Leveling kit Questions (MPG)

Im thinking of getting a 6.7 and having a leveling kit with 35s put on. What kind of MPG are you getting with the kit put on?

I don't think that you lost 3mpg from the 2" kit, it was the Nitto's that did that, running a MT tire you can lose 2-3-mpg alone.

For the most part a level kit will not change a thing. But the tire will be the mpg killer. Using a good AT tire will help keep the mpg's.

To clarify for you, I wasn't insinuating I lost 3 mpg due to a leveling kit. He said he was wanting to add a leveling kit/ 35s. I have a leveling kit/ 35s and lost 3 mpg.

I was just clarifying to the OP that if MT tires are run it kills the MPG.

I agree that the MT's are the biggest killer. The weight, wind and rolling resistance is greater than an AT. I would get better mileage with my MT's when the tread was worn down than when they were new. I also think that the leveling kit plays a roll. The more air getting under the truck hurts it's efficiency, especially at highway speeds. There is a reason Ford put those massive air dam's on the front of these trucks.

I'm just lifting my 2011 SD now. But the last three trucks and a H2 that I leveled had no effect that I could tell. That being said I drive 25 miles each way every day and fuel stops are like clock work for me. But the time that I changed to a.more aggressive tire mpg took a dive. And yes 6"+ lift or taking the air dam off you should see a drop in mpg. This has been what I have seen. Your mileage may very.

I bought the pro comp 2.5" front leveling kit for my 2012 f250 ccsb. Had it on for 3k miles and hate it! ride is harsher then factory. rode in a truck with icons 2.5" stage 2 and it is sooo noticeably better then factory that it is definitely on my short list of things to do! I did not know anything about lifting trucks and learned the hard way that you get what you pay for!

As far as the MPG difference, I got the same as stock setup 16.2 mpg with the front leveled (it actually sits 1 1/2" higher then the rear) just ordered the rear blocks to fix this!

I ordered 20x9 fuel hostages with 35" toyos they are being installed tomorrow with the rear block kit. I will let you know how my mpg adjusts

20x9 fuel hostage with 35" toyos I drove 250 miles today reset my fuel economy before I left I got 13.8 on the way to Orlando, installed a S & B intake in orlando and drove back home reset it again and it is reading 14.9 mpg. Not sure how accurate this is as I was watching the mile markers go by slower then the odometer was changing. hope it helps!
