That air dam you want to remove probably nets you 1-2mpg gain. Removing will make the air more turbulent under the truck and cause drag, which = less fuel economy.
Funny, those who have removed them on the 2011-2014's saw no change. Had one on my Nissan, removed it and saw no change. Besides, he already lifted the truck so a lot more air passes under the truck anyway (and there is more space too).
It may serve a purpose but it certainly is not going to change your mpg's by 5-10% (which is what you are claiming by saying 1-2mpg). Minimal impact on mileage.
And don't come back with the argument that Ford's engineers would not have added if it did nothing because it could be that engineering didn't add it but some designer added it because they though it looked better. IF you want to reduce drag under a vehicle, just add a full belly pan and be done with it.
washed the truck today, and took a better photo of how the exhaust tips sit. spacers should be installed by friday so i get some photos of how much they push the wheels out as well.
also looking at a set of these up front. fox or boss coilovers. i would like to get a little more lift up front and might as well go 0-3" adjustable while im at it so i will be happy. really, another 3/4" would make me happy.
I can tell you that I have used Toytec (sister company to F150Lifts) for my Tacoma's lift, and their customer service was excellent. If I was going coilovers on an F150, I'd take a hard look at their BOSS system (if available for '15). Just my $0.02.
i had toytec products on my tundra before and i agree they have excellent products. i already spoke to them and stage3motorsports and the 2014 boss coilovers fit the 2015
how much did you lift yours with the coils and how do they ride? im very content with the factory ride and dont want clunks and squeaks if i install something aftermarket [MENTION=169964]MCDavis[/MENTION]

Most common "length" would only be about 8". However I can print you plugs all day long
