I am new here, but used to be a new car manager for Chysler during the 2nd Gen models. They have never had rail covers from the factory. Mopar did have, at one time, some Mopar parts but they used the 3M tape as well. I had some on my old truck (forgot the brand) that used 3M and they held up great. As long as the surface is clean and free of wax when you install them, you should not have any problems.
