Whatever the tag says is what you have. NO WAY would there be changing of gearsets on the assembly line.



That's what I would've guessed, but wanted to ask anyways. The axle says "P68214859AA 3.21" on the tube. The truck's window sticker and VIN decoder both say 3.55 axle. If the ratio is wrong, now I'm curious if they included my anti-spin or not.
