Buying guide
AMP Research BedStep kicks out from under the rear bumper, holds 300 lb, and tucks back up when you’re done. Match the part to your truck’s year first.

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 part.
Skip this guide 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 brand search below). Skip Raptor and dual-exhaust apps excluded on the install guide for your year.
300 lb load rating. Aluminum alloy frame. Glass-reinforced non-slip pad. Kick to deploy and kick to stow. 3-year limited warranty. Example: 75312-01A (2015–2020 F-150, excl. Raptor). 75328-01A (2021–2023 F-150 class — confirm year, exhaust on AMP, and RealTruck) is not this Amazon pick.
Westin HDX Drop Hitch Step 56-10015 — universal 2 in receiver hitch step, not an under-bumper BedStep. Westin for that part does not list a step load rating. It is not a 300 lb AMP BedStep substitute.
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.
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.
AMP lists 300 lb for the BedStep. That is AMP’s listed BedStep load rating. Westin 56-10015 does not list a load rating on its site, so that figure stays blank here.
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.
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 a hanging step is not left in a parking lot.
AMP’s under-bumper mount is meant to stay clear of an open tailgate and of towing on the maker 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 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.
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 brand search here. It is not retractable under the bumper, and Westin doesn’t list a pound rating for it. For a dedicated under-bumper pad with a listed 300 lb line, stay on AMP BedStep.
For a kick-out platform at the rear bumper that stows when you are done.
Catch: bolt-on on most apps; some drilling may be required. Stow when driving. Skip 75312-01A for a 2021–2023 class truck, and skip 75328-01A without confirming year and dual exhaust.
Westin 56-10015 is a hitch brand search, not a second BedStep. Load left blank where Westin does not list one. No prices here.

| Example F-150 | 75312-01A (2015–2020, excl. Raptor); 75328-01A (2021–2023 class — confirm) | Universal 2 in receiver |

Match the AMP application part to year, cab, and bumper. 75312-01A covers 2015–2020 F-150 and excludes Raptor on the AMP install guide for that part. 75328-01A covers the 2021–2023 F-150 class and excludes Raptor and dual-exhaust apps on later revs — confirm your year on AMP or RealTruck before you buy. Other trucks have their own BedStep part numbers on AMP’s chart. An F-150 bracket will not fit a different bumper.
75312-01A is the pick above. 75328-01A and the hitch step are brand-site paths — not Amazon picks. Power boards and nerf bars stay on their own guides.
75312-01A is the Amazon BedStep example. 75328-01A is AMP and RealTruck text and brand-site text only — not linked as an Amazon product here. Westin 56-10015 is a hitch-step brand search, not an under-bumper BedStep. Power running boards. our power running boards guide. Nerf bars. our truck nerf bars guide.
AMP PowerStep running boards sold as a bed step. Those live on Best power running boards.
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 doesn’t list a load rating for it.
Bolt-on on most apps; some drilling may be required. Follow the AMP sheet for your part. 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.
AMP Research BedStep for a retractable under-bumper step with a 300 lb rating on AMP. Match the application part to your truck.
300 lb, per AMP Research for the BedStep.
No. PowerStep is a powered running board at the doors. BedStep is a rear bumper step for the bed.
Not on the example install guides for 75312-01A and 75328-01A — those exclude Raptor. Confirm AMP’s chart for any Raptor-specific fitment.
No. Stow when driving. AMP’s install guide calls that out.
Westin HDX Drop Hitch Step 56-10015 is a 2-inch receiver step, not under-bumper. Westin doesn’t list a load rating for it.
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.
Confirm on AMP or RealTruck for your exact year. The example install guide class for 75328-01A is 2021–2023. Later years may not share that part — confirm the maker’s fit chart.
AMP says bolt-on on most applications; some drilling may be required. Follow the sheet for your part number.
