Collection: 2020-2026 GMC Sierra 3500HD Roof Racks & Crossbars

Roof racks and crossbars confirmed to fit the 2020-2026 GMC Sierra 3500HD, both Crew Cab and Double Cab. Stocking options from Rhino-Rack, Yakima, and Prinsu, including bare-roof clamp mounts, raised-rail crossbars, and full-coverage cab racks rated for kayaks, rooftop tents, and Tred boards.

Will a rooftop tent fit a Sierra 3500HD cab rack? Yes. The racks we list here carry 600-800 lb static loads, well above the 250-400 lb a typical hardshell or softshell RTT requires when parked and occupied.

Verified fitment on every SKU, no guesswork at checkout.
