Bed racks for Chevy Silverado 2500HD and 3500HD and GMC Sierra 2500HD and 3500HD trucks, 2001 to today. The Chevy and GMC versions of each generation use the same box, so any rack on this page fits either badge. Your cover narrows the choice: an open bed or soft tonneau takes the four-upright XTR1, a Retrax XR takes the XTR1 or the six-upright XTR3 (the one rack here offered for the 8-ft box), and a soft topper takes its own angled XTR1. Our XTR racks are built to order, to your height requirements, with T-slot profile construction on every bar, mount without drilling, and come out of our shop in Wichita, Kansas.

Long bed or Retrax XR? Look at the XTR3
On Silverado and Sierra HD trucks, as on the 1500, the six-upright XTR3 is built for trucks running a Retrax XR, where it bolts to the cover's own T-slot rails. It's also the only rack on this page made for the 8-ft box. An open HD bed gets the four-upright XTR1, which we build for the standard box. Have an 8-ft bed and no Retrax? Email us before you order.
Finding your year and box on the menus
Our HD rack menus follow GM's four body styles: 2001–2007, 2007.5–2014, 2015–2019 and 2020 on. A 2007 built on the older body (sold as the Classic) goes with 2001–2007, and a redesigned 2007 goes with 2007.5–2014; the XO.SKLTN menu lists that second body as 2008–2014.
The standard HD box measures 6'6" through 2019 and 6'9" from 2020. Rack menus call it "Regular Bed" (6.5 ft or 6.75 ft), and the XO.SKLTN menu calls it "Medium Bed". The 8-ft box appears only on the two XTR3 listings built for Retrax covers.
17", 24" and 25" against a 2020+ cab
On the current body (the 2020+ menu option), the cab roof peaks 22" above the top of the bed rail and the back edge of the cab sits at 20". A 24" cab-height rack therefore clears the roof by 2", more than the 1" we ask for when a rooftop tent reaches over the cab. The 17" mid-height rack stays 5" under the roof and 3" under the back edge, and the soft topper rack is built at 25".
On a 2001–2019 HD, or with a roof rack, cab lights or a tall antenna, measure from the bed rail to the highest point and add at least 1". Custom Height racks run up to 26", and a universal XTR Tent Riser Kit is on the way.
Reading the load ratings
Each rack carries three numbers. The off-road figure is for trail driving, the on-road figure is for highway miles with ladders or cargo up top, and the static figure applies once the truck stops, which is what a rooftop tent with people inside is measured against. All three assume the load is spread across the crossbars. However much payload your HD has, the rack's rating still caps what goes on top, and the rack plus its load counts against that payload.
Running a cover under the rack
-
Soft or roll-up tonneau: XTR1 racks ride on Chevy-specific Wide Width brackets that sit outside the bed rails and lift the rack 3" above them, so most soft and roll-up covers keep opening and closing. Tri-folds fit but can't fold fully open beneath the rack. The XBRS Universal (Wide) Mount gives the same 3".
-
Retrax XR: choose the XTR1 or XTR3 for Retrax XR, or XBRS on its Retrax XR mount. All of them fasten to the cover's rails.
-
Softopper, Fas-Top or Bestop: the XTR1 Soft Topper rack.
-
Roll-N-Lock XT, Pace Edwards UltraGroove or other covers with their own T-slot rails: tell us the cover model before ordering; fit comes down to that cover's rail dimensions.

Silverado HD and Sierra HD bed rack questions
Do 2500HD and 3500HD trucks take the same rack?
Yes. The listings cover both, along with the matching Sierra HD models, so you only pick the year range, box and height.
Is there a rack for an 8-ft Silverado or Sierra HD?
Yes, if the truck has a Retrax XR: the XTR3 for Retrax XR and the XTR3 Custom Height both come in an 8-ft version. For an open 8-ft bed, email support@xtrusion-overland.com and we'll suggest what will work.
Can a rooftop tent sit over the cab of my HD?
On a 2020+ truck, yes: the 24" rack is already 2" above the roof. Bolt the tent down with our stainless Rooftop Tent Brackets, and add up the tent, its occupants and any other gear on top against the static rating.
Can I haul ladders and lumber on it?
Yes. Long stock rides on the crossbars and can overhang the cab or the tailgate. Strap it down and keep it under 850 lb (XTR racks) or 800 lb (XBRS) on pavement.
Will I need to drill my bed rails?
No. XTR racks bolt to the bed rails with the brackets supplied, Retrax versions fasten to the cover's rails, and XBRS installs without drilling too.
What if I want a different height later?
Order the HD Alternate Height and Conversion Kit in the new height, plus side and top braces and reinforcement plates to suit. XBRS bars, for their part, can grow into a full XTR1.
