Featuring a patented auto-latch locking system, reinforced aluminum and polymer construction with 22% increased strength, and advanced weatherproof seals, it offers superior security and protection in extreme climates. Its sleek, flush-mount design provides full bed access while maintaining a low profile, backed by a 5-year warranty and easy installation. ## Description The best-selling truck bed cover in the world just got better. Introducing the new and improved RealTruck BAKFlip® MX4 (GEN3 Model Year 2025)—an evolution of RealTruck’s most popular tonneau cover. This next-generation upgrade builds on everything truck owners already love about MX4, now enhanced with improved functionality, greater durability, and elevated security. The new and improved BAKFlip MX4 is constructed primarily from alloy materials, including heavy-duty aluminum top panels and side rails. Reinforced with high-density polymer cores, each panel delivers a 22 percent increase in overall strength compared to the original model. Security is also enhanced. In addition to BAK’s patented auto-latching system, which automatically secures the cover when closed, the BAKFlip MX4 (GEN3) features re-engineered lock components for improved resistance to forced entry compared to the GEN2. No matter the cargo you’re transporting, you can rest assured knowing your gear’s protected. When the weather turns, the BAKFlip MX4 (GEN3) holds strong. Revised EPDM rubber perimeter seals and tight-fit clamps provide our best seal yet, preventing seepage between the bed cover and bed rails. At the rear of the cover, a 13 percent longer dual-action tailgate seal provides weather protection for the tailgate. The BAKFlip MX4 isn’t only durable, it’s also sleek and stylish. Unlike competitors, the BAKFlip MX4 sits flush with your pickup’s bed rails, practically disappearing into your truck’s profile. And with a sleek, textured matte black finish across all surfaces, the MX4 looks great whether open or closed. Installation is streamlined thanks to an improved click-in mounting system, reducing setup time by 12 percent. Operating the cover is just as simple—drop the tailgate, release the rear latch mechanism, and fold the cover toward the bulkhead. If full bed access is required, fold the cover flush against the rear window—third brake light visibility remains unobstructed in any position. ## Features - Fits 2021 - 2027 Ford F-150 6' 7" Bed (78.9") - THE ORIGINAL.

All I see is ford** A: The BAK BAKFlip MX4 Hard Folding Truck Bed Tonneau Cover you mentioned, with part number 448339, is specifically listed as fitting the 2021 - 2023 Ford F-150 models with a 5' 7" bed. Based on the information provided, it appears that this particular tonneau cover is designed and intended for Ford F-150 trucks, and there is no indication of it being compatible with Chevy trucks. If you are looking for a tonneau cover for your Chevy truck, I would recommend looking for options specifically designed to fit your Chevy model and bed size. It's important to ensure that the tonneau cover you choose is compatible with the specific make, model, and bed size of your truck to ensure proper fitment and functionality. **Q: where is the part number located.? I don’t see no white sticker on bottom and no box** A: I can't help you. I got a Bak Flip G2. **Q: How durable is the MX4? Read many reviews of this tonneau cover denting easily.** A: Its as tough as they come. I've had my 4 year old nephew standing on it and no flex at all. Plus its so easy to install and operate, hell my wife finds it easy to use. Its made with top notch materials and looks great on the truck. I had friends see mine and bought one just from sight. we love ours and have no issues with it at all. Its a solid buy!! **Q: Will this fit a 2023 f150** A: With a New Model Year F-150 it would be best to contact the manufacturer directly. Although they do reference it fitting 2021-2023. Mine is an Older Model and it fit correctly. ## Frequently Bought Together - RealTruck BAK BAKFlip MX4 Hard Folding Truck Bed Tonneau Cover | 448337 | Fits 2021-2025 Ford F-150 6' 7" Bed (78.9") - Husky Liners Custom Bed Liner | Fits 2015-2024 Ford F-150 (78.9 Bed) | 1-pc.
