AMP Research PowerStep XL Electric Running Boards Jeep Wrangler JL 4-Door | 77132-01A

Overview

The AMP Research PowerStep XL (Part #77132-01A) is the ultimate automatic electric running board engineered specifically for the 2018–2024 Jeep Wrangler JL 4-Door, including 4XE and Rubicon 392 variants. Designed for Jeep owners who demand both capability and convenience, these power-deploying running boards deliver a 3-inch lower stepping surface than the standard PowerStep — making entry and exit effortless on lifted Wranglers or even factory-height models. If you're searching for the best electric running boards for the Jeep Wrangler JL, the PowerStep XL sets the benchmark.

Key Features & Benefits

• Automatic Electric Deployment — Steps instantly extend when any door opens and retract with a 3-second delay after closing, keeping your Jeep's profile clean and ground clearance intact while driving.
• 3-Inch Lower Stepping Surface — Deploys lower than the original PowerStep, making cab access dramatically easier on lifted Wranglers — ideal for lifts of 2" or more.
• 6063 Marine-Grade Aluminum Rail Construction — Fully welded, integrated bracket system built from aerospace-grade aluminum supports up to 600 lbs. per side — twice the capacity of most competing running boards.
• Military-Spec Anodized & PTFE-Coated Finish — Step surface is anodized and coated with a military-grade PTFE finish that resists corrosion, UV damage, and daily wear — maintains a like-new appearance after years of use.
• Integrated LED Step Lighting — Dual low-profile LED lights illuminate the step surface and ground below automatically upon deployment, maximizing visibility and safety in low-light conditions. Lights shut off automatically when steps retract.
• Anti-Pinch Safety Technology — Onboard sensors detect resistance during extension or retraction and immediately halt and reverse the step motor — protecting passengers, pets, and gear.
• Patented Plug-N-Play OBD-II Integration — Connects to your Wrangler's OBD-II port via a proprietary plug-and-play module for factory-level integration. No magnets, no jerry-rigged wiring — clean, seamless, and reliable.
• Precision Stainless Steel Pivot Pins — Heavy-duty stainless steel pivot hardware delivers rock-solid stability and long-term durability even in extreme off-road and weather conditions.
• Maintenance-Free, Self-Lubricating Bushings — Weatherproof OEM-quality electric motors and self-lubricating bushings ensure all-weather, year-round performance with zero scheduled maintenance.
• Rocker Panel Protection — When retracted, the step tucks flush into a custom integrated rocker rail, providing light rocker protection while preserving full off-road ground clearance.
• American Designed & Engineered — Invented, designed, and engineered in the USA by AMP Research — the originator of the power-deploying running board category.
• 5-Year / 60,000-Mile Limited Warranty — Backed by one of the most comprehensive warranties in the aftermarket running board segment, supported by a US-based customer service team.

Frequently Asked Questions

Q: Do the PowerStep XL boards work with the Jeep doors removed?
A: An optional override switch (sold separately) is available for manual control when the doors are removed — this is highly recommended for doorless Wrangler operation.

Q: Can the PowerStep XL be installed on a Rubicon 392 with factory rock rails?
A: Yes — however, the factory-equipped OE rock rails must be removed prior to installation.

Q: Are these boards suitable for a stock-height Wrangler JL?
A: Absolutely. While engineered for lifted Jeeps, the lower deployment height makes entry even more convenient on factory-height JL models.

Q: Are the PowerStep XL boards CARB compliant?
A: This is a mechanical/electrical accessory that does not modify engine emissions systems. It is legal for use in all 50 US states. Note: California Proposition 65 warning applies — see product packaging for details.
