XTR3 Bed Rack for Retrax XR Cover - Chevrolet Silverado & GMC Sierra 2

Get your rig dialed in just right with the most modular bed rack on the market today — this one is purpose-built to fit Retrax XR tonneau covers with T-slot rails (cover sold separately — this listing is the rack). If you run a Retrax XR cover 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 — no drilling, no compromise.

The Silverado 2500HD/3500HD and its GMC Sierra HD twin are heavy-duty tow rigs built to work hard — fifth-wheel haulers, jobsite trucks, and basecamp tow vehicles. As a truck bed ladder rack it carries lumber, conduit, pipe, and ladders for the trades; as an overland platform it hauls your rooftop tent, fuel, water, and recovery gear above a loaded bed. Run it as a Silverado HD ladder rack, a cargo rack for heavy work hauls, or a full overland build — and keep your Retrax cover working through all of it.

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 Silverado or Sierra HD? This is your exact-fit rack.

Why XTR3 is different

The XTR3 is the newest variant of our bed rack. It divides the rack into 4 equal quadrants, giving you 4 independently adjustable side braces for true modularity. It comes with 6 uprights, 4 side braces, 3 top crossbars, and 4 top support braces.

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 independently adjustable quadrants — fully modular for rooftop tents, awnings, traction boards, fuel and water, jobsite tools, ladders, and pipe.
Tonneau-friendly by design — built around your Retrax XR cover, not in spite of it.

As an added bonus, your XTR3 Bed Rack includes some of our most popular accessories and mounting hardware so you can start mounting brackets and gear to your new rack right away. Check them out below.
