thanks guys hopin the new engine works well would like to know if anybody has an idea on how much hp and torque it'll make. oh and the winch gets used more often than you think, When it's that big you tend to try things other won't and when it's stuck man is it stuck.:D

That aint a monster Bronco, thats a mega bronco, what size winch do you have it got to be a beast to get out, how many trees have you uprooted when it was stuck

the winch is a 20,000lb hydraulic ramsey and it'll drag about anything out or drag whatever is hooked to it in with ya too.

How do you have a NP205 feeding into a rockwell transfer case? so do you have a compound low gearing?

awesome rig... and I thought 6 inch lift and 38s on my bronc is gunna be sweet... yours is insane!

also... why 5 ton and not 2.5 ton axles? did you really think you needed the extra beef? or just the wow factor?

with the 2 t cases I get 4:1 lowrange with the 6.44's it gives me a final around 24:1 which works perfect for the tire size. As for the 5 tons well I'll put it this way I broke over 20 2.5 ton shafts in about a year and a half with smaller tires (57") and it was either spend 4500 bucks on overson shafts for them or I bought the 5tons at scrap price and the are overall stronger and I haven't broke any axle parts since. It gained about 1400 lbs more with the 5 tons and bigger tires than before but as for driving it you can't tell the diff. it's just a little heavier to haul around (10,000lbs) but I pull it with a 93 F350 crewcab with a 460 hopped up with a crane cam and doug thorley tri y's and it'll smoke the tires off at a redlight with the loaded trailer.:D

No the blue truck is my buddy Rob. His crewcab is a bit bigger than Dales truck. it's on 65" tires also.

How do you mount and connect the two cases? and with such a short wheelbase? im assuming they are connected via a short driveshaft between the two cases (unlike a 203/205 doubler) you have any pics of that setup? and shift linkage etc... and does the 5 ton case have the typical 2 hi, 4 hi, 4 low selections?
