"The Optimus Side Steps were designed by Vanguard Off-Road to have a premium, rugged look, while also having a structurally robust build. They are made out of Q235 Structural Steel and have an electrophoretic black primer, combined with a black powder topcoat. These steps have a 5"" wide step area and are capable of supporting up to 300 lbs. They also have an open-channel design that allows wet elements to drain from the surface, so you can maintain your traction even during inclement weather. Trimming of the undercarriage plastic cover is required for most applications during installation, but all the assembly and mounting hardware needed to install the Optimus Side Steps to your vehicle will be included. All Optimus Side Steps are backed by the manufacturer with a limited 1-year warranty. So, if you are looking for a set of steps that are rugged but heavy-duty, the Optimus Side Steps are the right choice for you. | Vanguard Optimus Side Steps VGSSB-2060-1911BK"
