They are not matched, if that's what you are asking about.
I went with the aftermarket Bosch 4-hole and they've been fine. Can't say they are any better than Mopar but certainly cheaper. Just because you buy from a dealer doesn't always equate to better quality. My recent dealer purchase was a $35 dollar pinion seal with a $7.00 National seal inside the plastic. And there was stock across the street at a jobber shop (I have a log-in so it's easy to check these things).
