📍 Regional Best-Sellers: Engineered for Tropical and High-Altitude environments.

Why Obsidian Recommended This for Your Region

Optimized for Tropical Conditions: Tropical climate Super Duty DRW owners — running South Florida, the Gulf Coast, and Hawaii — deal with year-round humidity, salt air, and UV exposure that destroys cheap step hardware within a single season. We carry the BedStep2 Dually Kit because its high-strength aluminum construction and corrosion-resistant finish are engineered to resist Tropical moisture infiltration at the pivot, keeping your 300 lb load rating intact and your foot-activated mechanism deploying clean through 365 days of heat and humidity on a work platform that can’t afford downtime.

Built for High-Altitude Conditions: High-Altitude Super Duty DRW owners — running Colorado ranches, Rocky Mountain job sites, and Sierra Nevada work routes — deal with UV exposure, freeze-thaw cycles, and temperature swings that destroy cheap step hardware fast. We’ve vetted the reinforced hinge system and corrosion-resistant hardware on this unit specifically because High-Altitude conditions demand a step that deploys reliably when the temperature drops 50 degrees overnight and ice has been sitting on the step pad since 3 AM on a job site that starts at 6.

Is This for You? (Before You Buy)

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

• [ ] Wheel Config: Do you have a DRW (Dual Rear Wheel / Dually) F-350 or F-450? (This kit is DRW-specific — SRW models use a different bedside mounting geometry and require a separate unit. F-250 is SRW-only and is not compatible).
• [ ] Year: Confirm your Super Duty is 2017–2022 (P558 platform). The 2023–2026 Super Duty is the new P702 generation with a revised DRW bedside profile — it requires a separate unit.
• [ ] Bedside Clearance: Are you running stock fender flares and bedside panels? Aftermarket fender flares, bedside armor, and fuel tank skid plates require clearance verification before ordering — measure twice.

The Driver Experience (The Obsidian Take)

Most DRW Super Duty bed access solutions are a wheel well step that puts you in the wrong position or a ladder that takes 30 seconds to deploy on a truck that’s hauling 20,000 lbs and needs to keep moving. We chose the 75413-01A because AMP Research’s DRW-specific side-mounted BedStep2 deploys with a single foot tap just ahead of the dual rear wheels, 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 High-Altitude winter, no step that stops working when you need it most. Expect a P558 DRW that works as hard as the operation running it.

Obsidian DIY Notes

• Pro Tip: Measure twice before drilling — aftermarket fender flares, bedside armor, and fuel tank skid plates can interfere with the DRW side mount on this unit. Confirm your bedside clearance before ordering and verify no interference with the step travel path around the dual rear wheel housing.
• What Else You’ll Need: Confirm your Super Duty is a 2017–2022 P558 DRW — not SRW, not 2023+ P702 — before ordering. If you’re running aftermarket bedside modifications, contact our team to verify mounting clearance before we ship.
