These stats are comparing the semi float dana 60, so im guessing if they were comparing the full floater dana 60 it would have much higher load carrying capablity.

a good ratio for your rear end would be 4.56 or 4.10 thisll put you back into the stock power band. with those big tires your out of your power band right now check this out (click here)
look at the third or fourth down. 4.10 or 4.56 are what you need to spin the big rubber you have on there now, 4.10 will put you about equal to the stock set up and the 4.56s will give you a slight advantage and better torque (not more torque, it wont in crease your torque, itll just let you use it!) at take off.

unfortunetly due to being in college and having a GREAT (that was sarcastic) job as a grease monkey i dont have the money to get new gears, so i still got my 3.55s out back, but that will change someday
