Running boards and nerf bars are exterior accessories that make it easier to get in and out of your vehicle. Though they both do the same job, there are slight differences between them.

Running boards, for example, also get called step rails, side steps, and side rails. They have relatively flat, wide profiles, and their treads often span the length of the boards. Moreover, they install along the sides of your vehicle's body, near its rocker panels; this setup enhances their ground clearance. Some are electric, retracting to hide away when not in use, while others are illuminated, both to help you visualize where to step in the dark and to add a unique, eye-catching look.

Nerf bars, on the other hand, are named with reference to the sports car community. The term is derived from the term "nerfing," which means bumping into another racer. These steps are more tubular (tube-shaped) than flat, and they typically install under each door, offering a stepping surface that's a little narrower than a running board.

Both are viable options if you're looking to add a step to your vehicle. It just depends on the look you're going for. Our auto parts store has a wide selection in stock; check out our inventory to find the right set for your model.
