They shouldn't be Rebel specific because Rebel just means some trim pieces.
2016 brought no major changes to the Ram 1500. Frame should be the same as 2015. So far, everything else seems to be, aside from the trim mods. The only underpinnings that are actually different from the 2015 year that I've seen or heard of so far is the pre-installed nuts in the nerf bar mounting locations. But it wouldn't hurt to ask your dealer, as they should be able to double check quickly enough. Give them a call.
