This is the XTR1 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 Toyota Tundra and thought a bed rack meant giving up your tonneau, the XTR1 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 — 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 Toyota Tundra 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 Toyota Tundra 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 XTR1 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 Toyota Tundra? This is your exact-fit rack.
Why XTR1 is different
The XTR1 is our original four-upright bed rack and the foundation that established the Xtrusion Overland rack system. 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 4 uprights (one in each corner), 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.
- 4 uprights (one in each corner) — classic, proven load distribution for tents, awnings, recovery gear, and commercial gear.
- Tonneau-friendly by design — built around your Retrax XR cover, not in spite of it.
Choose XTR1 if you...
Want more than just a rack. 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 XTR1 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 Tundra?
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 Tundra?
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.
