On the way now

 

Take new tire size and divide by old. The multiply current gear ratio. So if you had 32s stock go, 37÷32=x then X×3.55. That will give you what u need

 

Here's the pic

 

That looks awesome!!! Did they have to cut the crush bar?? How was the ride with your gears?? I have 3.31 and would like to install 35 inch tires on mine.

 

It rode very good I couldn't really tell a difference then stock. It still had plenty enough power to get up and go if I need it.

 

I don't know what motor you have, but I have a 2015 5.0 crew fx4 with 6 inch lift and 35s with 3.31 gears and the truck is not bad if you drive it under 55 mph. It will shift in and out of 5-6 gears pretty quick, definitely do not tow anything and expect to drive 60-65mph. It is definitely a pig, I will be re gearing my truck as soon as 4.10s are available. They aren't available for the new 8.8 HD rear end ford put in new body trucks, but as soon as they are I will be doing them.


BTW original poster.. your truck looks nice.

 

That's good. Once again truck looks awesome

 

Thanks for the info

 

How's your gas mileage after few days of driving?

 

I swear it hasn't changed according to the computer. I'm
Gonna hand calculate next time. I am running a canned tune tho so that might be helping. It's at 14.2 MPG right now
