they say aluminum, but they make two different kinds and use the same description for both. the ones i linked are the SCM435 ones which are steel. I recommend steel over aluminum because you can put them on with an impact gun without issues. i tore up like 3 sets of aluminum ones because of how much i take on and off the wheels. I personally used these blox ones and had zero issues with them.
