Yes, thats why I emphasize the power and potential or breaking stuff. You must be purposeful and desciplined.
The only question I have with the gear multiplying and power is the truck has diferential gears which in my case are 4.10. If I were to dyno at the wheels, Id get 300 tq for the sake of ease.
Only the transfercases would be multiplying at that point (high being 1 to 1). In my case of duals 1.96x 2.6. Although on a dyno you pull in the gear that is one to one (4th NV4500) so does that mean you mulitply torque times transfer case gears or torque times final gear ration diffs included.
Lee to answer your other question, I have not used 119 for anything other than stumps. It is a selling point. If I am forced to sell my rig, it is a cool factor some kid will pay extra for

. To answer your other question, stock 4x4s come with final crawls of 35-45 to 1 (in general). Most that add bigger tires regear to get them in the 60-75 to 1 range. This is most I read about in Petersons, 4 Wheel and Ofroad, friends, rigs I read about. That seems to be more than suffecient or most.
