double transfer case... two speed rear end

Its quite obvious that the gearing on the m715 is very tall... and this can be compensated for with taller tires, and an overdrive transmission.... Has anyone installed a second transfer case in order to act as a 2 speed rear end? The arrangement would be as

Engine-Tranny- trans case 1 (with front drive shaft going forward to front axle/rear drive going to next transfer case which would control the high/low range) - differential....


Obviously you couldnt run 4wd with the second transfer case not with 1:1... Any write-ups from 4wd discussions etc would be great... most things ive found are so you can go with ridic crawler setup and large tires... I would want tor etain the normal driving of the current 4.89/5.68, and then be able to have a highway range... especially with a diesel conversion in the works (lack of high RPM availability).

Thanks,

post pics/decriptions if you have them

There is something at advanced adapters called a Range Torque Splitter that goes between the engine and transmission that acts as an under or over drive (one or the other, not both) that gives a 27% overdrive or a 17% underdrive. You could mount an overdrive and keep the rest of the drive-train so you could keep the trail performance, and the four wheel drive, but get some highway ability to.
