How do these twined transfer cases work? I got a couple of BW 205's and i want to make good use of them in a upcoming project involving highly a modified Twin Traction Beam set-up.
well. as for anything TTB, i wouldnt go that direction. as for how a twin stick works it allows you to be in 2hi 2lo neutral 4hi or 4lo as opposed to 2hi 4hi neutral and 4lo, you basically gain a 2lo setting. with 205s there are plaenty of kits out there to do this conversion very easily, you may also look into a doubler kit, that was you are able to run 2 xcases to gain extremely low range gearing.
So let me get this straight, you can get front high ad front low, along with rear high and rear low, and the standard 4x4 high and low right? Now how would one go about doing a job like this? Also if one is to use a doubler kit would i be able to get the front hi and front low, rear high and rear low to?
I have yet to have bad luck with the TTB, and from how bad me and my dad beat on some of our truck with the ttb, i got my reason for using it, and it won't be staying a dana 44 though.
Doubling cases involves taking the gear driven portion from an NP203 and mounting it to a 205 using an adapter plate ($500-$1000 depending on where you buy the kit). What this does is allows a lower gear ratio. 205's low gear is around 1.98 to 1 so if you add the 203 gear set you can cut it in half again, basically to around a 4 to 1 ratio. Twin sticking involves some minor modifications to your shift rail and, of course, adding a second stick. It's easy to do and can be used with or without a doubler setup.

A doubler will only be necessary if you're doing a lot of crawling or something that requires a ton of torque. It all depends on what you're using your truck for. Either way they're damn sure cool!
Cool thanks for the info. I now know how the doubler works and with that article(i think that i have that mag that that asticle is in to) and your description i will be able to do a twin stick conversion.
I have an idea here now that i think about it. Could one modify a transfer case to work in a 2x4 to give the 2x4 a low range for something like drag racing? If you could get rid of all of the extra gears and chains (i would use a NP 203) and modify the linkage like a twin stick you would have a low range for the street for drag racing without losing the milage of have 5:1 gears. (i also cut the case and make a cover to get rid of the unneeded bulk.) Would this be possible?
Just run a transfer case with no front drive shaft in 4 lo, then you have 2lo, I do this all the time, but I don't take the drive shaft off, I just don't lock in the hubs.
Hmm, seems like a lot of work and unpredictability to me. You can definitely use a transfer case in a 2wd to give you a low gear. I don't know that this would do much good for drag racing though, unless your engine can handle insanely high RPMs. Mine wraps out at about 40MPH (scary!!!) in 2wd low . . . yes, I use it around town to do burnouts. If you're looking at racing I would just regear the rearend. If you've only got a 2wd you wouldn't need to bother with a twin stick conversion, just use regular 4-lo and save the hassle, as you won't have anything connected to the front shaft. I'm thinking it will be very risky to start cutting the case to eliminate weight.
Is your truck 2wd or 4wd? What exactly do you plan to use it for?
Originally posted by 85351ho what if you want 2 wheel low rear when your hubs are already locke din and you dont wanan get out?
I usually always unlock mine after I'm done 4 wheelin b/c something clicks in my front axle when I leave them in. Otherwise it's looks like I'm outta luck, but he's talkin about puttin one in a 2wd, so it's more of a personal problem for me.
