Premium Powered Running Board for HD GM Trucks

Got a lifted rig or work truck that demands more than just your average step? The AMP Research PowerStep Extreme is built to handle exactly that, and then some. Designed specifically for the 2020–2025 Silverado and Sierra 2500HD/3500HD, this heavy-duty running board is engineered for serious performance in harsh conditions. Whether you're dealing with snow-packed wheel wells, muddy trails, or bitter cold mornings, this step deploys with confidence thanks to dual motors on each side that deliver extra torque exactly when it’s needed. Once you open the door, the PowerStep Extreme drops down automatically to give you a wide, sturdy stepping surface. Close the door, and it tucks itself neatly away, preserving ground clearance and keeping your truck’s profile clean. It's cab-length for full access across the entry, and the black textured finish isn’t just for looks, it helps resist corrosion and adds grip under your boots, even when wet or icy.

Heavy-Duty Construction & Design

Underneath, the structure is made from aircraft-grade aluminum for long-term strength without adding unnecessary weight. AMP also integrated weather-sealed motors and reinforced linkages so the system can handle brutal winters or dusty off-road trails without flinching. And with built-in LED lighting, nighttime entry is safer and more convenient. If you’re running a serious setup and need gear that can keep up, the PowerStep Extreme isn’t just a step, it’s a purpose-built upgrade. Backed by AMP Research’s 5-year/60,000-mile limited warranty, this system is built to go the distance, just like your truck.
