    noob question and i looked but didnt really see what im asking.
    wheeling this weekend i found that my reduction sucks. im not to shure of my axle ratio but im at 3200rpm at 75mph and in 1st low doin about 14mphish.

    i have th350 and 205, is there a way to add in a reduction or change the low in the xfer case? (without another xfer case) is this common? or am i a bit off.

    i seen northwest fab had something a few months ago they were working on with the front of np 241? is that an option?

    excuse my ignorance :o

    I totally forgot about this.

    Using this calculator here

    I used 4.10 and it calculated 2952 at 75 which is close to what you stated. There was something on here about a 3:1 kit for the 205 but it is like 1000. For that money you could by ORDs doubler and a 203.

    Oh he has 35s if anyone else wants to take a stab at it.

    Swap in a SM465. My final crawl ratio is 64 to 1 with a 465 NP208 and 3.73's :D Don't know if that is with 35" tires :doah: All of my friends with auto's in there K5's love my crawl capabilities from a pretty much stock setup. Just an idea since you don't want a doubler. Swap a 241 and a 465 in :D

    I say keep the auto and find a 208 or 241.... That will take your low range ratio from 1.96 to 2.61 or 2.72.

    I prefer autos though... :D

    I've got the same problem. The 205's only got a 2:1 low and the Th350's 1st gear is pretty tall as well. I've got 4:10's, 38's, Th400 and 205 and I have 0 engine braking on steep trail hills.

    I'm planning on a doubler myself. 3 sticks are better than 1 :D

    If that is the case I have a 208 I will trade you straight across :haha: . Another thing I forgot is not only do I have a deeper T-case I also have a 700R4 so my first gear is 3.16 where yours is like 2.6 or something like that. You got the green light to spend some cash on the ride get the doubler and a 203 from the JY and rebuild it. I will help you out and remember do not forget to take the gear off of the 203 shaft and put it on the doubler shaft like someone on here :whistle: .

    Was this in response to my reply? I am not following you.

    Oh and the 700r4 first gear is 3.06 not 3.16.

    It was in response to your reply but it was directed at Roz. We wheel together he has 205 I want a 205. I have a 208 that I dont like because it is slip yoke only. Sorry for confusion. I realized i was off by .1 when I went back to the link.

    No prob. :thumb: Just wondering. :D

    If you find a Dodge 208, they come factory with a fixed yoke and the parts are interchangable. So I've read. Or find a 241.

    I was thinking about that then I have to get new drivelines. I have plans for a doubler and I would like to get everything together and get drivelines made once.
