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've got 35s under my 02 screw and I have 3.73s. I love em. At 80 mph I'm doin just over 2k Rpms. Still get decent fuel mileage Sent from my iPhone using Tapatalk
i would honestly do 410s before 456s, but id keep reading up on forums to see how its worked for other people
