BAKFlip is BAK’s family of hard folding tonneau covers (now sold under the RealTruck name), and it’s one of the best-known names in truck bed covers. The lineup includes the BAKFlip G2, MX4, F1 and FiberMax, and BAK also makes the Revolver X4s hard rolling cover. Every BAKFlip is made for a specific truck, year range and bed length, and some depend on your tailgate or bed type. This guide explains the BAKFlip lines and shows listings for popular trucks, with the exact fitment each one states.
How we chose: this guide is based on BAK’s product lines and the fitment, part numbers and bed lengths in each Amazon listing title. We haven’t hands-on tested these covers. Measure your bed and check the listing’s fit notes, especially tailgate and bed-option exclusions, before ordering.

How BAKFlip Covers Work
A BAKFlip is a hard folding cover. Its rigid panels fold forward toward the cab, so you can open just the back of the bed for quick access, or fold it up to open most of the bed for tall loads. When it’s closed and the tailgate is locked, the bed is covered and secured.
The Revolver X4s is different: it’s a hard rolling cover that rolls up toward the cab. Folding covers usually leave a stack of panels at the front of the bed when open. Compare both styles in our best hard folding tonneau cover and pros and cons of truck bed covers guides.

Who a hard cover is NOT for: owners who often haul tall loads like furniture or dirt bikes and need the whole bed open fast. A soft roll-up or a retractable cover may suit better. See our Retrax guide.
How to Order the Right BAKFlip
- Measure your bed length at the rails, and compare it with the inches in the listing title.
- Check tailgate and bed options: MultiPro/Flex, Carbon Pro, RamBox and factory track systems all change the part number.
- Match the model years: body changes (for example F-150 2015-2020 vs 2021+) mean different covers.
- Consider racks and toolboxes: if you run a bed rack or crossover toolbox, check that the cover works with it.
