Collection: 2020-2026 GMC Sierra 3500HD Hard Folding Bed Covers

Hard folding bed covers fitted for the 2020-2026 GMC Sierra 3500HD. Covers both the 6'9" standard and 8' long bed configurations, with options from BAKFlip, Extang Solid Fold, and UnderCover Armor Flex stocked for SLE, SLT, AT4, and Denali trims.

Will a hard folding cover work with the MultiPro tailgate? Yes. Every cover here clears the MultiPro tailgate's inner gate function, so you can still drop the load-stop without removing or unlatching the cover.

Verified fitment on every listing -- if it shows here, it fits your Sierra 3500HD.
