Amp Research PowerStep(TM) XL Running Boards take the style and convenience of traditional running boards to the next level. As the name implies, these automated boards extend when your cab door is opened and tuck away when the door is shut. The extending and retracting happens quickly - in less than a second - so you're not waiting around. Unlike the base Powerstep model, these are designed to hang even lower - making them great for lifted trucks.\nNon Plug N Play System-Includes OEM style illumination-Crew Cab Only\nThe AMP Research PowerStep XL? automatic electric-powered running board is designed for lifted trucks. The board has been integrated into a custom rocker rail and creates a seamless look while providing a 3? lower stepping surface than the original PowerStep?.
