with the 5.4, ive heard some people regear and are fine, others swear that you have to regear. I didnt have to worry about it since my truck is a 7700 and it came with 4:10's.

I would re-gear. I have 33's on my 4.6 f150 and I went from 3.55's to 4.30's. World of difference. The transmission doesn't keep downshifting every time you accelerate on the freeway. 4.56's with 35's is a good combo since you have the 4.6 you need to make up for the lack of torque. It will def save your tranny. Also might want to invest in an aftermarket trans cooler to keep the trans from getting too hot.
