Overland and camping gear for Chevy Silverado HD and GMC Sierra HD trucks, 2500 and 3500, gathered on one page: racks and the XO.SKLTN shell from our Wichita shop, a drawer system and tie-down hardware for the box, a tailgate panel, and the accessories that mount to an XTR rack. To compare the racks alone, with heights, ratings and prices side by side, go to Silverado and Sierra 2500HD / 3500HD bed racks.
Building out a Silverado or Sierra HD
-
Rack or shell first. For an open box, the XTR1 comes at 17" or 24", or at a custom height up to 26". If a Retrax XR covers the bed, the XTR3 for Retrax XR adds a third crossbar and a middle pair of uprights; the XTR3 is also the one rack we make for the 8-ft HD box. XBRS bed bars ride 6" or 8" above the rails, and the XO.SKLTN turns the standard box into a lockable aluminum shell.
-
Tent up top, or gear under a roof. On a 2020+ HD, a 24" rack sits 2" over the cab roof, so a rooftop tent can stretch forward over the cab without a riser. Our Rooftop Tent Brackets come four to a kit for $49.90, or eight for $98. To keep the bed enclosed instead, order the XO.SKLTN as Stage 2A or 2B with its topper panels, or add the XO.SKLTN Topper Panel Add-On Kit for HD trucks down the road.
-
Organize the box. Because the racks bolt to the bed rails, the floor is free for a DECKED drawer system, sized for the 6.5-ft and 8-ft HD boxes from 1999 on. On 2020+ HD trucks, Integral's Swivel Strap Mounts bolt to the factory tie-down anchors and reel out a 1" x 9' strap rated for a 400 lb working load, and the Integral bulkhead plate holds Packout cases against the front wall. Running a Retrax? Skip the bulkhead plate and the front strap mounts, because the cover's canister is in the way; the rear strap mounts work under any cover.
-
Bolt-ons for the rack. Slide-out trays, AXS side gates, MOLLE plates, a recovery board mount and a Rotopax plate all lock into the T-slots on an XTR rack. For shade, the XTR Awning Upright Kit lifts an awning anywhere from 8" to 18" up and holds 60 lb, rising to 100 lb with the support braces for a heavy 270° awning. It's made for XTR1 and XTR3 racks; XBRS bars and the XO.SKLTN can't take it.
-
A work surface at the tailgate. The TrailGate panel lays 1/8" aluminum over the factory tailgate for a camp kitchen counter or a spot to kneel. HD trucks take the 2500/3500 version, in Standard or Multi-Flex / Multi-Pro. It's built in Wichita and starts at $299.
HD build questions
Should my HD get an XTR rack or the XO.SKLTN?
An XTR rack leaves the sides of the bed open, carries a rooftop tent or long stock, and with a Retrax XR it covers the 8-ft box too. The XO.SKLTN fits the standard box and closes your gear in behind locking doors on both sides and at the rear. Our post comparing bed racks, overland toppers and fiberglass toppers walks through the differences.
What can I build on an 8-ft HD box?
With a Retrax XR on the truck, the XTR3 for Retrax XR or the XTR3 Custom Height (from 10" to 26"). Below the rack, DECKED makes its drawer system in an 8-ft length, and since the TrailGate panel is matched to the tailgate, box length doesn't matter for it. For an open 8-ft bed, email us and we'll tell you what works.
How heavy can the whole setup get?
Count it twice. What sits on the rack has to stay inside the rack's rating (for the XTR3, 500 lb on trails, 850 lb on the highway and 1,750 lb parked, spread evenly). Then everything, from the rack and tent to drawers, water, tools and passengers, has to fit within the payload on your door-jamb sticker. DECKED drawers alone are about 200 lb. Our overlanding payload guide has a worked example.
Is this the right page for a Silverado 1500?
No. The 1500 uses its own racks and parts: see the Silverado and Sierra 1500 overland build.
Can I try out a layout before buying?
Yes. Put a rack, plates, gates and trays together in our 3D bed rack builder, then order straight from it.
