I’ve seen them on the rebels already. The one I was getting had the factory black step bars on it. Ended up canceling because the part on the etorque was on indefinite recall. I ended up building and ordering one to my liking without etorque.
I’m a 2019 rebel owner as well in your same situation. My dealer told me mopar is waiting on approval to sell the black side steps as aftermarket accessories and they could be available as early as mid October. So I’ve decided to be patient and wait (and give my wife and kids a boost getting in in the meantime!)
I just installed running boards from Running Board Warehouse and love them. I went with the "Iconic Factory Style" and they went on super easy and fast. I'm 300 pounds and there is no deflection when I jump my ass up there.
