Getting into your truck shouldn't feel like climbing Mount Everest.

That's why AMP Research invented the patented PowerStep™, the automatic, electric-powered running board that instantly extends when you open your door, and retracts out of sight when the doors close for improved ground clearance, aerodynamics and appearance.

Its sleek design, all-weather performance and legendary reliability set the industry standard.

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.

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.

*** The Power Step is designed to operate normally in all weather conditions and is built to handle up to 600 lbs. per side.
