Upgraded gears
Since most truck owners are installing either suspension or body lifts to fit larger tires. How many people spend the extra to install larger gears? My 2005 150 has 6inch suspension and 3inch body and uses 35s. I blew diff cover and was told to install larger gears. I went up to 4.88 & 9.75 diff. Can tell you that the acceleration is back and sure drives better.

Really just depends on what gearing you already have, how big of a tire you run, and what you use the truck for.
If you just go up to 33's and don't tow/haul much, you can get away with 3.73 gears but 4.10's would be better. With 35's, 4.10's could get you by, but a 4.56 would be beneficial if you tow/haul a lot.

How did the 5.4 respond to the 4.88? Any difference in mpg or performance.

Probably takes off like a bat outta hell, but im sure it drinks fuel like hell. Sounds like with only 35's and running 4.88 your final drive is like 4.65. I ran 35's with 3.73 and couldnt tell a huge diffrence but im running a programmer and a intake so maybe that compensated for it

My truck has a Edge programmer set on level 2 and use a single 3 inch exhaust. You are correct that my truck accelerates like crazy. During this winter I out accelerated another 2006 F150 on 35s with the 5.4 with stock gears. I even had my 900lbs plow and 500lbs of salt in the bed. Gears are the greatest upgrade I believe I have done to truck.

I am lucky that fuel is cheaper here and my business writes off plenty of it. It was cheaper for me to upgrade larger to not blow gears or diff again and tax my smaller V8. Plus anyone willing to add a lift for larger tires should do it properly and also do the gears. My opinion but my truck speaks volumes on how larger gears improves a stock truck greatly .
