The 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. This allows easier access to and from the vehicle's cab. Fits 2007-2014 GMC Sierra 2500 HD, 3500 HD, 2007-2013 Chevrolet Silverado 1500
