## 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: Installs easy, looks great, seems to function well on initial review - Just installed it today and drove around for a few hours. Really good fit. Installation took me about 45 minutes. Very straight forward. Materials are all high quality. Finish is good. It either made it quieter or it quieted some of the frequencies that are most obnoxious. It rolls up tight and compact. It doesn't have a lock but when the tail gate is locked you can't open it. I think a real dedicated thief could get through, but it will stop those looking for just an easy target. Overall super happy.
Review: Fair price and quality product! - Far lighter in weight than the previous model I had installed on my f150. Same quality but much easier to fold back to utilize the entire space in the bed. Easy to self install and the quality of product make this a great option for covering the bed of your pickup.

## Questions & Answers

**Q: Does it fit a chevy truck? 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.
