Common Questions
Does this fit a Dually (DRW) 3500 HD?
No. The DRW has a different rear frame and bedside profile than the SRW. This SKU is SRW only — confirm your wheel configuration before ordering.
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.
Does installation require drilling?
Most applications are bolt-on using existing mounting points. Some applications may require minor drilling, and step orientation may vary — confirm with the installation guide for your specific configuration.
The Obsidian Take
The BedStep (75327-01A) is for the 2020–2024 Silverado or Sierra 2500/3500 HD SRW 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.
One mandatory check before ordering: confirm SRW, not DRW. The dually's rear frame and bedside geometry are different enough that this BedStep will not mount correctly on a dually-equipped 3500 HD.
Non-Returnable Notice: Once installed, this unit is non-returnable per AMP Research policy. Confirm wheel configuration (SRW vs. DRW) before ordering.
