Do I need any fasteners to install this, or does it come with mounting hardware?

The step assembly is included. Confirm the pin and clip hardware that came with your receiver hitch are present and in good condition—this step uses the same mounting system. If your hitch hardware is missing or damaged, you'll need to source a replacement pin and clip set separately.

Will this step fit my 2-inch receiver if it's been used or has surface corrosion?

Yes. The receiver opening is standardized at 2 inches. If your receiver bore is clean and dry, the step will seat and mount normally. If corrosion is heavy, a quick wire brush or steel wool pass inside the receiver will ensure a tight fit.

Does the chrome need any prep or maintenance out of the box?

The chrome arrives ready to use. Rinse with water and dry after delivery to remove any shipping residue. Periodic washing with soap and water keeps the finish looking fresh—no special coating or sealant needed unless you're storing the vehicle long-term in a salt environment.
