Dodge Ram 2500/3500 HD Bed Rack for Retrax XR Covers - Tapered Bed | 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 Ram 2500/3500 HD 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.

Bed Geometry Note: Dodge Ram trucks come in both straight and tapered bed configurations. This listing is optimized for the tapered bed variant. Please verify your bed measurement and rail spacing before ordering to ensure proper fit.

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 Ram 2500/3500 HD 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 Dodge Ram 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 Ram 2500/3500 HD? 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 Ram?

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 Ram?

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.

How do I know if I need the Straight Bed or Tapered Bed version?

Dodge Ram trucks come with either a straight or tapered bed, depending on the model year and factory configuration. This listing is for the tapered bed. To find out, measure from the inside edge of the bed rail, measure both the front width and rear width of your bed. If the measurements are different, you have a tapered bed. If they are the same, you have a straight bed.
