Suburban LTZ 2012 with non-removable factory steps. These things are great. No drilling for easy and quick installation. I didn't remove the wheels, which didn't affect the installation. To make tightening the "internal" fasteners easier, simply rotate the handlebars for better access. The pads are made of high quality and durable plastic. They're not big, but they're not small either. I like to think my car looks "cool" and those accents are good. I haven't tested their overall goal, which is to keep road grime and debris off my lower front doors and running boards. If they work half as well as they look, then they're perfect for me.
