Driving a Mercedes-Benz SUV? There's a chance it came with step rails. You might also refer to them as side rails. Less often, you might even hear them called running boards. The sports car community also has their own name for them: nerf bars. The term is taken from "nerfing," meaning bumping into another racer. Despite their many names, what a step rail does is provide a better surface than a bare door sill for getting into and out of your vehicle.
If you know them already, you probably already know they mount just inches from sills, and that you can install them lower than that to make entry and exit even easier. Doing that is especially advantageous if you're driving a lifted SUV. Running boards are a little different from step rails and side rails, though. They mount closer to your vehicle's rocker panels, or flush with them. That provides better ground clearance. Running boards also often have flatter and wider profiles, and their treads often run the length of the boards.
