AMP Research BedStep Review: Long-Lived Step, Poor Instructions

Buy the AMP Research BedStep if you climb into your bed every week and your truck has no factory step at the back. It's a manual step with no motor and no wiring: it bolts to the frame under the rear bumper, you kick the pad down and it swings out at the corner, and you push it back up with your toe when you're done. The step is the strong part. It holds full-size adults, it works with the tailgate up or down and with a trailer on the hitch, and its long-term record runs past a decade.

The weak part is getting it on the truck. AMP's install instructions are poor, part numbers are easy to mix up, and a dual exhaust or a crooked bracket can spoil the fit. AMP's own Amazon listings cover the Gen13 F-150, the Ram 1500 DT (two listings) and the 3rd gen Tacoma. AMP also sells the BedStep2, a different step that mounts on the side of the bed behind the cab, and the motorized AMP Research PowerStep running boards for the cab. This review covers the bumper-mounted BedStep, and we label anything about the others.

The short version

What works:

• Tailgate up or down: it works either way, and with a trailer hitched, which a tailgate step can't match.
• Nothing to wire: no motor, no controller, no switch. Your foot deploys it and your toe stows it.
• Strength: AMP rates it at 300 lb, and owners around 200 to 220 lb call it solid.
• Track record: older BedSteps have kept working for six to 11 years.

What to watch:

• Instructions: vague drawings, extra holes that aren't used, and bolts a torque wrench can't reach on some trucks.
• Part numbers: the wrong one for your year or bumper can sit crooked or hit the bumper when stowed.
• Exhaust: a dual exhaust can be in the way, including the Raptor's.
• Stepping down: from the bed you can't see it, so you feel for it with a foot.
• Warranty: three years on RealTruck's page, and it ends if the step moves to another truck or the truck is sold.

Which trucks it fits

Buy the listing for your exact truck. AMP makes one bracket kit per truck under its own part number, and Amazon lists them the same way. None of those listings restricts bed length or cab; the fitment table has the part numbers.

For the 13th-generation F-150 (Gen13), part 75312-01A reads 2015-2020. For the DT Ram 1500, 75322-01A covers 2019-2024 and excludes the TRX, and 75331-01A covers 2025-2026 and excludes the RHO and TRX. Neither Ram listing covers the Ram 1500 Classic (DS). For the 3rd gen Tacoma, 75317-01A reads 2016-2021, so 2022 and 2023 Tacomas fall outside it. RealTruck does list an AMP BedStep for a 2022 Tacoma, so ask AMP which part fits before you order for one of those years.

RealTruck sells an AMP BedStep for the 14th-generation F-150 (Gen14), which an AMP dealer lists as part 75328-01A. On Amazon, every listing we found under that number was a look-alike copy, not AMP's step, and we don't recommend the copies. The Gen14 row is a search link: check fit for your truck, and buy from an AMP dealer if Amazon still shows only copies. RealTruck's AMP pages also list a BedStep for the 3rd gen Tundra and for the T1XX Silverado 1500, without a part number, and we haven't confirmed an Amazon listing for either. Those rows are search links too. No BedStep is listed for the 4th gen Tacoma, the Maverick, the 2024 Ranger or the 2024 Colorado and Canyon. Toyota sells its own bed step for the 4th gen Tacoma, which we haven't reviewed.

Part numbers matter more here than with most gear. On the previous-generation Tundra (2014-2021), owners who were sold the part meant for resin-bumper trucks found the step hit the bumper or sat crooked when stowed, and AMP pointed them to a different part number that fit cleanly. We don't cover that truck, but the lesson carries over: match the part to your year and bumper, and call AMP if the listing and your truck disagree.

Check your exhaust before you order. The step sits at a rear corner, and a dual exhaust puts a tailpipe at both. A Gen14 owner who moved to a Raptor pulled the BedStep because it won't work with the Raptor's dual exhaust, and a Gen13 owner warns it may be in the way if you ever add a dual rear exhaust. None of AMP's four Amazon listings mentions exhaust, so ask AMP if your truck has dual tips.

The specs that matter

AMP publishes little about the BedStep, and the 300 lb figure is the headline. RealTruck's product page says the frame supports up to 300 lb, without saying how that's measured. The same page calls the frame both high-strength aluminum alloy and die-cast aluminum, and describes a glass-reinforced step pad pitched for traction in rain, snow and mud. The Amazon listings add stainless steel pivot pins and self-lubricating bushings, which they call maintenance-free. AMP publishes no weight and no install time. AMP says the BedStep bolts on for most applications, that some need minor drilling, and that step orientation may vary by truck.

Count what you carry against the rating. The 300 lb figure covers you and anything in your hands, so a 220 lb owner hauling a 60 lb bag of concrete up the step is at 280 lb. Near the limit, set the load on the tailgate or bed rail first and climb up empty-handed.

Read the warranty as three years, not five. AMP's warranty page sends you to each product's own page for the term, and RealTruck's BedStep page gives a 3-year limited warranty that can't be transferred and expires if the step comes off the original truck or the truck goes to a new owner. AMP's Amazon listings say 5-year/60,000 mile instead. The product page governs, so we go by three years; if the longer term matters to you, get AMP's answer in writing before you buy.

Using it: footing, clearance and getting down

We like the BedStep most for what a tailgate step can't do. It works with the gate closed, so you can reach into the bed over it, and with the gate down, and a hitched trailer doesn't get in the way. Owners who've had Ford's factory tailgate step and the BedStep mostly prefer the BedStep for that reason, and it keeps the step's weight out of the tailgate. A Gen14 owner whose truck came with the tailgate step found it useless the first time 8 ft lumber lay across the open gate.

Getting down is the weak moment. From the bed you can't see the pad tucked at the bumper corner, so you feel for it with a foot. Some owners never notice; others call it the one downside. Turn and face the truck on the way down and keep a hand on the bed rail.

Check the stowed position on install day. On one Ram 1500 DT the step doesn't sit perfectly level when retracted, and on one Tacoma a crooked bracket left it out of line with the bumper. Ask AMP about adjustment before you grind or shim anything.

Fold it up before you drive. A step left down usually gets bumped back up by a light drag, but backing into something with it out will wreck it.

Build quality and living with it

We think the BedStep is built to outlast most trucks it goes on. Long reports are the best part of its record: 11 years on one truck, eight on a 2012 Tundra by the sea, six on another. Those are older steps on older trucks, so read them as proof the design lasts, not a promise about this year's bracket. The pad is the part that breaks. A step that had been on a 2010 F-150 since its owner bought the truck cracked its pad, and nothing else on it failed.

AMP calls the bushings self-lubricating and maintenance-free. Owners near salt water or salted roads still treat theirs: one by the sea lubed the pivots now and then and treated the frame with a rust converter and bedliner paint, and another sprays the frame and mounting hardware with Fluid Film twice a year. A step that sits unused for months may also turn stiff. Rinse it when you wash the truck, and ask AMP what it allows before you spray anything into the pivots, since it's AMP's warranty at stake. The hardware deserves a look too: one owner says the supplied bolts have no coating.

AMP support is hit and miss. When it works it's quick: a tech can talk you through a confusing bracket in minutes, and a missing or duplicate part gets replaced. When it doesn't, you wait for a call that doesn't come, or you're told the step was modified. Keep photos of every install step until the job is done.

How it compares

If your F-150 already has Ford's tailgate step and you rarely haul long loads, you can skip the BedStep. Ford's step only works with the gate down, but it comes with a grab handle and you can see where you're stepping. One owner who ran an AMP step on a Chevy prefers Ford's step for that reason. For everyone else, the BedStep's always-there corner step wins.

On a DT Ram, price Mopar's bed step before you decide. Ram owners who chose it call it sturdy and like how little of it shows when stowed. We haven't reviewed it and have no verified listing to link, but if your dealer prices it close to the BedStep, it's a fair alternative. Toyota sells its own bed step for the Tacoma and Tundra, which owners say AMP builds; we treat it as a separate product. Bestop's TrekStep, compared mostly on previous-generation Tundras, has a larger, grittier pad, while one F-150 owner found the AMP tucks up better.

Skip the copies. One previous-generation Tundra owner's Amazon copy snapped on the fifth climb at 170 lb; others report theirs are fine, and you can't tell in advance which one you'll get. Rough Country's Retractable Bed Step is a different case: a branded step on the same idea for noticeably less, with listings for the Gen13 F-150 and the 3rd gen Tacoma. We haven't reviewed it, and one owner who tried one before the AMP found it didn't line up with the bumper and touched the hitch, so check the fit before you rely on it.

The BedStep2 does a different job: it mounts on the side of the bed so you can reach the front of the bed without climbing in. It carries the same 300 lb rating and 3-year limited warranty, and costs about the same. We haven't reviewed it. The AMP Research PowerStep solves the climb into the cab, not the bed. It's motorized, wired to the truck, costs much more and carries a 5-year limited warranty. Some owners run both.

Installing it

Read AMP's vehicle-specific guide twice before you crawl under the truck, and follow it. Bolt torque comes from that guide, not from us or a forum post. On most trucks the BedStep bolts to the frame or the bumper bracket at factory bolt locations; AMP says some applications need minor drilling. AMP publishes no install time; one Tacoma owner was done in 15 minutes, while owners fighting the instructions needed several tries.

• Towing from the same mounts (Gen13 F-150): the step shares the mounting points of the bumper and hitch bracket. Early Gen13 owners found the factory studs left only about two threads on the nut once the step's bracket was added, a real concern if you tow from the factory hitch; one fitted longer bolts, while other owners, one on a 2018, found the bolts plenty long and the nuts fully engaged. Before you tow, check that each nut fully engages its stud. If it doesn't, stop and ask AMP and the hitch maker what hardware to use, and follow AMP's install guide and the hitch maker's instructions. Never improvise hardware on a towing mount, and never tow past the lowest rating in the chain.
• Brackets and holes (Gen14 F-150): the support bracket has two holes, but only one bolt goes through it. AMP's tech support confirmed that layout to an owner who was stuck, and an owner who enlarged frame holes to fit both bolts was then told the step had been modified. Don't drill to make it fit; call AMP first.
• Bolts you can't reach: on some trucks one bolt won't take a torque wrench or a 6-point impact socket. If you can't tighten a bolt the way AMP's guide specifies, call AMP before you guess.
• Factory brackets (previous-generation Tundra): AMP's kit swaps a factory bracket for its own. Owners who cut the factory bracket instead say it spares the worst of the job, but that's off the instructions, and we'd follow AMP's guide.

If your truck tows from the factory hitch and you'd rather not judge stud engagement yourself, pay a shop that has fitted one to your exact truck, and check the nuts again before the first tow.

Who should bolt one on

Buy the BedStep if you're in and out of the bed every week, haul with the tailgate up or a trailer on, and your truck has no factory step at the back. Buy the exact part for your year, check your exhaust, and set aside an afternoon with the instructions and AMP's phone number. On a DT Ram, price the Mopar step too. If your F-150 has Ford's tailgate step and you rarely carry long loads, keep your money.

Whichever you buy, stow it before you drive and rinse it with the truck.
