AMP Research PowerStep™ XL Running Boards are engineered specifically for trucks with higher ground clearance or lifted suspensions, offering enhanced accessibility with a 4-inch lower step height compared to standard PowerStep™ models. These running boards deploy automatically when the door opens and retract neatly after a 3-second delay, tucking into the rock rail for maximum ground clearance and light rocker panel protection while driving.

Constructed from corrosion-resistant die-cast aluminum and finished with a military-grade PTFE coating, the PowerStep™ XL is designed for maximum durability and strength. The 6-inch wide, textured step surface provides secure footing, even in wet or muddy conditions. Each step is built to handle up to 600 lbs, offering double the capacity of many other side steps.

For added safety, integrated LED lighting illuminates the steps and surrounding area when deployed, ensuring safe entry and exit even in low-light environments. The PowerStep™ XL includes a vehicle-specific installation guide, mounting kit, and hardware for a straightforward installation. Newer models feature a plug-n-play OBDII module for seamless integration into your vehicle's electrical system. Professional installation is recommended to ensure optimal performance.

With its rugged construction, wide step surface, and lower deployment height, the AMP Research PowerStep™ XL is the perfect upgrade for lifted trucks, providing both functionality and style.
