Post subject:  diff ratios and transfer case

i have been reading a bit about transfer cases and diff ratios and i'm a bit confused as to what the correlation is between them?

e.g. i have wt diffs in my nt sierra but i have 3.9 ratio diff centre.
i run 31's and i have the 1.6 efi swap i keep hearing people putting 6.1 transfer gears.

i can understand how this would help off roading but i'm not sure how it would effect normal on road 2wd driving.

can anyone shed some light on this for me?

It lowers your driveline by 18% (I think), which just means it makes it a bit more driveable with those big tyres.

I have a 1.3, 31s, 3,9 diffs and a 6.5 Tcase, and I can now drive up hills in 4th and some in 5th, wheras before I would struggle in 4th.

I wold also be revving out at 4500rpm trying to do 100, but now I can sit on 110 easily.
