Doing some work to my JTR MT the last 6 months, this is where it is at:
X-Bull 13.5 K winch
Chop fenders with liners
4.5" Skyjacker lift
ICON Rebound Pro wheels with Toyo 40 X 13.5 X 17 Open Country M/T tires
5.38 Dana Advan TEK ring and pinion
Molle bed panels with Motobilt Hi-Lift jack mount...
From what I understand if you are pushing your Dana 44 hard off road 40's with 10 to 13 psi would be all they would take. To go bigger would require Dana 60 swaps. But I could be wrong.
