    Add the ultimate touch of luxury to your pickup truck or sport utility vehicle with stylish, power-operated running boards that extend outward when you need them, then retract neatly out of sight underneath your vehicle when you don’t. AMP Research has engineered and built all fixed and moving PowerStep™ components to very high standards – so much so that Ford and General Motors offer these very running boards as an OEM factory option on their own vehicles. They are perfect for 4x4 owners who need maximum ground clearance during off-roading and for those who prefer not to alter the original lines of their vehicle with fixed running boards. Whatever the length of your truck’s cab, AMP Research offers running boards sized to fit your make and model that achieve an OEM-quality fit.

    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.

    The running boards are made with durable, die-cast aluminum and capable of supporting up to 600 pounds of weight. The steps boast a textured powder coat finish that resists rust and corrosion and helps with foot traction. The steps are powered by a weather proof motor with equally weatherproof wiring. The steps' stainless steel pivot pins are maintenance-free, too. Most applications feature an easy to follow plug-and-play installation using your truck's diagnostic (OBD-II) port. Plug-and-play applications also feature a pass through adapter so you can still use the port for other hardware. All applications come with detailed installation instructions.

    Founded in 1980 in southern California, AMP Research® came together with a wealth of engineering talent drawn from company founder Horst Leitner and others who were previously involved in motorcycle racing and engineering. During the 1980s and 1990s, AMP Research pioneered the first 4-stroke engines for off-road motocross bikes as well as other suspension and chain torque advancements for bicycles and motorcycles. Hauling dirt bikes to racing events in the back of their pickup trucks, company engineers rigged up temporary bed extenders to keep chairs and other items from sliding out on the road when tailgates were down. What they did worked so well, AMP Research patented the idea and introduced it for 1998 - quickly becoming a supplier to vehicle manufacturers that offered the bed extenders as factory equipment. During the following decade, AMP Research pioneered power retracting running boards and has become a featured supplier to major automakers who use them as well. AMP Research is ISO 9001:2008 certified for best business practices in manufacturing and customer satisfaction, and their range of high-quality products is widely respected throughout the industry. CARiD is proud to offer the best values on the full AMP Research lineup of power retracting running boards, step pads, bed extenders, and all individual replacement parts at prices that can’t be beat.
