For you if: you climb the rear bumper to reach the bed often, you want the step to disappear under the bumper when you are done, and your truck is on AMP’s BedStep chart for the matching SKU.
Skip this page if: you want AMP PowerStep running boards along the rocker. Skip nerf bars and flat fixed boards. Skip if you only want a hitch-receiver step (see the Westin HDX chip below). Skip Raptor and dual-exhaust apps excluded on the install guide for your year.
01 · Retractable under-bumper bed step
AMP Research BedStep
300 lb load rating. Aluminum alloy frame. Glass-reinforced non-slip pad. Kick to deploy / kick to stow. 3-year limited warranty. Shop example: 75312-01A (2015–2020 F-150, excl. Raptor). 75328-01A (2021–2023 F-150 class — confirm year/exhaust on AMP / RealTruck) is not this Amazon button.
Westin HDX Drop Hitch Step 56-10015 — universal 2 in receiver hitch step, not an under-bumper BedStep. Westin’s page for that part does not print a step load rating. Do not treat it as a 300 lb AMP BedStep substitute.
The ones that matter
Bed access at the bumper is different from cab entry. PowerSteps and nerf bars get you into the doors. A BedStep gets you into the bed over the bumper without a milk crate.
Retractable under-bumper vs hitch step
AMP BedStep mounts to the bumper structure and folds under the bumper. A hitch drop step plugs into a 2-inch receiver and hangs behind the hitch. Towing, spare tire carriers, and bumper sensors all change which one clears. If you live on a gooseneck or fifth-wheel, confirm bumper and hitch clearance before you order either style.
Load rating
AMP prints 300 lb on the BedStep product page. That is the number on this card. Westin 56-10015 does not print a load rating on its product page, so this page leaves that cell blank.
Stow when driving
AMP’s install guide attention note: stow the step when driving. A deployed step is for loading, not for highway geometry. Kick it up before you leave the job site.
Bed access without the milk crate
Most truck owners climb the bumper once or twice a week: coolers, feed bags, toolboxes, kids into a camper shell. A retractable BedStep gives a flat pad at bumper height and then disappears so you do not leave a hanging step in a parking lot.
AMP’s under-bumper mount is meant to stay clear of an open tailgate and of towing on the product-page copy. Still walk the install with your hitch head, bumper sensors, and spare-tire carrier in mind. Dual exhaust tips change clearance on some fourteenth-gen F-150s — that is why the 75328-class guide excludes dual-exhaust apps on later revs. Confirm before you drill.
PowerStep vs BedStep vs nerf
PowerStep is a rocker-panel board that deploys with the door. Nerf bars are fixed tubes under the doors. BedStep is only the rear bumper. Shoppers who land here after a “best steps” search often need cab entry instead — send them to power boards or nerf bars when the problem is getting into the seat, not into the bed.
When a hitch step is enough
If you already run a 2-inch receiver every day and you only need occasional bed access at the hitch, Westin HDX 56-10015 is the chip on this page. It is not retractable under the bumper, and Westin does not print a pound rating on that product page. For a dedicated under-bumper pad with a printed 300 lb line, stay on AMP BedStep.
Pick: retractable under-bumper bed step
Under-bumper kick-out pad
For a kick-out platform at the rear bumper that stows when you are done.
300 lb on AMP’s BedStep page. High-strength aluminum alloy frame. Glass-reinforced non-slip pad. Kick to deploy / kick to stow. 3-year limited warranty
75328-01A is the 2021–2023 F-150 class on the install-guide example (excludes Raptor and dual-exhaust apps on later revs). Confirm year and exhaust on AMP / RealTruck. That fitment is not this Amazon button
Drawback: bolt-on on most apps; some drilling may be required. Stow when driving. Do not order 75312-01A for a 2021–2023 class truck, or 75328-01A without confirming year and dual exhaust.
Match the AMP application SKU to year, cab, and bumper. 75312-01A covers 2015–2020 F-150 and excludes Raptor on the AMP install guide for that SKU. 75328-01A covers the 2021–2023 F-150 class and excludes Raptor and dual-exhaust apps on later revs — confirm your year on AMP / RealTruck before Shop. Other trucks have their own BedStep part numbers on AMP’s chart. Do not force an F-150 bracket onto a different bumper.
Shop by truck
75312-01A is the Shop button above. 75328-01A and the hitch step are brand chips — not Amazon. Power boards and nerf bars stay on their own pages.
75312-01A Shop is the locked /dp/ ASIN. 75328-01A is AMP / RealTruck text and brand chart only — not an Amazon listing on this page. Westin 56-10015 is a brand hitch chip, not a BedStep Shop. Power running boards — /best-power-running-boards/. Nerf bars — /best-truck-nerf-bars/.
Nerf bars or flat boards sold as BedStep. Nerf bars live on Best truck nerf bars.
Raptor or dual-exhaust apps excluded on your install guide.
A hitch drop step sold as an under-bumper BedStep. Westin 56-10015 is a 2 in receiver step. Westin does not print a load rating on that product page.
Install notes
Bolt-on on most apps; some drilling may be required. Follow the AMP sheet for your SKU. Check clearance to the spare, hitch head, and bumper sensors. After install, deploy and stow a few times empty, then with a normal load under the 300 lb rating. Re-torque after the first week.
FAQ
What is the best truck bed step?
AMP Research BedStep for a retractable under-bumper step with a 300 lb rating on AMP’s page. Match the application SKU to your truck.
How much weight does BedStep hold?
300 lb, on AMP Research’s BedStep product page.
Is BedStep the same as PowerStep?
No. PowerStep is a powered running board at the doors. BedStep is a rear bumper step for the bed.
Does it fit F-150 Raptor?
Not on the example install guides for 75312-01A and 75328-01A — those exclude Raptor. Confirm AMP’s chart for any Raptor-specific row.
Can I leave it deployed while driving?
No. Stow when driving. AMP’s install guide calls that out.
What about a hitch step instead?
Westin HDX Drop Hitch Step 56-10015 is a 2-inch receiver step, not under-bumper. Westin does not print a load rating on that product page.
Will it work with a tonneau or bed cover?
The step lives at the bumper, not in the bed rails. A cover that needs bumper clearance when open still needs a dry-fit. Confirm the cover’s rear path against a deployed and stowed step.
Does 75328-01A fit 2024–2026 F-150?
Confirm on AMP / RealTruck for your exact year. The example install guide class for 75328-01A is 2021–2023. Do not assume later years share that SKU.
Is drilling required?
AMP says bolt-on on most applications; some drilling may be required. Follow the sheet for your part number.
