The AMP Research PowerStep XL is an extended length retractable electric-powered running board that instantly extends when you open the door.

Invented, engineered, and built in America, the AMP Research PowerStep XL has been tested and proven to perform. The heavy-duty OEM quality electric motor provides decades of reliable, maintenance free operation and the stainless steel hinge points and bearings ensure flawless performance. These lightweight, yet rock-solid running boards feature rugged die-cast linkage components that are made in the USA of aircraft-quality aluminum and are black-anodized and PTFE coated for maximum corrosion protection in the snow, ice, dust, mud, and dirt. These extruded aluminum steps feature full-length internal ribs for rock-solid stiffness, and a high-texture powdercoat finish for maximum grip and durability. With a 600lb load capacity per side and maintenance free, self-lubricating bushings, the PowerStep XL is built to last and gives you the ultimate in styling and function.
