Description

The AMP Research PowerStep is a heavy-duty, power-retractable running board designed for trucks, Jeeps®, and SUVs. It automatically deploys when the door opens and retracts discreetly under the vehicle's body when not in use, preserving ground clearance and aesthetics. Constructed from die-cast aluminum for strength and light weight, it features stainless steel hinge pins and hardware for durability and corrosion resistance. The step surface has a military-grade PTFE coating for protection against oxidation and abrasions, providing a sleek black finish. These 6-inch wide, non-slip steps ease entry and exit, even in adverse weather, and include integrated low-profile LED courtesy lights for visibility. Each set comes with a vehicle-specific mounting kit, instructions, and, for newer applications, a plug-n-play OBD II module. Professional installation is recommended. Backed by a 5-year limited warranty.
