A running board is a step that fits under the side doors of a car or truck and assists as you enter into higher clearance vehicles. Unlike a step bar that offers individual steps, the running board uses one long step for each side of your vehicle. We have running boards made with aluminum and plastic that ensure a great fit for select truck and SUV models. If you want to add a running board to your vehicle, check out our selection at O'Reilly Auto Parts. We also offer electronic running boards that extend down when your door is opened and raise back up once the door is shut. Browse our options and find a running board that works best for your vehicle.
