Has anyone replaced their 3.73 ratio with 4.10's. If so, do you like it? Very much diffrence?

I take it you want it to be more sled friendly? IDK, the higher geared the better IMHO.

Not sure what your goal is but 4.10's would allow one to run 5th LO range better. I turn 4500rpm and let it rip in 4th LO and it runs like a scalded ape. I've tryed 5th a couple times and sometimes it works and sometimes it don't.


On another side of it my 03 dually is a turn and with 4.10 gears maybe it'd run better but IDK.
