Personally I wouldn't waste money gearing a 35...find an 8.25 at the jy.
Or an 8.8 if you can weld.

For 33s I say go 4.10 or 4.56

Hell i just went to the local jy, pulled a 8.25 off a 4 cyl already had 4.10s in it. Only $65 lol. I dont intend on running bigger than 32s . If ya want 33x12.50 or bigger ya probably would want to grab a 8.8 with disc brakes. But whatever floats ur boat man, just my 2 cents

This can be true. I have a trailer hooked up most of the time, so a

lower gear is a must for me in the hilly area I live in. Going downward

I do save on brakes with the lower gears....

with 33's id def do 4.56. Unless you can gear them yourself its gonna cost a pretty penny so to have any thoughts of regret from not gearing low enough afterwards kinda sucks. Im bout to do 4.88's and its gonna cost 1k to have it done right

about 1.5k at the local 4x4 shop but i found an automative tech guy that can do it for less
