1999 F150 5.4 4x4

So I'm going to put larger tires on my truck and get my lift on at the same time in about 90 days. I'm also going to re-gear. I'm not 100% sure on whether I want 4.10s or 4.56s (leaning towards the 4.56s). I have found some Rings and Pinions from summit racing, however Im not sure on which ones to get. I need both front and rear gears and can only find the rear. Any help is appreciated: websites, other forums, direct links, advice... The tires are more than likely going to be 35s however I may go slightly larger.

 

Not sure what engine you have but if you are thinking of going bigger than 35's go with the 4.56's.
