Is any one using the Black Box from North West Fab? Ive searched but not found anyone using it....assuming they have it available for a toyota that is.

Looks expensive, $1600 and I don't see a toyota application. But it would be cool, go for it.

lol yeah the price is one thing thats bothering me about it. But it seems real simple, which is cool. Are their other brands out there that have the same thing? Its basically a double tc, without being a double tc, right?

I'd be cheaper to go dual cases. Plus it's longer than an addition case...IIRC.

Looks like it's geared (get it ) more to the GM guys HOWEVER the site claims a "wide range" of applications....

Drop a set of 4.7's in your tcase for a fraction of the cost....

Humor me please. Is the marlin "dual case unit", for $630, the same thing as that black box basically? From reading it, I tell myself that it bolts on and keeps it a single case application, but with dual sticks...is this way off?

Basically. Both the blackbox and crawlbox go between the tranny and original tcase. You will have TWO reduction boxes either way. I'm not sure how the "shifter" works on the blackbox, perhaps a cable. Dual cases there will be another shifter. That means TWO crawlbox shifters. One for reduction and one for reduction AND 4WD. "Twin sticks" (or what I am confusing with "Dual sticks") is commonly refered to as when you split the shift rails up in the crawlbox to make 2WD/4WD and 4hi/4lo move independantly instead of the typical "J" pattern. In that case (get it ) you would actually have three tcase shifters....

Ok I think I got it. So with the crawl box, you have two shifter, stock tc shifter and the crawl box shifter, so if I went with the 2.28 crawl box, it would be twice as low as stock when both are in low correct? About the same as just doing 4.7's in my stock case?
What is this setup called? All I remember ever reading is dual cases, dual trans or single case reduced. Is it not a popular route?

The nice thing about having two reduction boxes is the ability to retain the original 2.28:1.

Essensially yes, 2.28:1 x 2.28:1 = 5.1ish:1 reduction or you can go and modify your current reduction box to house the 4.7:1 gearset(which, btw, is REALLY simple to do at the fraction of cost of adding the second box. You'll have to have a custom crossmember, driveshafts...etc).

I currently run a 4.7 in my singe reduction box. I love it. Only one tcase shifter. Eventually I may twin stick it.

I don't not believe there's a clever name for a single 4.7 case.

The argument one might get for having a single case with a 4.7 setup is speed on the trail. Not all trails require such a reduction to run, which is why it's nice to have that 2.28 option. However, with a manual tranny, you still have 5 forward gears in low range...so instead of running low range with tranny gears 1st and 2nd you can run tranny gears 2nd and 3rd or even 3rd and 4th

Thanks for the help, it can be confusing. I'll prolly do the single 4.7 since its the cheapest route. $500 is about the going price everywhere isnt it forth the gears?

Yeah roughly, TG usually has deals every once in a while for cheaper...
