With all the other gearing options, I cannot see any reason why you would want to increase the overall length of the drivetrain by another 8" to add one of those....especially when you can get a Stak.
4 speed atlas basically has a klune on it already...
Klune/Atlas = $$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$
Stak is a lot cheaper.

I meant 4 speed tranny.
Anyway, I have not been following the Portal Tech stuff, but 3:1 final or is that the diffs plus reduction? There has to be some reduction in the portals IF they are really portals and not just high-center axles.
Anyway, 3:1 to 7:1 sounds to me like your choices in the 3rd member befor a 2:1 portal reduction. Clarify that then decide what you want for a final drive ratio. Then lets come up with a plan

I know of no 1.5 ish ring gear ratios so I just don't know how they can do a 3:1 final.
Anyway, back to the original question: Which case.
Lets say you stick with the SM420. I know Medusa will hate this, but to keep it simple, lets round down/up to the closest number here for ratios.
SM420-7:1 x Portal Tech-5:1 x STAK 3:1/5.5:1
That gives you 105:1 and 192:1 for your crawl ratios.
Toyota 4 speed-4:1 x Portal Tech-5:1 x STAK
60:1 and 110:1
I like the SM420 options there the best. 105:1 is a great final drive for crawling and use of 2nd gear to get the wheels spinning.
192:1 is sick, sick, sick and will be a fun ratio to have when you want to play with it.
I vote to keep the SM420 and get the STAK in the current ratio they are offering.

And if I keep the Ranger OD (83:1 & 152:1) I also could cruise HW at a decent clip without over-reving the v8 ... road trip!
Anyway, if 192:1 is so sick
and loosing it is goodthen why not go to a 4.5:1 (75:1, 95:1, 135:1 & 172:1) or 4:1 (66:1, 84:1, 120:1 & 153:1) final ratio?Mace said:
I'll need ear plugs for all the gear noise and a map and guide to all those levers

ah, I understand.Mace said:
Well working it backwards, 55 and 70, with 35'' rubber, OD and 4.88:1 final would be between 2 and 2.5 K rpm, with 4.5:1 it would be 1.8 to 2.3k, hmmmMace said:
I've never driven an FJ with a big V8, so is that high?
Just out of curiousity how many of you guys talking about the stak box have actually installed one? They are freakin huge compared to a Atlas or an Orion. HAs anyone dealt with tranny tunnel issues or are we just settling for a bunch of crap hanging below the frame rails.?
Well aware that the STAK box is larger than an Atlas or an Orion....buddy is installing one in his buggy...
I had to modify the floor/tunnel of my Red truck when I installed my Atlas, so that I had flat bottom, because I was sick of the stock Land Cruiser case hanging low...and I am running a three inch body lift.....
Other than an Orion, there is no getting around this bud....no matter Atlas or STAK....
Good luck!
