    I have an 04 f150 with a 6" suspension lift. I got some 37's for under it right now I only have stock 3.55 gears. Would I be ok to go with 4.56 gears? I found a really good deal on them. Has anyone used 4.56 gears with 37's? Would love to hear from them. To see the overall performance, rpm, and mph. Thanks in advance

    I've never messed with it, but heard several people going with the 4.56 gears with bigger tires and a lift and liking it. So its worth the shot. You can always go back down to the 3.55 gears if you end up not liking it.

    I got some 4.88's for the front and back to put on. Should increase the performance I'm hoping.

    4.88's will be good with the heavier rubber
