I have a 1994 F-150 4x4 with the 302 V8. I ordered a small lift kit in the mail (3 inches) and I plan on getting larger tires shortly after, (33-35inches) I'm trying to keep this as cheap as I can, but I am reading about having to re-gear the axles after adding bigger tires. I read about Ford's a axle codes, mine is 19 which means no limited slip differential, and the gear number is 3.55, I don't know what the number means though, is it a higher gear the lower the number? My question is, would I be ok without the re-gear?

I have 33s with 3.55 ls. And it seams perfect to me

with 3.55s you can do 33s fine, unless you got alot of steep hills or haul/pull alot. if you got 35" tires id suggest 4.10s.

Why stop at 4.10?

because everyone seems to care about MPG in a truck lol. id love 4.56s in my 250 with 33s

im running 33's on 3.55's and have no problem maxing my speedometer or towing. you can just kiss mpgs goodbye especially with mud tires

Ok, thanks guys! How bad is the mileage in all of your experience?

my f150 with stock tires and 3.55s got 15-19, so i guess thats a base number.

with 33s and 3.55s id imagine a 2-3 mpg drop across the board.

i havent calculated yet but im thinking around 12 for me

Ok, that's not as bad as I would have thought, how slow will I be? I know the taller gearing will hurt my low end torque at the wheels
