Fits GMC Sierra 1500 · 5.8 ft Bed
Bow Hinged Tonneau Cover — GMC Sierra 1500
A single, reinforced panel lifts on gas struts like a trunk lid, built for the GMC Sierra 1500’s 5.8 ft bed. Fewer moving parts than a folding cover means fewer places for a weak point to hide, and the internal ribbing distributes load the same way our other hard styles do. Mounts with bed rail clamps — no drilling required.
Shop This CoverOverview
A hinged cover is the simplest mechanism in the Bow lineup — one panel, one set of hinges, no fold seams. That simplicity is itself a structural advantage: fewer joints and moving parts means fewer places for a weak point to develop over years of daily use, which is the same underlying principle behind reinforcing the bow on our soft covers.
The panel itself uses the same internal ribbing as our other hard cover styles, spreading load across the surface instead of concentrating it at the hinge line. Gas struts lift the whole panel with one hand, giving you full bed access without the multi-panel complexity of a tri-fold cover.
Fitment note: This cover is compatible with the Sierra’s MultiPro tailgate when fully closed, but is not compatible with a CarbonPro composite bed.
Built From
Reinforced Panel Ribbing
A single aluminum-framed composite panel spans the full bed length with internal ribbing and no fold seams.
Sealed Gas Struts
Struts rated for repeated daily lifting, chosen for consistent performance over years of use.
Weather Seals
EPDM rail and tailgate seals keep the closed cover weathertight in rain and road spray.
Corrosion-Resistant Hinge Hardware
Hinge brackets anchor to the bed rail and are built to resist corrosion through repeated opening and closing.
Confirming Your GMC Sierra 1500’s Fit
Bed length has to match exactly so the hinge brackets and struts are positioned correctly. This cover is built for the GMC Sierra 1500’s 5.8 ft bed — check your bed length on the door jamb sticker or in your owner’s manual before ordering, since the GMC Sierra 1500 is also sold with 6.5 ft and 8 ft bed options depending on cab configuration.
How Installation Works
- Clean the bed rails. Wipe down the factory rail where the hinge brackets will mount.
- Mount the hinge brackets. Position and clamp the rear hinge brackets to the bed rail.
- Attach the gas struts. Connect the struts between the panel and the hinge mounts per the included instructions.
- Set the panel. Lower the panel into place and confirm it seats evenly on the seals.
- Test the lift. Open and close the panel a few times to confirm the struts hold it smoothly at any angle before your first drive.

Frequently Asked Questions
Does this fit the 2019–2024 GMC Sierra 1500?
Yes, this cover is fitted for GMC Sierra 1500 model years 2019–2024 with a 5.8 ft bed. Check your bed length on the door jamb sticker if you’re unsure which bed size your truck has.
Can I still access just part of the bed without opening the whole panel?
No — since it’s a single panel, opening the cover exposes the full bed. If you need partial access, a hard folding or retractable cover is a better fit.
Does this work with the Sierra’s MultiPro tailgate?
Yes, when the tailgate is fully closed. It is not compatible with a CarbonPro composite bed.
Can I install this by myself?
Yes. It ships with the panel and hinge hardware ready to mount, and most owners complete the install solo in under an hour.
Do the struts need any maintenance?
No regular maintenance is required, but if a strut ever feels like it’s losing lift, replacement struts are sold separately so you don’t need to replace the whole cover.
Can I stand or stack cargo on the closed cover?
Yes, within reason. The panel is rated to support distributed static weight, but avoid concentrated point loads like standing on one spot for extended periods.
