No other running board, tube step or nerf bar can match the ease of entry of the AMP RESEARCH PowerStep. Open the door and this full-length running board automatically deploys for easy stepping in and out of the cab. Close the doors and this sure-footed step platform retracts safely under the truck with no loss of ground clearance. AMP RESEARCH Power Step running boards are triggered by an electronic signal from the vehicle's factory door sensors and extends to a convenient stepping height in one second. The Power Step running boards are powered by a heavy-duty, weatherproof motor. The Power Step is lowered when any door is opened and Power Step retracts when any door is closed. At the optimal ergonomic height for proper entry and exit without sacrificing ground clearance, it provides a natural step similar to steps found in your home. All AMP RESEARCH Power Step running board components are OEM quality and corrosion-resistant for long service life. The AMP RESEARCH Power Step is designed to operate normally in all weather conditions and is built to handle up to 600 lbs. per side.
