Product details

"The original power-retractable running boards since 2002—and the most powerful PowerStep ever built. The AMP Research® PowerStep™ Xtreme running boards take everything proven about the standard PowerStep and add a dual-motor design engineered to power through snow, ice, mud, and debris, delivering consistent, reliable operation where single-motor boards struggle. If you live in or regularly drive in harsh conditions, this is the PowerStep built for you. ? Like all PowerStep variants, the Xtreme running boards are constructed from corrosion-resistant aluminum with an advanced powder coat finish engineered to handle tough daily use year after year. Stainless steel hinge pins and hardware add long-term durability at every pivot point. Each board supports up to 300 lbs. per door—the same proven load capacity as the rest of the PowerStep family. The dual-motor design is the defining upgrade—two motors per side deliver the extra torque needed to operate reliably in demanding environments where ice buildup, packed snow, or debris would slow or stop a single-motor board. Beyond the drivetrain, the Xtreme shares the full PowerStep feature set—a 6-in.-wide slip-resistant step surface, integrated LED lighting for confident footing in low-light conditions, and automatic deployment and retraction that keep lines clean and ground clearance maximized when the boards aren't in use. ? AMP Research's patented plug-n-play design connects directly to your vehicle for unmatched seamless integration—no improvised attachments, no complicated wiring, no magnet alignment issues. An optional override switch is available for manual control when needed. Vehicle-specific fitment ensures a flawless fit right out of the box. ? Professional installation is recommended for all PowerStep Xtreme running boards. All hardware, bracketry, wiring, and vehicle-specific instructions are included. Drilling is required on select applications. Backed by a 5-year limited warranty." "The original power-retractable running boards since 2002—and the most powerful PowerStep ever built.
