Upgrade your truck’s accessibility and exterior profile with the AMP Research PowerStep Plug-N-Play Running Boards. Featuring automatic, electric-powered deployment when any door opens and seamless retraction out of sight when closed, these heavy-duty 6-inch-wide aluminum steps preserve full ground clearance while providing a wide, slip-resistant, LED-illuminated stepping platform rated up to 600 lbs per side.
The AMP Research PowerStep Plug-N-Play Running Boards (Part #76254-01A) eliminate the compromise between rugged off-road ground clearance and effortless cab entry. Engineered specifically for select Chevrolet Silverado and GMC Sierra pickup models, this motorized running board system deploys smoothly in roughly one second as soon as a door opens, extending down and out to create a comfortable, natural stepping height. Once the doors are closed, the boards retract tightly beneath the rocker panels—protecting the lower body from road debris, reducing aerodynamic drag, and maintaining clean, uninterrupted factory body lines.
Key Features:
Plug-N-Play OBD-II Integration: Connects directly to your truck's OBD-II port via a pass-thru wiring harness, eliminating complicated wire splicing, door panel removal, or magnetic sensor alignment while retaining open access to your diagnostic port.
Heavy-Duty All-Weather Construction: Crafted from corrosion-resistant extruded and die-cast aluminum alloy components paired with stainless steel hinge pins and weatherproof OEM-quality motors. Finished in a military-grade textured black powder coat built to endure snow, ice, road salt, and heavy daily wear in Burke, VA.
Wide Traction & Integrated Night Lighting: Each board features a generous 6-inch-wide, high-grip textured tread surface for confident footing in wet or icy conditions, complemented by low-profile integrated LED step lights that automatically illuminate the platform at night.
Safety & Load Performance: Supports up to 600 lbs per side (300 lbs per door) and incorporates pressure-sensitive, pinch-proof safety technology that halts movement if an obstruction is detected.
Vehicle Fitment & Warranty: Fits 2019–2021 Chevrolet Silverado / GMC Sierra 1500, 2022 Silverado 1500 LTD / Sierra 1500 Limited, and 2020–2023 Silverado / Sierra 2500HD & 3500HD (Double & Crew Cab models). Includes all vehicle-specific mounting brackets, hardware, wiring, and instructions, backed by a 5-Year / 60,000-Mile Limited Warranty.
