Upgrade cab access on your lifted truck with the AMP Research PowerStep XL electric running boards, part number 77154-01A. Designed for Chevrolet Silverado and GMC Sierra crew cab models, this automatic running board system combines a custom rocker rail with a wide, lower stepping surface for easier entry and exit. Its integrated design provides a clean, seamless appearance while adding practical functionality to your truck.
The PowerStep XL automatically deploys when a door opens and retracts beneath the vehicle when the door closes, helping preserve ground clearance and the truck’s streamlined profile. Built-in LED lights illuminate the stepping surface for improved visibility at night. The heavy-duty boards support up to 600 pounds and are engineered for the demands of lifted trucks. Installation requires no drilling, making it a convenient upgrade for compatible applications.
