UnderCover ArmorFlex AX22029 is a hard tri-folding tonneau cover for 2021-2026 Ford F-150 pickups with the 5'7" bed, and RealTruck's application for this part number explicitly includes the F-150 Raptor and, from 2022, the F-150 Lightning. That matters, because plenty of covers get built for the base 14th-generation truck and then quietly excluded from the halo trims — here the Raptor and the electric truck are named in the fitment, not left to guesswork.

The Lightning case is the interesting one. An electric F-150 spends its life with the bed exposed and the frunk doing the secure-storage job, so a rated, sealed, walk-away lid over the 5'7" box changes how usable the truck is. UnderCover rates the closed ArmorFlex at 400 lb evenly distributed, which is enough for a rooftop-tent-free load of firewood, tools, or a strapped-down cooler stack without worrying about the panels.

Construction is the ArmorFlex standard: aluminum panels wearing UnderCover's Multi-Shield textured matte-black coating, in a frame that clamps to the bed rails with no drilling on most applications. EPDM rubber seals and integrated drain tubes push water past the box, and the rear seal is dual-action, so the tailgate cycles whether the last panel is up or down. RealTruck rates the install at under an hour.

  • Aluminum panels under Multi-Shield textured matte-black coating for impact and abrasion resistance
  • EPDM rubber seals with integrated drain tubes to keep the 5'7" box dry
  • Dual-action tailgate seal — the gate works with the rear panel up or down
  • Tri-fold design lifts flush to the cab when the whole bed is needed
  • Clamp-on installation with no drilling on most applications, under an hour
  • Limited 5-year warranty against manufacturing and material defects

Fitment

UnderCover AX22029 fits 2021 through 2026 Ford F-150 pickups with the 5'7" bed, including the F-150 Raptor across the same years and the F-150 Lightning from 2022 through 2026.

Does not fit the 2021+ F-150 6'7" bed. The longer box takes sibling part AX22030 instead, so match the bed before ordering rather than the cab badge.

FAQ
Does AX22029 fit an F-150 Raptor?

Yes. RealTruck lists the F-150 Raptor in the 2021-2026 application for part AX22029 alongside the standard F-150 with the 5'7" bed.

Does AX22029 fit the F-150 Lightning?

Yes, for 2022 through 2026 Lightning trucks. The Lightning is named separately in RealTruck's application for this part number.

What is the difference between AX22029 and AX22030?

Bed length. AX22029 is cut for the 5'7" bed and AX22030 is the same ArmorFlex cover for the 6'7" (78.9") bed on the same generation of F-150.

Can I open the tailgate without unlatching the cover?

Yes. The ArmorFlex uses a dual-action tailgate seal, so the gate opens and closes with the rear panel either up or down.
