AMP Research PowerStep XL Electric Running Boards Jeep Wrangler JL 2-Door, Black w/ LED | 77133-01A

Overview

The AMP Research PowerStep XL (77133-01A) is the ultimate automatic power-retractable running board engineered specifically for the 2018–2024 Jeep Wrangler JL 2-Door. Designed for lifted Jeeps and oversized builds, the PowerStep XL deploys lower than any other retractable step on the market — placing the stepping surface a full 13 inches below the sill plate — making effortless cabin entry and exit a reality for every passenger, regardless of lift height. If you want to add a step to your Wrangler JL without sacrificing hard-won ground clearance, the PowerStep XL is the definitive solution.

Key Features & Benefits

• Lower Step Height for Lifted Vehicles — The XL drops lower than standard PowerStep models, placing the stepping surface 13" below the sill plate. Strongly recommended for Wranglers running 6"+ lifts and 36"+ tires.
• Automatic Deployment in Under 1 Second — Steps instantly extend the moment a door opens, then retract automatically after a 3-second delay when the door closes — no switches, no effort.
• 600 lb. Load Capacity Per Side — Built from high-strength die-cast aluminum alloy with a fully welded/integrated bracket system and precision stainless steel pivot pins for rock-solid stability — nearly twice the rating of most competing steps.
• Military-Grade Corrosion Protection — All aluminum components are first anodized, then coated with a military-grade PTFE (Teflon) finish, delivering exceptional rust and corrosion resistance even in harsh off-road and winter conditions.
• 6-Inch Wide Textured Step Surface — The broad, high-texture powder-coated step surface provides a secure, slip-resistant platform for all footwear types, giving every passenger a confident foothold.
• OEM-Style Integrated LED Illumination — Low-profile LED lights are built directly into the step rail, casting a clean, factory-quality glow that illuminates the step and surrounding ground for safe entry and exit in any lighting condition.
• Anti-Pinch Safety Technology — Pressure-sensitive pinch-proof sensors detect obstructions up to 15 inches during extension and retraction, immediately reversing direction to prevent injury or damage.
• Seamless Rocker Rail Integration — The step assembly integrates into a custom rocker rail housing, creating a rugged, factory-finished look that protects your rockers and blends naturally with your Wrangler's body lines.
• Weatherproof Drive System — Maintenance-free, self-lubricating bushings, sealed motors, and weather-tight connectors ensure consistent all-season performance through mud, water, snow, and trail abuse.
• 5-Year / 60,000-Mile Warranty — AMP Research backs every PowerStep XL with one of the most comprehensive warranties in the power running board segment.
