The PowerBoard is an automatic running board that hides underneath your truck when doors are closed and extends to meet your foot when door opens. PowerBoards are full length, and work with all doors; front and rear, driver and passenger. The Bestop PowerBoard has a 3 year/36,000 mile limited warranty. The PowerBoard step descends up to 6 inches, which provides a comfortable stepping height. All PowerBoards include bright LED lights, automatically lighting the PowerBoard when it’s needed.
