Genuine GM Step Rails

Driving a truck or an SUV? There's a good chance it came from the GM factory with step rails. You might also call them side rails. Less often, you might even hear them referred to as running boards. Even the sports car community has their own naming conventions. They call them nerf bars, a term taken from "nerfing," which means bumping into another racer. Many names notwithstanding, what step rails do is provide better surfaces than bare door sills for getting into and out of your vehicle.

Update your SUV or Pickup with Genuine GM Step Rails

If you know the real deal, you probably already know how they mount: just inches from a door sill. Install them lower than that, and entry and exit get even easier. Doing that is especially helpful if you're driving a lifted vehicle. Running boards are slightly different. They mount closer to your ride's rocker panels, if not flush with them. That gives any vehicle even better ground clearance than step rails do. Running boards also usually have flatter and wider profiles, and their treads usually run the length of the boards. Whatever kind you need for your replacement or upgrade project, we've got the best solutions: genuine step rails straight from your OEM.
