Multiply the ratio of your first gear, your lowest transfer case gear, and the ratio of your differential.

Example: 3.93:1 (first gear) x 2.57:1 (t-case low range) x 4.10:1 (differential ratio) = 35.4:1

Toss on some 33's and it does not seem like much.

Yeah, I'm at 42.2:1 and running 33s. It does okay, but I really want a Taco Supreme from Marlin. That would put me at 198.3:1.

That should be great with 37s, plus I'll be much better off on the highway.

The above formula is also basically how you calculate axle torque to figure required axle shaft strength. Just multiply by your engine's net torque and then by 0.85.

Right now I put out about 6,347 ft-lbs. With the Taco Supreme, I'd be pushing 29,800 ft-lbs and change!

I thought the Taco chain driven case was 2.57:1? Could be wrong, have to go check Marlin's site.... If my numbers are right, I'm at about 226:1. :D

Later,

Indeed they are. I will change my post.

That puts me at 49.3:1. I need a Taco Supreme!
