double transfer case... two speed rear end

[hcaz095]

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,

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.
