The UnderCover ArmorFlex AX12026 is a hard folding truck bed tonneau for the 2020-2026 Chevrolet Silverado 2500/3500HD and GMC Sierra 2500/3500HD with the 8' (98.2") long bed. Heavy-duty panels are finished with a LINE-X specialty automotive coating for advanced dent and scuff resistance, and the cover folds forward for full bed access while clamping down flat for a secure, weather-tight deck.

Fitment: Fits the 2020-2026 Silverado 2500/3500HD and Sierra 2500/3500HD with the 8' (98.2") long bed. It does not fit the 6'10" standard bed, which uses the sibling AX12024, and does not fit the light-duty 1500 trucks.

What's included: Pre-assembled ArmorFlex folding cover with LINE-X-coated panels, clamp-on mounting hardware, and a dual-action tailgate seal for universal tailgate operation. No drilling required.
