The AMP Research PowerStep XL(TM) 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(R). This allows easier access to and from the vehicle's cab. Learn about the PowerStep XL and its features and benefits in this new video.
