Rear end selection help and opinions

Well it was close enough for the factory to use 3.55 in the read and 3.54 in the front on the Dana 44 in 4x4 Dodge trucks. I just wanted to make sure you knew there was a difference so you would get the right gears for the right differential.

That's common in 4x4 trucks so the front moves a tad faster that the rear. My F-150 is 4.11 and 4.10.
