Bed racks for the 1999-and-newer Chevy Silverado 1500 and GMC Sierra 1500. The two trucks share their beds, so every rack on this page fits both. What covers your bed decides the rack: the four-upright XTR1 for an open bed or a soft tonneau, the six-upright XTR3 when a Retrax XR is on the truck, XBRS bars for a low profile, or the XO.SKLTN if you want the bed to become a lockable topper. Each XTR rack is built to order, to your height requirements, in T-slot profile construction, and every one is designed and built in Wichita, Kansas.

Why the only Silverado XTR3 rides on a Retrax
On these trucks, an XTR3 without a Retrax XR would have to bolt to the stake pockets, which we never use as a rack mount. With a Retrax XR in place, the XTR3 bolts to the cover's own T-slot rails instead. So an open bed or a soft tonneau gets the four-upright XTR1, and the six-upright XTR3 is sold for Retrax XR trucks only.
Which year option is my truck?
The rack menus split the Silverado and Sierra 1500 into four body styles: 1999–2007 Classic, 2007.5–2013, 2014–2018 and 2019+. Two model years came in both an old and a new body, so check those first:
-
2007: a 2007 Classic belongs with 1999–2007, and the redesigned 2007 belongs with 2007.5–2013.
-
2019: the 2019 Silverado LD and Sierra 1500 Limited are the older body and belong with 2014–2018. Every other 2019 is 2019+.
Next, the box. The 5'8" short box takes a 61" rack and the 6'6" standard box takes a 71" rack; the rack menus call that one "Regular Bed", and the soft topper and XO.SKLTN menus call it "Medium Bed". We don't build XTR racks for the 8-ft box, so email us about a long-bed truck. The bed is tapered and the rack is straight, and the Chevy-specific brackets take up the difference.
Where 17" and 23" sit against the cab
Measured from the top of the bed rail, the highest point of the cab roof is 22" on 2008–2018 and 2019+ trucks, and the back edge of a 2019+ cab is 20". That puts a 23" cab-height rack 1" over the roof, the clearance we recommend for a tent that extends forward over the cab, so no custom height is needed. A 17" mid-height rack sits 5" under the roof on a 2008–2018 truck and 3" under the back of a 2019+ cab.
On a 1999–2007 truck, or with cab marker lights, an antenna or a roof rack, measure to the highest point and plan at least 1" above it. Custom Height racks go up to 26", and a universal XTR Tent Riser Kit is coming soon.
What the three ratings mean
The first number is what the rack can carry over rough trails, the second is for pavement, and the third is the load once the truck is parked, which is the one that counts for a rooftop tent with people asleep in it. All three assume the weight is spread across the rack. Whatever rides on the rack, plus the rack itself, also counts against your truck's payload, listed on the label inside the driver's door. Our overlanding payload guide walks through how quickly a tent, water and passengers add up.
Tonneau covers, Retrax covers and soft toppers
-
Soft or roll-up tonneau: XTR1 racks ship on Chevy-specific Wide Width brackets that reach out past the bed rails and hold the rack 3" above them, leaving room for most soft and roll-up covers to open and close underneath. A tri-fold fits, but it won't fold all the way open under the rack. XBRS on the Universal Mount also leaves 3" of clearance.
-
Retrax XR: the Retrax builds of the XTR1 and XTR3 attach to the cover's T-slot rails, and XBRS offers a Retrax XR mount. Still shopping for the cover? See Silverado and Sierra 1500 bed covers.
-
Softopper, Fas-Top or Bestop on a 2007-or-newer truck: the XTR1 Soft Topper rack, with its uprights angled at 13.3° so they miss the fabric.
-
A cover with built-in T-slot rails (Roll-N-Lock XT, Pace Edwards UltraGroove and similar): email us the cover model before you order, since fit depends on that cover's rail measurements.
Silverado and Sierra 1500 bed rack questions
Will a Silverado bed rack fit my GMC Sierra 1500?
Yes. Every rack here is listed for both trucks because the Silverado 1500 and Sierra 1500 share their beds. Choose the same year range and box either way.
Is there a rack for the 8-ft long bed?
Not an XTR rack: we build them for the 5'8" and 6'6" boxes. Email support@xtrusion-overland.com with your truck and we'll tell you what fits a long bed.
Can a rooftop tent hang over the cab?
On 2008-and-newer trucks, yes, at the standard 23" height, which clears the roof by the 1" we recommend. Our stainless Rooftop Tent Brackets hold it to the crossbars. Count the tent, whoever sleeps in it and everything else up top against the rack's parked rating. Our Silverado 1500 rooftop tent guide covers which tents fit the 61" and 71" racks and how tall the truck ends up with one on top.
Will it work as a ladder or lumber rack?
Yes. Ladders, lumber and conduit lie across the crossbars and may stick out over the cab or beyond the tailgate. Tie the load down and keep it within 850 lb on an XTR rack, or 800 lb on XBRS, while you drive on the road.
Is any drilling involved?
No. XTR racks attach to the bed rails with the brackets and hardware that ship with them, Retrax builds attach to the cover's rails, and XBRS goes on without drilling as well.
Can I start with bed bars, or change the height later?
Both. XBRS bars convert into a full XTR1 rack when you're ready, and the XBRS listing names the parts. Moving an XTR rack to a new height takes the Alternate Height and Conversion Kit for the Silverado and Sierra 1500, together with new side and top braces and reinforcement plates sized for that height.
