Factory GM Step Rails

Refine Results

Many GM trucks or SUVs already have step rails installed. And if your vehicle isn't already equipped with them, chances are, they're compatible with them. Step rails are also known as side rails or running boards. Whatever you decide to call them, they provide a stepping surface for entering and exiting your vehicle.

Step rails are located inches away from sills. Depending on your preferences, you can install them lower to simplify getting in and out of your vehicle. This is advantageous, especially if you own a lifted truck or SUV. Running boards are a little different. They mount closer to the rocker panels, improving their ground clearance. When compared to step rails, running boards tend to have a wider profile.
