Fitment, Shipping & Product Support
The AMP Research BedStep (SKU 75303-01A) is the frame-mounted, foot-activated retractable bumper step for the 1999–2016 Ford F-250, F-350, and F-450 Super Duty. Die-cast aluminum alloy linkage, black-anodized with PTFE powder coating for corrosion resistance. Mounts under the rear bumper — works with an open tailgate or while towing. Supports up to 300 lbs. Non-slip step pad. 3-year / 26,000-mile limited warranty. 11.0 lbs.
This is the 1999–2016 platform only. The 2017+ Super Duty uses a different rear frame geometry and requires a separate BedStep unit.

What Is and Is NOT Included
| Item | Included |

BedStep vs. BedStep2 — Choose the Right Mount Position
| Product | Mount Position | Best For |
|---|---|---|
| BedStep — 75303-01A (this listing) | Under the rear bumper | Bed access at the rear of the truck — works with open tailgate or while towing |
| BedStep2 | Just behind the cab, forward of the rear wheel | Access to toolboxes and equipment mounted mid-bed — independent of tailgate position |
Choose based on where you need step access on the truck. The rear bumper-mounted BedStep is the correct choice when tailgate or towing access matters most.

Critical Compatibility
| Configuration | Notes |
|---|---|
| 2017+ Super Duty | Does not fit — revised rear frame geometry requires a different BedStep SKU. Confirm correct part number before ordering. |
| Aftermarket rear bumpers, rear armor, or tow sensor brackets | May interfere with frame mount or step travel path — verify clearance before ordering |
| F-450 chassis cab configurations | Confirm rear bumper configuration and body style before ordering |
| Step pad contacting bumper | Provided spacers resolve this on applicable models — confirm fit during install |
| Tab clearance | Manufacturer notes the mounting tab may require modification for proper clearance on some vehicles — not universal across all configurations |
Common Questions
Will this work with my tailgate open or while towing?
Yes. The BedStep frame-mounts under the rear bumper specifically so it functions normally with the tailgate open or with a trailer hitched. This is the core advantage of the rear bumper mount position over alternatives that require tailgate clearance.
Does this fit my 2017 Super Duty?
No. Ford revised the Super Duty rear frame geometry starting in 2017. This BedStep (75303-01A) is built for the 1999–2016 frame only. A 2017+ Super Duty requires a different, platform-specific BedStep part number.
I have an aftermarket rear bumper — will this still mount?
Possibly not without modification. Aftermarket rear bumpers, rear armor, and tow sensor brackets can interfere with the frame mount or the step's travel path. Measure clearance before ordering, or confirm fitment with us before purchase.
Does installation require any vehicle modification?
Standard installation uses the provided spacers and hardware without modification. However, AMP Research notes the mounting tab may require modification for proper clearance on some vehicles — not all. Professional installation is recommended for optimal bracket alignment.
The Obsidian Take
The BedStep (75303-01A) is for the 1999–2016 Super Duty owner who wants reliable foot-activated bed access at the rear bumper without giving up tailgate or towing functionality. Die-cast aluminum construction, stainless pivot pins, 300-lb rating, and a 3-year/26,000-mile warranty back a simple mechanical solution — no motors, no electronics, nothing to fail in cold weather.
This is not the right product if you're running an aftermarket rear bumper without first confirming clearance, or if your Super Duty is a 2017 or newer model. Confirm your frame generation and rear bumper configuration before ordering — both determine whether this BedStep mounts cleanly.
Non-Returnable Notice: Once installed, this unit is non-returnable per AMP Research policy. Confirm fitment, rear bumper compatibility, and model year before ordering.
