AMP Research 77133-01A PowerStep XL Automatic Electric Running Board Black

The AMP Research PowerStep XL (77133-01A) is an automatic, electric-powered retractable running board engineered specifically for lifted trucks and SUVs. Integrated directly into a custom rocker rail, the PowerStep XL delivers a seamless, factory-style appearance while providing a stepping surface that sits 3 inches lower than the standard AMP Research PowerStep — making cab entry and exit dramatically easier on lifted applications.

Unlike fixed running boards, the PowerStep XL automatically deploys when the door opens and retracts within 3 seconds of the door closing, tucking neatly into the rocker rail with no loss of ground clearance. The step extends and retracts in under a second, and Anti-Pinch technology detects obstructions during extension for added safety.

Key Features:

• 600 lb. load capacity — twice the capacity of most competing steps
• 6-inch wide stepping surface for secure footing in any footwear
• Built-in OEM-style LED illumination activates on deployment and shuts off on retraction
• Die-cast aluminum construction with anodized, military-grade PTFE (Teflon) coating for maximum corrosion resistance
• Precision stainless steel pivot pins and maintenance-free, self-lubricating bushings for all-weather performance
• Weatherproof OEM-quality electric motors and fully integrated wiring harness
• No-drill, plug-and-play installation with included direct-fit wiring
• Finish: Black textured powder coat
• Color: Black
• UPC: 815410014055

Backed by AMP Research's 5-year / 60,000-mile warranty, the PowerStep XL is built to withstand severe driving conditions. The boards retract into the integrated rock rail housing, providing rocker panel protection and preserving ground clearance when not in use — the ideal solution for lifted rigs that demand both function and a clean, aggressive look.
