Ford F-250/F-350 Super Duty Bed Rack for Retrax XR Covers | XTR3

This is the XTR3 Bed Rack for Retrax XR Covers — purpose-built to mount directly to the Retrax XR tonneau cover’s integrated T-slot rails (cover sold separately — this listing is the rack). If you run a Retrax XR on your Ford F-250/F-350 Super Duty and thought a bed rack meant giving up your tonneau, the XTR3 Retrax XR Build mounts directly to the cover’s own T-slot rails, so you keep your weather-sealed, locking bed and gain a full overland & utility rack on top with six uprights and extra load-bearing capacity — no drilling, no compromise.

What it does

Bolts directly to your Retrax XR cover’s T-slot rails using the included bedrail brackets, which mount directly to the cover’s rails without drilling any holes. It turns your F-250/F-350 Super Duty bed into a fully modular cargo platform: carry a rooftop tent, awning, recovery gear, fuel, and water on top, while keeping the bed underneath locked and weather-sealed. Works as a Ford F-250/F-350 Super Duty ladder rack, a cargo rack for lumber and conduit, or a no-nonsense overland basecamp — built from solid T-slot aluminum, not flimsy sheet metal.

Built for the Retrax XR Cover

This is not a universal bracket forced to fit. The XTR3 Retrax XR Build ships pre-configured for the Retrax XR’s integrated T-slot rail system — the bedrail brackets connect your uprights straight to the cover, so the rack and the tonneau work as one. Already running a Retrax XR on your Ford F-250/F-350 Super Duty? This is your exact-fit rack.

Why XTR3 is different

The XTR3 is our six-upright bed rack, designed to provide extra load-bearing capacity compared to traditional four-upright systems. The center upright on each side rail gives you a solid middle point for spanning long items like lumber or conduit, and an extra anchor point for heavier gear. Its open design provides excellent side access, outstanding accessory compatibility, and a clean layout that’s equally at home on work trucks, overland builds, and daily drivers. It comes with 6 uprights (one in each corner + one center upright on each side rail), 2 side braces, 2 top crossbars, and 2 top support braces. Fewer moving parts, lighter weight, and a clean, traditional look that ages well under trail dust and jobsite grime.

• Solid extruded aluminum — the strongest, lightest, most modular material on the market, with no rust and no sacrifice in features.
• T-slot on every linear surface — near-infinite mounting points; mount anything in any position and reconfigure in minutes.
• 6 uprights (one in each corner + center uprights) — extra load-bearing capacity for heavier gear, longer spans, and extra mounting points for accessories.
• Tonneau-friendly by design — built around your Retrax XR cover, not in spite of it.

Choose XTR3 if you...

Need more load-bearing capacity. It is the starting point for a modular truck system. Start with the bed rack, then add accessories as your needs change. Depending on your setup, the XTR3 can work with MOLLE panels, AXS Gates, slide-out storage, recovery gear mounts, lighting, water storage, and other rack-mounted accessories.

Because the rack is built around T-slot extrusion, you can continue adapting the layout instead of replacing the entire system as your build grows.

Frequently Asked Questions

Will this rack work with a Softopper, FasTop, or Bestop on my Ford F-250/F-350?

No. This rack is designed to mount to your Retrax XR tonneau cover’s T-slot rails. If you run a canvas-style soft topper, look at our XTR1 Soft Topper Bed Rack or XTR3 Soft Topper Bed Rack instead.

Does this require drilling into my Ford F-250/F-350?

No. The rack mounts directly to the Retrax XR cover’s T-slot rails using the included bedrail brackets. No permanent modifications to your truck or cover, and no compromising your factory finish.
