AMP Research PowerStep Review: Best Step Height, Fussy Install

Buy the standard AMP Research PowerStep if anyone who rides in your truck struggles with the climb and the truck sits at or near stock height. It's the power step we'd buy. Open a door and an aluminum step swings down and out on a motorized linkage; shut it and the step tucks back up under the rocker panel. What sets it apart is where it puts your foot. It drops well below the door sill, lower than fixed running boards and lower than the Go Rhino E1 it gets cross-shopped with, so short riders get an easy first step and tall drivers can slide across into the seat instead of climbing up and folding down.

The weak spot is the install, not the step. Current kits read the truck's door signals through the OBD port, and on some newer trucks that connection is where things go wrong: steps that won't come down, wire taps that are hard to identify, boards that don't sit flush when they retract. Once a set works, owners love it. Much of the long-term record comes from older PowerSteps on trucks from 2012 to 2020, so it shows how the mechanism ages rather than promising what this year's kit will do. AMP also sells the PowerStep XL, XTreme, Smart Series and Vision. This review covers the standard single-motor PowerStep, and we label any report about the others.

The short version

What works:

• The step height. It drops several inches lower than fixed boards and the Go Rhino E1, which is the reason to pay for it.
• It reads the truck's own door signals, so there are no magnets to stick on the doors.
• A short delay before it retracts lets you shut the front door and open the rear one without the step folding away under you.
• AMP publishes a 300 lb per door rating, and the 6 in wide step has LED lighting built in. The warranty runs 5 years, limited.

What to watch:

• Getting the trigger wiring right on 2025 Ram 1500s and 3rd gen Tundras, where some installs won't deploy or work only part of the time.
• Boards that sit too far from the body or off level once retracted, mostly on 3rd gen Tundras.
• The occasional noisy or weak motor, and worn gearboxes on older sets.
• A warranty that ends if the steps move to another truck or the truck changes hands, and that never covers labor.

Which trucks and cabs it fits

Buy the listing for your exact truck, and read its fitment line for cab and powertrain, because AMP sells one kit per truck and Amazon lists them the same way. Bed length doesn't matter for a step. We confirmed each fitment on the listing's own product page, and the table under the score panel has the part numbers and cab notes.

On the F-150, the Gen14 listing reads 2021-2026, names Regular Cab, SuperCab and SuperCrew, and excludes the PowerBoost hybrid; PowerBoost (2021-2024) and Lightning (2022-2024) owners have their own listing, and the Gen13 listing covers 2015-2020 in all three cabs. For the T1XX Silverado and Sierra 1500, the 2019-2021 listing names Crew, Double and Extended cabs and also lists the 2022 Silverado 1500 LD and Sierra 1500 Limited, while a 2019 Silverado LD or Sierra Limited on the carryover body needs a different listing. The 2022-2026 listing's title adds the 2500HD and 3500HD, and its fitment bullet narrows those to 2024-2026.

The Ram 1500 listing for 2019-2024 doesn't say DT or Classic. We've tagged it to the DT; if you drive a Ram 1500 Classic (DS), confirm with AMP first. The 2025-2026 Ram listing says gas only. The 3rd gen Tundra listing reads 2022-2024, includes hybrids and names no cab restriction, but read the Double Cab warning in the install section before you order. We didn't find a standard PowerStep listing that names a 2025 or 2026 Tundra; the Smart Series and XTreme listings run through 2026. The 2024-2026 Ranger and the 2023-2026 Colorado and Canyon have confirmed listings. RealTruck's AMP pages list a PowerStep for the 3rd and 4th gen Tacoma, but we haven't confirmed an Amazon listing for either, so those rows are search links: check fit for your truck. RealTruck lists no PowerStep for the Maverick.

The specs that matter

The numbers AMP publishes are few, and they're the same across the line. Every PowerStep is rated at 300 lb per door, built from aluminum with a textured black powder coat and stainless steel hinge pins, and carries a 5-year limited warranty. The step is 6 in wide. The standard model and the XL, Smart Series and Vision run one motor per side; the XTreme runs two. Only the XL has a published height difference: it deploys up to 3 in lower than the standard step. AMP doesn't say how its 300 lb figure is measured.

AMP doesn't publish the boards' weight or an install time. The product page says to consult the vehicle-specific install guide for tools and time, recommends a professional install, and says drilling is required on select applications. There's also no published figure for how far the standard step drops or for ground clearance under the retracted board, so the height claims in this review come from owners measuring their own trucks.

Read the warranty terms before you think of it as five years of cover. It ends if the steps come off the original truck or the truck goes to a new owner, and you pay the labor to remove or reinstall anything. Even when AMP covers a failed part, your installer bills you for the swap. The warranty text also carves out items "listed below under the Three Year Warranty" without showing that list, and AMP publishes no separate term for the motors, so ask AMP whether motors and controllers get five years or three before you count on either.

Step height, clearance and the electronics

Choose the PowerStep for the step height. Fixed boards sit just below the door sill, which helps a short rider and does little for a tall one, who ends up standing with their head near the roof and contorting down into the seat. The PowerStep swings down and out to roughly halfway between the rocker panel and the ground, several inches lower than the Go Rhino E1, whose board drops only a couple of inches below the sill. Owners who moved from the E1 to the PowerStep did it for that reason. On trucks with smaller wheels or a lower stock ride height, the step can feel a little close to the ground. Some tall drivers prefer a higher step they can stand on and then sit down from, and the E1 suits them.

Check the retracted position the day the steps go on, while the installer is still accountable. The standard step is meant to tuck tight against the body, and usually does. On 3rd gen Tundras, though, four owners found boards sitting too far from the cab, hanging about an inch low or refusing to sit level, and the fixes they describe come down to mounting bolts and the rear linkage. On one Ranger the steps retracted hard enough to dent the rocker panel on the motor side; RealTruck's advice was to jump on that side to bend the boards down, and the owner fixed it with homemade plastic stop blocks, one on each side next to the motor. If your step closes with a bang, stop it before it marks the paint.

The electronics are the PowerStep's weak spot, and it's the connection more than the motors. AMP says newer applications connect through an OBD II module, yet some kits still need two door-signal wires tapped behind the dash, and the 3rd gen Tundra kit won't work fully plug and play. On 2025 Ram 1500s and 3rd gen Tundras, six owners of standard or unlabeled PowerSteps describe steps that wouldn't come down, worked only some of the time, or deployed when the door shut. Some of those trace back to bad wire taps or an installer's damaged wiring, and AMP's tech support talked owners through fixes; others ended with a replacement plug or controller on the way. XL and XTreme owners report the same OBD connector trouble. Owners who got through the install mostly report no trouble since.

If you run a tuner or a scan tool, buy AMP's pass-through harness, which adds a second OBD port so nobody unplugs your steps during a dealer software update. With the AMP plug pulled, the steps stay retracted.

We can't vouch for the PowerStep in snow country, because the owner record there is thin, and nobody in it describes a step frozen in place. Grit is the documented nuisance: small pebbles from sanded roads can lodge in the linkage joints and stop a step, so rinse the boards through the winter and pick out any stone that jams. AMP's care instructions, published with the PowerStep XL, say to pressure wash the linkages at all four hinge points without spraying the motors directly, and not to lubricate with grease, oil, WD-40 or penetrants. Some installers recommend grease anyway. Follow AMP; it's AMP's warranty.

Build quality and living with it

We think the step itself is well made and the mechanism is simple enough to keep running. Owners call it solid and stable, and the long reports are good ones, with sets running for years without trouble and owners who went back to fixed boards missing them. Those reports describe older versions on older trucks, so take them as evidence the design can last, not a promise for this year's kit.

The failures that do show up are mechanical and mostly minor. A motor can turn noisy or start clicking early, a step can stall partway up, and on older sets the gearbox on the motor linkage and the linkage's lower mounting point have both given out. The steps are louder than some owners expect. On corrosion, AMP specs corrosion-resistant aluminum, a powder coat and stainless hinge pins; one owner reports the black coating coming off. Replacement motors are easy to find and inexpensive; a gearbox housing on its own is harder to source than a full linkage.

Expect to call AMP at least once, and expect a wait. Phone holds can run over an hour, so leave a message and wait for the call-back. Once AMP diagnoses a problem, it sends the parts. The 5-year limited warranty should catch an early failure, as long as the steps stay on the truck you bought them for; confirm with AMP how long the motors and controller are covered.

How it compares

Pick fixed running boards or nerf bars if you'd rather have nothing to wire and nothing to fail, and accept the higher step. The price gap is substantial, and we'd still pay it for any rider who can't use a fixed step.

Choose the PowerStep over the Go Rhino E1 if step height is the reason you're shopping. The E1 triggers from magnets on the doors, retracts with no delay and sits only a couple of inches below the sill. Its owners report good quality and an easy install, and tall drivers who like a high step and a short drop into the seat may prefer it. Both brands belong to RealTruck. Westin's Pro-e is a dual-motor board that one buyer put at about the price of AMP's dual-motor XTreme; we have no side-by-side owner reports to settle which is better, and the same goes for Rough Country's dual-motor boards.

Within AMP's line, the standard step is the one to buy unless one of the siblings fixes a specific problem. The XL deploys up to 3 in lower and costs noticeably more. It suits a properly lifted truck, but on a Tundra with a 3 in factory lift one owner found the XL too low and went back to the standard step. The XTreme adds a second motor per side, which AMP pitches for snow, ice and mud. Owners give conflicting answers on whether it works on the Tundra hybrid, so get AMP's answer in writing before you buy one for a hybrid. The Smart Series replaces the physical override switch with a smartphone app that AMP says gives full manual override, and the Vision adds LED edge lighting that dims to color-adjustable accent lighting when retracted; both are the same single-motor step underneath. AMP's BedStep is a different product, a step for reaching into the bed, and nothing in this review applies to it.

Installing it

Pay a shop that has done your exact truck, or give the job a full day and read AMP's vehicle-specific guide before you start. Wiring and torque come from that guide, not from us or a forum post. AMP recommends a professional install for every PowerStep application and doesn't publish an install time. The work splits into bolting the motor linkages and idlers to the body, hanging the step on the linkages, and running the harness to the battery, a controller under the hood and the OBD port.

• Drilling. AMP says some applications need it. The 2025 Ranger instructions call for a hole through the floor under the carpet, according to an owner who read them, and the 3rd gen Tundra kit's rear brace requires drilling. On the Tundra hybrid, one owner got the positive cable's ring terminal into the fuse box without drilling by prying the plastic housing apart and trimming a small piece of plastic that fouled the wire. Work in the fuse box only as AMP's guide for your truck directs.
• Wire taps. Identifying the right blue and white wires takes time, and the instructions don't always match the wires in the kit. Take photos before you tap anything and go slowly.
• Tools. Some Tundra kits use security Torx bolts on the brace that the instructions don't mention.
• Override switch. AMP sells an optional switch for manual control. The manual positions time out back to automatic, so it's easy to skip; you can hold the step down with a foot while shutting the door when you need it out.

Double Cab Tundra owners should talk to AMP before ordering. The linkages are identical side to side, which puts the driver-side motor facing forward, and on one Double Cab a stub on the frame blocked the driver-side bracket from reaching the body. The only fix on offer was cutting the stub off the frame. We haven't seen the problem on a CrewMax, where the bracket sits farther back.

A shop install isn't a guarantee. Some of the trigger failures came from professional installs, including one traced to the installer's damaged wiring, and the misaligned Tundra boards were installed locally. Ask any installer how many PowerSteps they've put on your exact truck, and test every door before you pay.

Who the PowerStep is for

Buy it for a truck at or near stock height when step height matters to someone who rides in it, and budget either a day or a good installer. That's the job it does better than fixed boards and better than the power boards that drop only a couple of inches. If you run a lift of 6 in or so, look at the XL instead. If you want nothing with a motor under the door, buy fixed boards and live with the higher step.

Whichever way you go, check the gap and level on day one, open every door to make sure its step deploys, and rinse the linkages after winter driving.
