The best BAKFlip truck bed cover depends on your truck’s make, model, and exact bed length. These five options include hard-folding BAKFlip MX4 covers for Ford and GM trucks, plus a retractable hard cover for select Silverado and Sierra 1500 models. The F-150 MX4 is best for newer Ford half-ton trucks; the Silverado/Sierra MX4 fits specified 1500 models; and the heavy-duty options serve select Ford Super Duty and GM 2500/3500 trucks.

| BAKFlip MX4, GM HD | 2020–2026 GM 2500/3500 | 6′ 10″ |

BAKFlip MX4 for Ford F-150
This hard-folding MX4 is listed for 2021–2026 Ford F-150 models, including Raptor and Lightning, with a 5-foot-7-inch bed measuring 67.1 inches. Its updated design includes a patented, upgraded auto-latch locking system that the product description says is designed to help secure cargo.
Best for: F-150 owners who want a hard-folding cover and whose truck matches the listed year and bed length. It was selected for its specific newer F-150 fitment and auto-latch feature.
Check before buying: The listing’s fitment is limited to the specified 5-foot-7-inch bed. Confirm your truck’s model year, bed size, and trim fitment rather than relying on the F-150 name alone.
BAKFlip MX4 for Silverado and Sierra 1500
This MX4 is listed for 2019–2026 Chevy Silverado and GMC Sierra models with a 5-foot-10-inch bed measuring 69.9 inches. The listing specifies MultiPro/Flex tailgate fitment and describes an upgraded auto-latch locking system.
Best for: Silverado or Sierra 1500 owners seeking a hard-folding cover for the stated bed length. Choose it if your model year and tailgate configuration match the listing.
Check before buying: This cover will not fit a Carbon Pro bed. Verify the bed material, tailgate, model year, and dimensions before ordering.
BAKFlip MX4 for GM 2500 and 3500
This hard-folding MX4 fits listed 2020–2026 Chevy Silverado and GMC Sierra 2500/3500 trucks with a 6-foot-10-inch bed measuring 82.2 inches. Its listed security feature is the updated patented auto-latch locking system.
Best for: Owners of the specified GM heavy-duty trucks who want a folding hard cover. It is a separate fitment from the GM 1500 version, despite sharing the MX4 name.
Check before buying: The listed fitment is for an 82.2-inch bed. Confirm both the truck’s series and bed measurement; this is not identified as a universal GM cover.
Retractable Hard Cover for GM 1500
This retractable cover is listed for 2014–2026 Chevy Silverado and GMC Sierra 1500 trucks with a 5-foot-8-inch, 69-inch bed. It uses aluminum slats with a matte black powder-coated finish, a key lock with two keys, rubber seals, foam padding, and an integrated water-management system. The listing describes the cover as nearly leak-proof when correctly installed.
Best for: GM 1500 owners who prefer a retractable design and want a traditional key lock. It offers a different opening style from the folding MX4 covers.
Check before buying: The product description says the locking behavior depends on cover position and manual strap movement when partly open. Confirm the bed dimensions and follow the installation and operation instructions.
BAKFlip MX4 for Ford Super Duty
This MX4 is listed for 2017–2026 Ford F-250 and F-350 Super Duty trucks with a 6-foot-10-inch bed measuring 81.9 inches. Like the other MX4 options here, it features the described upgraded auto-latch locking system.
Best for: Super Duty owners who want a hard-folding cover matched to the listed long bed. It was selected as the Ford heavy-duty alternative to the GM 2500/3500 MX4.
Check before buying: The listed bed length is specific. Check the truck year and bed measurement carefully, because the F-250/F-350 name alone does not establish fit.
Buying Guide: How to Choose a Truck Bed Cover
Which bed length should you measure?
Start with the truck’s exact year, model, bed length, and bed configuration. Compare those details with the product’s listed measurements, not just a rounded description such as “short bed.” The products above range from 67.1 inches to 82.2 inches and are not interchangeable.
Should you choose a folding or retractable cover?
A folding cover opens in hinged sections, while the listed GM retractable cover rolls or slides back into its storage area. Choose based on the access style you prefer and the cover’s fitment. The MX4 listings emphasize an auto-latch system; the retractable option specifies a key lock and aluminum slats.
What fitment details matter beyond the truck name?
Check the model year, series, bed size, tailgate, and any special bed construction. For example, the GM 1500 MX4 listing specifies MultiPro/Flex tailgates and excludes Carbon Pro beds. When the listing does not provide a detail you need, verify it with the seller before purchasing.
How should you compare weather protection?
The retractable cover listing describes rubber seals, foam padding, and water management, while the MX4 details provided emphasize fitment and the locking system. Do not assume any cover is completely waterproof based on a general description. Correct installation and truck-bed conditions can affect water management.
