Anyone have any info on how the ecoboost is responding to lift and big tires? I want to put 33's and at least a 4inch lift on my truck, just concerned that my milage might drop like a rock i dont know what they are doing when their loaded up

 

I have a 2" leveling kit (in front, nothing in the rear) and I'm running 295/60/20 (34") Nitto Trail Grapplers.I lost about 1.5 mpgs. I would guess with a 4" lift raising the truck even higher you'd probably lose a bit more mpgs.Finding lighter tires would help a little too. MyTrail Grapplers are 10 ply and weigh a ton.
Something else to consider, 33's will look pretty small with a 4" lift.

 

Damn your truck is sexy!

 

Thank You

 

Is that the factory wheels?

What front level kit did you do?

 

Yes those are the factory 20's that are optional on FX4's and FX2's.
Autospring 2" leveling kit.
