Question About a Lift Kit
Hey guys its almost tax season time and that means truck parts for us fellas living the single life. I do have one concern and I know MPG and Lift dont go together in the same sentence. I also know this has probably been beat to death already. I drive about 300 miles a week, sometimes more. It's pretty much mixed driving. My truck is a 2005 fx4 supercab (5.4, 3.73ls, and a flareside bed), right now it has nothing but a si/do exhaust, a drop in air filter, and 265's. As my truck sits now I'm only getting 13mpg on an average week. How much is it going to go down from going to a 6" lift and 315's? or should I try 305's maybe? If I could stay at 11+ I could justify doing it. I'm just weary of me already being at 13 with 265's and going to 315's I would drop to like 8 or 9. I'm considering a gryphon and e fans as well as custom tunes though so that may help..
What do you guys think? How is everyone getting the same mileage I am on 315's and im on 265's? lol. and how goofy would a 6" lift with 305's look? Pics anyone?!

just an estimate, but if your averaging 13 now, after a 6'' and 315's i would think it about 10mpg average. i seemed to pick up 4 or 5 mpg when i switched my stock size tires on for a few days

I keep wanting to know the same thing! I do live in West Virginia so we do have some hills here and there but I consider my driving to be pretty conservative. I'm going to get my plugs changed (107k miles) and a gryphon and see if that helps any.. I could probably live with 10mpg though.. I figured it up and I can do the E-fans for about $200 so I may do it eventually too.

I have a lift, efans and 315 tires, duals, headers, cams, supercharger and 4.56 gears and get about 11-12 in warm weather. The gears really helped put the power band back. With 3.73 gears yours is going to struggle pulling those tires with a lift. You will lose 2-3 MPG I think.

I currently have a 6" and 35's and when i just checked my mileage I was getting right around 10.9 mpg Now also keep in mind I have not done gears on this. so I am running around trying to push these big ol tires on less than a factory gear. I will be stepping my gears up very soon in which case I am hoping to gain back some economy. I will also be doing the granatelli coils that are suppose to help with economy so here pretty soon I should have some feedback for you. As a side note i am getting 10.9 mpg and I drive like a jerk so I am a little heavy on the skinny pedal if you know what I mean

Have you taken into account your mpg calc may be off because of your tire size 1-2 mpg... So you really may be getting better than you think....get a phone app that will give you gps based speedo and miles travelled to compare....

Chriss let me know about those coils. I need to change my plugs and when I have that done I'm going to do my coils too.
Also about how much does a gear change from a reputable shop run you?
07_F150 - I hadn't really considered that because I figured that I was running the stock tire size so it should not be off any..
I'm going to order a gryphon and change my plugs and maybe the coils here in a few weeks and see how that all goes and what my mpg ends up being then..

I am actually in the process of putting together some gear packages. IE. Gears front and rear as well as install kits. I should hopefully be able to post those soon. As far as the coils go working on that one. I will certainly try to keep you updated on that as it comes

I have a 6in lift with 35x12.50R20 with the 5.4L and 3.73 gears and on average I get high 13 to low 14mpg which is about 20 miles highway and 10 miles city every day. when I'm actually nice to it I usually get 16mpg on the same route. I also have a SI/DO muffler, volant CAI, and a gryphon programmer.
