I'm not sure. I bought the truck used with 9,000 miles on it back in October 2014. The dealer I bought it from thought they were factory which is wrong. I then called the original dealer who sold the truck when it was new. They pulled the build sheet & it didn't show any leather options so they had no idea either. I'm guessing the original owner had the custom leather installed after he purchased it. The black tag on the side of the seats says "All Weather". That is in the only marking on them.
