I did a six inch procomp lift and the 35's. I knew gas mileage would goto crap, but it sits at 11.


It has stock 3.55's, what would be a good gear ratio to go to?
also doesn't like to get to 6th, loves to hold in 5th.


SCT tuner, and that's it.


Thanks!

Well, I don't know if it is the same on the newer trucks, but I put 35's on my '97 F-150 and asked what ratio I should go to as I am on 3:55's as well, and people are saying either 4:10's or 4.56's, it depends if you like gas mileage or a little bit more get up and go power.

I was thinking 4.10's
But wasn't sure if that would be enough to give me a little better mpg and better performance?

I assume you noticed a bit power drop like I did when you put the 35's on, 4.10's will give you a little more power but I think worse gas mileage, and the 4..56's will give you a lot more take off power with worse gas mileage than the 4.10's. It's been a while since I looked into it because it is just too expensive for me to swap gears haha.

I would try to post a thread in the 09-14 sections at https://www.f150forum.com/f38/
