For a f150 with a 302 4x4 with 35 mud king tires

 

Ehats your axle code on the door sticker?

 

see this chart. You'll possibly want more if you are really going off road

Man. That just made me more confused. I was thinking 4.10's for 36's but now im thinking 4.30's or 4.56's. I dont want my fuel mileage to take a dump though

 

there are a few other charts online that are similar, but I'm no engineer so I don't know how much to faith to place in that chart for regular street/highway driving. for me it will be cheaper to switch to 32's when the time comes, rather than changing gears.

 

I have 3.31's... don't like them.

 

4.10's

 

4.10's for 35's or 36's?

 

not tryin to gack you thread here but how much more mpgs will i get with 3:31 vs rhw 3:73 i have. also they are stock tires

 

Either or. The truck will be much peppier.
