| Aftermarket rear bumpers, rear armor, or tow sensor brackets | May interfere with frame mount or step travel path — verify clearance before ordering |
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.
I have an F-450 — will this work?
Not if your F-450 has the vibration damper installed. This is a confirmed hardware conflict, not a general fitment caution. Check for this component before ordering, or contact us to verify.
Does installation require drilling?
No. This BedStep installs using existing factory mounting holes.
The Obsidian Take
The BedStep (75313-01A) is for the 2017–2022 Super Duty owner who wants reliable foot-activated bed access at the rear bumper without giving up tailgate or towing functionality. Die-cast aluminum, glass-reinforced step pad, 300-lb rating, 3-year warranty — simple, mechanical, no electronics.
This is not the right product if your F-450 has a vibration damper installed — confirm before ordering. This is a confirmed hardware incompatibility, not a soft caution.
Non-Returnable Notice: Once installed, this unit is non-returnable per AMP Research policy. Confirm fitment and F-450 vibration damper status before ordering.
