I am wanting to order the Rough Country 2in Leveling kit but not sure whether I have an aluminum or steel control arm? Anyone have any idea what a 2013 GMC Sierra SLE Z71 has? I would go and check myself but I work a lot and unfortunately it is roughly 5 degrees outside and I don't have a garage. Brrr.

Aluminum is not painted, its easy to tell just by looking. Its the natural color of aluminum. There is no other way to know without looking. Turn the wheel out and glance.
