Hey Guys,

I have a 3.55 gear set but jumped to 35s and wish I had a truck with the 3.92 gears. There is a guy local to here that rebuilds rear diffs and has one with a 3.92 ratio and I was debating swapping mine out for that. Whats involved with this, do you also have to change the front gears when you change the rear?
I've read different things.

thx
