"The original power-retractable running boards since 2002—now with an extra drop built specifically for lifted trucks and taller rides. The AMP Research® PowerStep™ XL delivers everything the standard PowerStep is known for, with one critical addition––the boards deploy up to three inches lower than the standard PowerStep, making entry and exit significantly easier on lifted vehicles where the standard step height falls short.?Built to perform year after year, the PowerStep XL running boards are constructed from corrosion-resistant aluminum with an advanced powder coat finish engineered to withstand tough daily use without degrading. Stainless steel hinge pins and hardware add long-term durability where it counts. Each board supports up to 300 lbs. per door—the same proven load capacity as the standard PowerStep, in a platform sized for bigger builds.?The PowerStep XL deploys and retracts automatically in harmony with how you use your vehicle—extending when the door opens, and retracting tight and out of sight the moment it closes. A 6-in.-wide step delivers a stable, slip-resistant platform, and integrated LED lighting illuminates the step surface for confident footing in low-light conditions. ?AMP Research's patented plug-n-play design connects directly to your vehicle for unmatched seamless integration—no improvised attachments, no complicated wiring, no magnet alignment issues. An optional override switch is available for manual control when needed. For owners already running the standard PowerStep, the XL is the purpose-built upgrade for lifted applications where that extra drop makes a real difference.?Professional installation is recommended for all PowerStep XL running boards, though experienced DIYers can complete the install at home using the included vehicle-specific mounting kit, bracketry, hardware, wiring, and instructions. Drilling is required on select applications. Backed by a 5-year limited warranty."

Fitment

  • Will this fit my truck?

    The Fits section at the top of the page lists the manufacturer's applications for this exact part. If your year, make and model is not there, or you are not sure, text us a photo of what you are replacing with your year and engine and we will confirm it before you order.

  • What if I order the wrong part?

    Call or text us before it ships and we will swap it. After delivery you have 30 days to return it in new, uninstalled condition. The return policy has the restocking details.

Shipping

  • When will it ship?

    In-stock parts usually ship within 1 to 2 business days from warehouses across the USA. The stock line under the options tells you the status of the part you are looking at. Large items ship LTL freight and we call to schedule delivery.

  • Why did I only get part of my order?

    We ship from multiple warehouses, so an order with several items can arrive in more than one box. Tracking for each shipment is emailed as it goes out. Full details in the shipping policy.

Returns and warranty

  • What is the return policy?

    30 days from delivery, in new and uninstalled condition, with a restocking fee. Everything is spelled out in the Returns & Refund Policy.

  • How do warranty claims work?

    We are an authorized dealer, so the manufacturer's warranty applies to every part we sell. Call or text us with your order number and we handle the claim with the brand for you.

Paying

  • Can I pay over time?

    Yes. Shop Pay installments are offered at checkout on qualifying orders, and the monthly estimate shows right under the price.

  • What is a core deposit?

    Some remanufactured parts, like injectors and turbos, carry a refundable core deposit. It is shown on the product page when it applies and refunded when your old part comes back to us.
