I have a 04 5.4 4x4 f150 with a 2" level and wondering if the stock gears would be ok or if I should change gears

 

What ratio do you have? If you don't know, post the AXLE code on the door jamb sticker or the full tag number on the axle.

 

It says 19

 

That's 3.55 non-limited slip.

No need to change them unless it feels sluggish. If you do change them, go with 4.10's and be prepared to pay about $1600, you have to do both front and rear.

Whether you change them or not, you will need a programmer to correct the speedo/odo for those 33's.

 

OK, any preference on programmer
