what trans gear, tcase gear, and rear gears do you have?

tq x trans gear (usually first) x tcasegear (usually low) x rear gear = final tq

so

277 x 2.46 x 1.96 x 3.55 = 4741

and a *massive* crawl ratio of

2.46 x 1.96 x 3.55 = 17 to 1

i think all those numbers are right for a stocker, i did it from memory, but it should be close.

*note* torque in a auto tranny in first gear is multiplied about 2x, just the way the trans works.

no, actually, in 4wd you get less power to each wheel, because the same amount of power produced by then engine is divided 4 ways. It depends on what traction devices you have as well (lockers, etc). But then again, this is all theoretical, because there will be some loss of power due to slipping and such.

At least thats how it seems it works....Im prob wrong.

I think its the other way around IMO. If you have 3.50 gears in both diffs. and shift into 4wd you would have a total ratio of 7.00, 7.46 if you had 3.73:1 ratio (just in the differentials) I figured it this way..

7.00
x 2.46
x 1.96
= 33.75

then

277
x 33.75
= 9348.75

9348.75
x .16
= 2991.6

2991.6
divided by 4
= 747.9 Per Wheel
