soo the low gear in my truck isnt low enough  thats a 1.82 to1   the t case in low is 1.94 to 1   and 6.71 to 1 on the axels  i think anyway  with a 54 inch tire  whats the finnal ratio between the trans t case and gear         also whats the 1st gear ratio between a 400th verse 350th   i can change out the trans low gear to a 1.76 to 1 pretty easy and have the parts to do it but dont know how much ill gain      or there are aftermarket gears i could get for it     but  unshure of what way to go

Put another tcase in it and double up

check out this site, you can select your trans, t case and put in what axle ratio you have and size tires and it will tell you the final drive ratio, mess around with it and you can figure out what final drive ratio you want :)

thats what I got too and if you do the above mentioned as doubling t-cases it will put you around a 45.1 ratio..... you could get a 4:1 box and that would put you at just over 92:1 ratio
