Hello. I just got a 7.5" fabtech lift on my F-150 screw. And after the first week I can tell that I get a lot worser gas milage. What is there to add to my truck to get better gas milage? Thanks
Mike

 

What size tires did you install? You probably need to go to a lower ring and pinion gear to get back to you OEM final drive ratio.

 

did you correct your speedo? if not then you dont really know what type of milage you are getting, but yes like wandell said you changed your final drive ratio and your truck has to work harder to build up speed causing your MPG to drop, changing out your ring and pinion (gears) to correct your final drive ratio to get the best overall performance and milage that your tranny was designed for, if you tell me your tire size i could give you the ring and pinion ratio to get you back to stock RPM, good luck
