Here is my 1996 GMT400 Suburban's torque to the drive axles:
7.4L's torque 410 ft/lbs at 1,800 RPM x 2.48 1st gear x 2.72 transfer case x 4.1 diff
410 x 2.48 = 1,016.8 ft/lbs at the tranny output shaft
1,016 x 2.72 = 2,765.7 ft/lbs at the transfer case output shafts
2,765.7 x 4.1 = 11,339.4 ft/lbs at the diff output shafts (front and rear)
4L80E ratios, 1st to 4th (OD)
2.48 1.48 1.00 0.75 2.07
NP241 transfer case ratio
2.72
Diff ratio (both front and rear)
4.1
Enough to break things in a hurry if I put my foot into the throttle
pedal, but I'll not do so because of my decades off roading...seening
folks break things out there in the boonies...heck even out at Pismo
with loosey-goosey sand...
In 2wd you might not get there without the fronts clawing/pulling along
with the rear...so might give it a bit more throttle...to break
something back there...
With today's much higher torques...MUCH MORE EASILY break things and
even faster than ever before...hoping the vehicle computers know that
it is in 4x4 LOW....
Home now and not using an Ipad...so can post better pic's...and laughable
when folks say they will 'watch it'...this and other stuff happens
in a flash...
