BAKFlip F1 Hard Folding Tonneau Cover for 2019-2026 Chevrolet Silverado 1500 / GMC Sierra 1500 (6'6" Bed)

The 6'6" standard box is what you order when the 5'8" is not quite enough truck, usually on a double cab, and it is the bed that actually gets used for work on a T1 Silverado 1500 or Sierra 1500. That means the cover has to survive being loaded around rather than just looking good in a driveway. The F1's fiber-reinforced top skins over a high-density foam core take an impact without denting, the aluminum side rails give the panels something solid to latch into instead of a soft edge, and the closed cover carries 400 lb evenly distributed. It goes on with hand tools in under an hour, no drilling, and comes back off just as cleanly. Steel bed only, not CarbonPro.

What's Included:

• BAKFlip F1 hard folding tonneau cover, pre-assembled
• Two clamp-on aluminum side rails
• Clamp set and hardware kit
• Integrated buckle straps and prop rods
• BAKFlip hard-folding install guide

Features

FRP Top Skins Over a High-Density Foam Core
The F1 is built in layers. Heavy-duty fiber-reinforced plastic top skins take the hits, a rigid high-density foam core carries the load, and powder-coated aluminum bottom skins close the sandwich. That construction is what lets the closed cover hold 400 lb evenly distributed and shrug off dropped gear, branches, and hail that would dent a single-layer panel.

Ultra-Low-Profile, Nearly Flush With Your Bed Rails
This is the low-profile one. The panels sit nearly flush with the top of your bed rails, so from the side the cover almost disappears and the truck keeps its factory line. The textured gloss-black finish reads as trim, not as an add-on bolted to the bed.

Panels That Latch Themselves Into the Side Rails
Close the cover and each panel automatically latches into the aluminum side rails. There is no loose edge for someone to get a bar under, and no separate locking step to forget. To open, reach under the rear panel and pull the release cable.

Wrap-Around Seals and a Real Drainage System
Premium EPDM rubber perimeter seals close the gap between the cover and the bed rails, and rounded hinges shed water instead of trapping it. Most applications add a dual-action tailgate seal at the back edge. Anything that gets past the seals runs down the rails and out through the drain tubes at the front of the bed. Like every folding cover this is water-resistant rather than submersible.

Two Open Positions, and the Brake Light Never Disappears
Drop the tailgate, release the rear latches, and fold the F1 forward to expose two thirds of the bed, then cinch the integrated buckle straps and drive. Need the whole bed? Fold it once more against the cab and set the integrated prop rods. Rubber bumpers protect the cab, and your third brake light stays visible in every position.

Bolt-On Install in Under an Hour, Backed Five Years
The F1 clamps to your factory bed rails with the included hardware. No cutting, no trimming, no drilling into the truck, and most owners are done inside an hour with basic hand tools. It is assembled in Missouri and carries a 5-year limited warranty with US-based product support.
