Featuring durable aluminum panels with automatic latching and tailgate locking, a scratch- and UV-resistant matte finish, and full bed access without obstructing the 3rd brake light, this cover combines security, style, and convenience in a precision-fit, American-made package. ## Description America’s best-selling truck bed cover just got even better.Introducing the BAKFlip MX4 Gen 3—the latest evolution of RealTruck’s most popular tonneau cover. Now better than ever, the BAK has redesigned the for improved strength, security, and all-weather performance. The Gen 3 MX4 features alloy-based construction, including heavy-duty aluminum side rails and top panels, reinforced with high-density polymer cores. This updated design delivers a 22 percent increase in strength over the previous generation, making it even more capable of handling daily use, heavy loads, and harsh environments. Security has also been upgraded. BAK’s patented auto-latching system secures the cover automatically when closed. Newly engineered lock components provide added resistance to tampering and forced entry, allowing you to transport your gear with confidence. In rough weather, the Gen 3 MX4 holds strong. Revised EPDM perimeter seals and tight-fit clamps offer the best seal yet, helping prevent water intrusion along the bed rails. A longer dual-action tailgate seal weatherproofs the tailgate while preserving full functionality, whether the cover is open or closed. While the MX4 is built tough, it doesn’t compromise on looks. The flush-mount design gives it a sleek, low-profile appearance, while a textured matte-black finish across all surfaces delivers a clean, subtle aesthetic. Installation is easier than ever with a new click-in rail system that cuts install time by up to 12 percent. Day-to-day use is just as simple—drop the tailgate, unlatch, and fold the cover forward. For complete bed access, fold the cover against the cab without blocking your third brake light. The BAKFlip MX4 Gen 3 is proudly assembled in Missouri using globally sourced materials and backed by a 5-year warranty. Review: Installation manual is worthless - Great product! The only problem is they need to update their installation manual. The included manual is a general one and not vehicle specific. I also visited their website and downloaded the manual based off my vehicle year, model and product model and it was the same general installation manual. I looked it up on you tube and found a great installation video by a car shop. Otherwise a great product.

When purchasing from a retailer we would follow that retailers guidelines. For warranty on any new purchased covered you would reach out to us direct (the manufacturer at www.bakindustries.com) for warranty assistance. Depending on the cover and when it was purchased the warranty coverage period could range from 1-5 years for manufacturer defect in workmanship and material. you can see the full warranty policy on our website. **Q: I have a 2018 dodge ram 2500 with a 6’4” bed and rambox. Is there a Tonneau cover that will fit this truck and still be able to open up the ramboxes?** A: Check BakFlip because they fold up all the way where most others have a flap that remains in place, unless the whole assembly is removed. **Q: Does this fit the 2016 ram 1500 6’4 bed with ram boxes?** A: Yes. Got it for my 2013 Ram 1500 with Ram Boxes. It says it in the description, and clearly shows a black truck with Ram Boxes utilize this product. **Q: Will this fit 2020 2500 ram 6.4 bed with ram box ?? thank you** A: No, the BAK BAKFlip MX4 Hard Folding Truck Bed Tonneau Cover you mentioned is designed to fit 2012-2021 Classic Dodge Ram 1500 models and 2012-2021 Ram 2500/3500 models with a RamBox and a 6' 4" bed (76.3"). It does not specifically mention compatibility with the 2020 Ram 2500 model. Therefore, I would recommend checking with the manufacturer or a trusted retailer to confirm whether it will fit your specific 2020 Ram 2500 with a 6.4' bed and RamBox. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Installation manual is worthless *by H***Z on December 16, 2019* Great product! The only problem is they need to update their installation manual. The included manual is a general one and not vehicle specific. I also visited their website and downloaded the manual based off my vehicle year, model and product model and it was the same general installation manual. I looked it up on you tube and found a great installation video by a car shop. Otherwise a great product. ### ⭐ Great product if you can get the hardware *by J***G on April 30, 2019* The product didn't come with the rails or hardware to install waiting on parts ### ⭐⭐⭐⭐⭐ Looks good Ram 1500 *by G***O on January 22, 2022* The BAKFlip looks good and was relatively easy to install for an octogenarian. After washing the truck I saw no water in the bed. I did not spray directly on the BAKFlip but a lot of water splashed on it and the bed remained dry. I will see what happens in the rain. ## Frequently Bought Together - RealTruck BAK BAKFlip MX4 Hard Folding Truck Bed Tonneau Cover | 448203RB | Fits 2012 - 2023 Dodge Ram 1500, 2012-21 2500/3500 w/RamBox 6' 4" Bed (76.3") - Rear Bed Step Compatible with Dodge Ram 2500 3500# 2019 2020 2021 2022 2023 2024 Retractable Bumper Tailgate Step 82215842AH 82215842AD 82215842AE 82215842AC - PIMCAR Center Console Organizer Upgrade Flocked Liner Interior Compatible with Dodge RAM 1500 2500 3500 2019-2024 2025 ABS Plastic Material Shell Armrest Box Insert Tray Accessories --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/56909299-bak-bakflip-mx4-hard-folding-truck-bed-tonneau-cover-448203rb](https://www.desertcart.vn/products/56909299-bak-bakflip-mx4-hard-folding-truck-bed-tonneau-cover-448203rb) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-06-09*
