✅ OFAS VERIFIED FITMENT: 2020–2026 Chevrolet Silverado 2500/3500 HD SRW | 2020–2026 GMC Sierra 2500/3500 HD SRW | Frame-Mounted | Foot-Activated | 300 lb Load Rated
📍 Regional Best-Sellers: Engineered for Low-Desert and Rust-Belt environments.

Why Obsidian Recommended This for Your Region

Optimized for Low-Desert Utility: Low-Desert HD owners — running the Phoenix basin, the Imperial Valley, and the Coachella corridor — deal with ground temps that exceed 150°F in July and UV exposure that destroys cheap step hardware within a single season. We carry the BedStep because its high-strength aluminum construction and corrosion-resistant finish are engineered to stay dimensionally stable in sustained Low-Desert heat cycles, keeping your 300 lb load rating intact and your foot-activated mechanism deploying clean through a Southwest summer of daily HD utility use.

Built for the Rust-Belt: Rust-Belt Silverado and Sierra HD owners know that road salt, liquid brine, and freeze-thaw cycles are applied from November through March across Ohio, Michigan, Pennsylvania, and upstate New York. We’ve vetted the corrosion-resistant hardware and reinforced hinge system on this unit specifically because Rust-Belt winters don’t give cheap pivot hardware a second season on a work truck that logs 60,000 miles a year. Your hinge stays sealed, your step pad stays grippy, and your BedStep deploys in March the same way it did in August.

Is This for You? (Before You Buy)

Confirm these 3 “Truths” to ensure a 100% fit:

• [ ] Year: Do you have a 2020–2026 Chevrolet Silverado HD or GMC Sierra HD? (Pre-2020 HD trucks use different rear frame mounting geometry — those require a separate BedStep unit).
• [ ] Wheel Config: Confirm your 3500 HD is SRW (Single Rear Wheel) — Silverado 3500 HD DRW and Sierra 3500 HD DRW (Dually) have a different rear frame and bedside profile and require a separate unit.
• [ ] Rear Clearance: Are you running a stock rear bumper? Aftermarket rear bumpers, rear armor, tow sensor brackets, and trailer hitch receivers require clearance verification before ordering — measure twice.

The Driver Experience (The Obsidian Take)

Most HD bed access solutions are a milk crate or a tire step that shifts every time you use it on a truck that’s hauling 15,000 lbs. We chose the 75327-01A because AMP Research’s frame-mounted BedStep deploys with a single foot tap, holds 300 lbs without flex, and stows flush to maintain ground clearance when not in use. The reinforced hinge system and all-weather non-slip traction pad mean zero maintenance — no grease schedule, no seized pivot after a Rust-Belt winter, no step that stops working when you need it most on a job site. Expect a Silverado or Sierra HD that works as hard as the operation running it.

Obsidian DIY Notes

• Pro Tip: Measure twice before drilling — aftermarket liners, bed-extenders, tow package brackets, and trailer hitch receivers can interfere with the frame mount on this unit. Check your rear frame clearance before ordering and confirm no interference with the step travel path.
• What Else You’ll Need: Confirm your HD truck is 2020–2026 SRW before ordering. If you’re running an aftermarket rear bumper or rear armor, contact our team to verify mounting clearance before we ship.
