AMP Research PowerStep: Which Part for Which Truck, and What the Warranty Says

Who is behind AMP Research

AMP Research belongs to RealTruck, which calls it its "leading powered-step brand" in a September 2022 release. The same release says the company was founded 33 years earlier as a research and development firm for motocross bike parts, by Horst Leitner, and that a new manufacturing facility opened in Brea, California. The guide we read for one current part says "Designed and manufactured by RealTruck AMP Research" and "Made in Mexico". That line covers that part, and we did not check where the others are built.

That is why Amazon titles say either AMP Research or RealTruck PowerStep.

Pricing sits in the premium class across the board. We do not print amounts.

Which part for which truck

Read 2 November 2026. Listing columns are title wording.

We have no AMP listing in our data for a 2020-2021 GM 1500, a 2021-up F-150 or a 2019-2024 Ram 1500. That means not in our data, not that no such part exists. Five of the six titles name no cab, so the last check belongs on the listing. Guides for other trucks are on the Ram and F-150 power step pages. Check your exact year and cab on the listing before you buy.

The powered step with the clearest paperwork in our data: a maker install guide that names cabs, tools and time.

Why here: We could read RealTruck's own guide for this application, which names cabs, tools, time and warranty.

Why it makes the list

• RealTruck's install guide states a 5-year limited warranty and connects through an OBD II plug
• The guide lists every cab: 79-inch board for Crew, trimmed for Double and Single Cab

Watch out for

• The guide calls for drilling through the pinch weld and rates the job skill level 4 (experienced)
• Professional installation recommended; the guide states 3-5 hours
• The title gives no part number, so match 76255-01A on the listing
• Premium price class

Best for: Owners of a 2022-up Silverado or Sierra 1500 who want a step that folds away and accept a harder install.

One honest catch: the listing title names no part number. We tied it to 76255-01A through the application, Silverado 1500 and Sierra 1500, all cabs, 2022-2026. Confirm the part number on the listing. The guide also has a line about Sierra 2500/3500 that looks wrong, so we do not use it.

What the install asks of you

• Time and skill: 3-5 hours, skill level 4, "Experienced", professional installation recommended.
• Drilling: a 1/8-inch pilot hole, then 19/64-inch through the pinch weld, in the step that marks holes for the light wires. The guide says to deburr and paint the holes.
• Wiring: a harness to the battery and body ground, two wire taps at connectors in the driver side kick panel, and a module in the OBD II port.
• Cutting: the board comes at 79 inches for a Crew Cab. A Chevy or GMC Double Cab gets trimmed 10 inches to 69, and a Single Cab 29 inches to 50.

"Plug N' Play" is in one title. In the guide we read, the plug is one step among many. The guide's warning is plain: fail to follow the instructions and you could put occupants in a potentially dangerous situation.

Living with it

Per the guide, the step deploys when a door opens and stows when it closes, with a 2-second delay. If something blocks it, it stops. Clear the obstruction, then open and close the door to reset. In mud, dirt or salt, debris can get trapped and make noise. The guide says to avoid spraying the motors directly, to use silicone spray on the hinge pivot pins after washing, and not to put silicone or wax on the stepping surface. Keep your hands away while it moves.

Other AMP listings

The Ram 1500 page explains the 2025 split for that truck, the F-150 page has the cab question for Ford, and the Silverado page covers the 2019 LD trap, which matters when a title says "2019" alone.

Warranty, parts and support

The guide for 76255-01A states five years from date of purchase, "provided there has been normal use and proper maintenance", and "applies to the original purchaser only". You keep proof of purchase and send a copy with anything returned for warranty work. Remedies are limited to repairing or replacing the part. Damage from accidents, negligence, misinstallation or misuse is not covered. The guide asks you to register the product with RealTruck and lists a tech support line for warranty issues.

Your truck's factory warranty is a separate matter. The FTC said in 2018 that conditioning coverage on specified parts is generally prohibited under the Magnuson-Moss Act, with exceptions. Ford says an aftermarket part "will not necessarily void" its warranty, but repairs for damage it causes are not covered. None of this is legal advice.

The PowerStep XL and load ratings

Who should buy, and what else to look at

Buy AMP if your truck has a listing that names it, you want a step that tucks away, and you accept a premium class and a real install. Skip it if you want a weekend bolt-on.

Other powered choices: Westin states "no-drill" and "300 lbs. of weight capacity per side" for its Pro-e, on its own page. The Rough Country^* listing for GM crew cabs ties to a sheet by application only. The WOLFBOX^* GM title names no years, and WOLFBOX's page fills in some of that. Our comparison is on power running boards. All trucks are under all trucks, and our rules are on how we verify fitment. Check your exact year and cab on the listing before you buy.

The XL parts have their own page at PowerStep XL, and power running board problems covers what to check when a step stops.
