Chevy Colorado / GMC Canyon Bed Rack for Retrax XR Covers | XTR1

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 Chevy Colorado or GMC Canyon 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 Colorado/Canyon 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 Chevy Colorado 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 Colorado or Canyon? 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 Colorado/Canyon?

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, both of which are built at a 13.3° angle to match your topper’s sidewalls.

Does this require drilling into my Colorado/Canyon?

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.
