I have a 2006 Ford f150 that is getting a 6 inch bds lift and 35" BF Goodrich KM2's, I was looking at getting 4.56 gears so i get better gas mileage, what is this going to do to my acceleration and speed? What do you think about re gearing?

 

I think regearing is a good idea.. I've always been told thought going to taller gears will decrease your gas mileage but I am not gearing professional. Depending on which route you take, it can be very time consuming.

 

REGEAR! lol, I couldn't be happier with mine. I have the 4.56 G2 gears on mine as well, and I don't know what the hell I would do without them. My truck is much more torquey now, and pulls hills with ease. Not to mention, it saved my MPG's. I have 7.5" of lift, and I still get stock MPGs with the new gearing. Also, regearing will save your tranny from the added stress of the bigger tires
