That's 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. AMP RESEARCH SILVERADO 2500 3500 POWERSTEP INCREASES FUEL EFFICIENCY. There are few topics more rampant and heavily discussed than soaring gas prices, and the effect they have on today's trucks & SUV's. Since aerodynamic drag and weight are two critical factors that impact fuel efficiency, truck owners are now seeking ways to reduce these variables. The AMP Research PowerStepT can do both, and still allow you to maintain the convenience and safety of full-length running boards that automatically deploy for optimal ingress and egress. Reducing the overall weight of your vehicle can also help improve gas mileage. AMP's high-strength aluminum steps weigh 10-20% less than typical OEM running boards or aftermarket steel tube steps. AMP's 2017 2018 2019 SILVERADO 2500 HD 3500 HD PowerSteps or running boards work automatically and improve safety and comfort while entering and exiting your truck. They are activated by your truck's factory door sensors and extend within a few seconds when you open the door. Closing the door automatically retracts the PowerStep into the rocker panels, eliminating the drag produced by traditional stationary running boards. AMP's PowerStepT technology has been utilized as a factory option since 2003. The AMP Research PowerStep extends out and down when you open your doors and retracts in and up when they close. Boards extend 10 to 12 inches for a comfortable, natural-feeling step area. Keeps your full ground clearance when retracted. Steps made from high-strength aluminum. Holds up to 600 lbs. AMP PowerStep bars extend fully in one second. Motors are weatherproof and durable. Works in extreme heat, ice, and snow conditions.
