AMP Research 77104-01A PowerStep XL

GETTING INTO YOUR TRUCK SHOULDNT FEEL LIKE CLIMBING MOUNT EVEREST. Thats why AMP Research invented POWERSTEP, the automatic, electric-powered running board that instantly extends when you open your door, and then hides itself safely out of sight when the doors close for improved ground clearance, aerodynamics and appearance. Its handsome design, all-weather performance and legendary reliability set the industry standard. Ditto its industry-leading 5-year/60, 000-mile warranty.

  • Fits 1999 - 2001 and 2004 - 2007 Ford Super Duty F250, F350 and F450 Super Crew
  • PowerStep XL
  • Black
  • Incl. OEM Style Illumination


    Amp Research PowerStep 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.
