I've been trying to come up with a way to get a good crawl ratio while maintaining some decent highway RPM's. What if I got rid of the NP200 and behind the T98 I put some 4 speed tranny with a married TC?
If I regeared to 3.55's (the highest my Dana 70 will go), the crawl ratio could be crazy (6.4 x 6 x 2 x 3.55 = 272!! ). That would give me 2095RPMs at 65mph, which would be optimum for my Olds 455. I have the wheelbase, and access to a machine shop (I'm a mechanical engineer )...
What do you think?? This is a M715, by the way

Why don't you just run two T-Cases?

I'm going to be running an AMC V8, Ford NP435, Ford NP203/205 combo in my stretched CJ-6.

Check 'em out.

I agree with Indy...run dual t-case...I am going to be running a 4.3L Th350 GM203-Ford205 so I can easily run my RC60 upfront...plus I have heard there will soon be a 3:1 gearset for the 205 available...so in just T-case you could get(if you wanted silly low) 9:1 by using both 3:1 gearsets...I will be going with 3:1 in one and keeping the other stock 2:1...so I will have options...1:1, 2:1, 3:1, 6:1 lets see an atlas do that

It's been done and I think they were mated 465's. Search and you should find it.

why don't you just slap on some 52" Michelins.
I mean really, it IS an M715...

if God had intended it to have small tires, he wouldn't made Mr Kaiser put flares on it the size of a road culvert.

These guys have done it

I couldn't find anything on their website, but I seem to remember Chris posting pictures of dual T-19s or SM465-T19 or something similar. Anyway, drop him a line.

Search is your friend, use it:flipoff2:

dual married 465's from general tech section

Great link!!

Another vote for going with a duel T-case, but have you really thought about a under drive unit?

I'd say go for it, stacked t-cases are getting old anyway :flipoff2:

Let's see something new. besides a M175's about as close to a tractor as you can get in a jeep, might as well have 32 forward ratios too.
