus 2:1 would give you 5:1...

    *EDIT*My info above is wrong and the beast was right and you woudl get 6:1. Dont know what I was thining.. Sorry!!



    Which would net you a double low range ratio of 201.61:1(with sm465 and 5.13's)....

    If you installed WMS's 3:1 203 gears AND the JB 3:1 205 gears, then you'd have 6:1. :D This would net you a 302:1 low range with an sm 465(6.55:1 first gear) and 5.13's....



    But I think by that time, I'd rather have an Atlas! The WMS gears are $1000(may include the box too), then I imagine these 3:1's for the 205 will be pricey.. With the 3:1's and a doubler set-up you get more gear choices though.

    The 3:1's with a single 205 behind an auto to be a half decent alternative to those with Auto's(or manual guys too) who want one case and a stronger t-case than the 208 and 241. But then the price issue comes into play again...

    yeah... i definitely need some more gear (700R4/205/4.56s pushing 39.5s). I am going to 5.13s but I'll need more than that. I planed on going doubler. If the 3:1s were inexpensive enough though (read, less than rebuilt case, doubler plate and shaft adjustments) I might be interested. Is there a firm price for the lomax gears yet? only thing is, Im not sure if even that will be enough gear. hmmm...

    lomax - 3.06 x 3 x 5.13 = 47.1:1 (not including tc mult)

    Doubler - 3.06 x 1.96 x 1.96 x 5.13 = 60.3:1

    what I got now - 3.06 x 1.96 x 4.56 = 27.3:1. :crazy:

    The real problem is when I'm trying to crawl over big azz rocks... I have to get the rpms up enough to get moving but then I sorta lurch forward and have to brake again... hard to control that way. With lower gears I could actually crawl like I'm supposed to. :) I guess the question is... would 94:1 be enough or would 120:1 (tc mult added in) be better...

    The D300 kit is the only one I know of. The last price "idea" from them (a year ago on PBB) was hovering around $1000. This is for a new case, gears, bearings and everything you need.

    well, $1k wouldnt be toooo bad. Its not much less than a klune tho, which offers lower gears, is clockable, has cable shifting etc etc... hmmmm...

    dont get your hopes up its been there for a while and you need to buy there new case, theres only a couple of things you reuse from you 205and w/ the price why get a klunev or something

    The last release they had on PBB said the case was included, the t-case was complete ready to bolt in. Klune doesn't reccomend the lower ranges for fullsizes.

    yea there 4.0 one are for jeeps, w/ there 2.7 one is for fullsize, IMO 4.0 would be way to high but thats also coming from an eastcoast guy were 100.1 would be a little high

    I was reading this and i think you may have made a mistake.
    Dont you multiply the two t-case low ranges together not Add them for your crawl ratio!

    So 3:1 and a 2:1 would be 6:1,
    a 3:1 and a 3:1 would be a 9:1 reduction in the two t-cases?. :confused:

    However, you did do the calculations by multiplying them so the 201:1 and 302:1 crawl ratio are correct. Just thought i'd point that out.

    3:1 gears would be nice.

    A 203/205 doubler seems kind of silly to me unless you run 4.10s with an automatic and big tires.

    A 241/205 doubler would be a good idea. It allows you to have two low ranges and a "superlow". It allows you to run airplane gears in the differentials so while traveling distances your driveshaft speeds are low and you don't have to worry about them blowing up because they aren't balanced.

    I run a 465/208 with 3.73 gears (64:1) and 40s. In 1st/low it cruises at 1.3mph at idle. Can you say nap time? I can just let it idle over most obstacles because the IAC valve will open and keep it running at the predetermined 1.3 yawn-per-mile. I'd like to run 4.88s or 5.13s for the simple fact that I would never need that unsynchronized first gear. As it is, I usually idle around in 2nd for most of my trail riding. 3rd gear I use sometimes but it's fast enough where i can't sleep while wheeling.

    I've been kind of waiting for Kyle @ NorthWest Fab to make a kit that has a new NP241 output and adapter to mate to NP205. If he played his cards right he could continue to make the "universal" adapter plates so he could run either a driver drop or passenger drop NP241 and someone could use the other front output for a PTO. If he was superslick he'd make a short 32 spline 465 output so you could run a shorter adapter and end up about as long as a 203/205 doubler.

    Why is it I never see any body but jeepers using SM420s? Every one loves the SM465 for it low 1st gear. The SM420s have a 7.0:1 1st, 3.6:1 2nd, 1.7:1 3rd, and 1:1 4th gear. Heck these things were used in ½ to 2 ton GM trucks from 1947 to 1967.
