    Hey.

    I have heard of and read articles about a twin stick setup on an NP205 to give separate control of the front and rear drivelines, like allowing RWD LO, FWD LO, etc in addition to 4WD. After looking at the NP205, I can see how this works.

    But can this be done to an NP208?

    Thanks!

    ORD has a twin stick shifter for their doubler kit, maybe it will work just for the 205, but I have seen others with a twin stick 205..

    Re: Twin Stick NP208

    Hmmmmm, yeah I knew about the "Doubler"... Two transfer cases, two shifters... But I wasn't aware the 205 (or 208 for that matter) had seperate front & rear shift rails/rods like the the D300, etc...

    Re: Twin Stick NP208

    If you look at the 205 shifter assembly you can see there are 2 shifter plungers almost side by each. One controls low range/high range and the other controls 2WD/4WD. If you can make a bracket to hold 2 shifters you would have independant control of these functions.[​IMG]
    I don't know if this is so easy to accomplish with a 208 though.

  7. Nope on the NP208 !

    The NP205 has two shift rails, one is the range shift rail and the other is 4-wheel shift rail. This will allow you to set-up two/twin shifter and have more control over your transfer. The NP208 has a "mode fork" and "range fork" on the same "shifter fork shaft" within its case that is shifted with the range sector. There is no way to twin stick a NP208 from what I see inside of one.

    Re: Twin Stick NP208

    BigBurban, I read an article about a twin stick for an NP205 in either Fourwheeler or 4x4 & OffRoad magazine. I'll look it up tonite when I get home and let you know what magazine and what issue.

    Re: Twin Stick NP208

    I've got that in my save pile, too. They used a Dana 300 shifter. Curie Ent. makes them and 4WPH sells them. Avalance Eng.(the Sniper people) used to make one for Chevy NP205s, but last I heard they stopped production. Too busy making Snipers, I guess. If no one else finds the issue I'll dig it out.

    Re: Twin Stick NP208

    MAN! I'm going to have to throw a 205 in the 'Burb... It'd be TOO nice on tight trails to disengage the rear axle, step on the e-brake and let the front end drag me around a corner that'd otherwise take a 10 point turn to complete... [​IMG] I'm doin' it!!! If someone could dig it out and scan it for me, that'd be AWESOME! Thanks!!!

    Re: Twin Stick NP208

    If one shift rail controls hi/lo and the other controls 2wd/4wd only, then there is no way to disconnect the rear axle and drive only on the fronts w/o removing the rear driveshaft. Someone please clarify this cause it does not make sense to me. If its in 4wd (both axles have power) if its in 2wd (only the rear axle has power), so where is it that you can run only on the front axle for tight turns???

    Re: Twin Stick NP208

    I think the twin-stick setup allows the use of 2wd Low. What the purpose of that is, I don't know. Of course, I'm not a rockcrawler or hardcore 4wheeler, so maybe I'm just stupid... Anyway, Waxer, I agree with you about the front-drive thing. The above-mentioned stupidity clause applies here, too.

    Dude, what the hell is a twin stick for a 205 good for then? [​IMG] Just to use 2Lo?... Oh JOY! Guess I got giddy and skimmed that post a little too quick. This sucks.

    Re: Twin Stick NP208

    The twin stick WILL give you 2wd Low, which it doesnt have with the stock shifter. 2wd low is needed for rockcrawling among many other things so that you can disconnect the front axle to make a tight turn (which is needed if you have a locker up front) Cause turning with a front locker would be a bitch while up on top of some boulders. Unless you could disconnect the front axle and remain in Low gear to allow turning while slowly crawling.

    Re: Twin Stick NP208

    When you convert the 205 to twin stick you get
    rear wheel high, rear wheel neutral, rear wheel low on one stick
    and on the other stick you get
    front wheel high, front wheel neutral, front wheel low

    This was shown in 4 wheel and off road August 2000, page 118-119
    Here is a scan of the article

    Re: Twin Stick NP208

    Well thanks for the link, I just put it in favorites (and on my todo list)[​IMG]

    Just putting a twin stick set-up on the 205 will not get you the front drive only option though. As the article states you must modify the transfer case. I think this mod will put to an end the argument over whether the NP203 or NP205 is better! NP 205 is definitely the king of T-cases![​IMG] (of course I'm biased [​IMG])

    Re: Twin Stick NP208

    If you want to pay for it, you can get true twin stick (front only, rear only, or both, with hi or low range) and a 4:1 ratio! Try the Advance Adapters Atlas II case. Trouble is the $2000 price tag.
