The best-selling truck bed cover in the world just got better.
Introducing the new and improved RealTruck BAKFlip® MX4 (GEN 3)—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 (GEN 3) features re-engineered lock components for improved resistance to forced entry compared to the GEN 2. No matter the cargo you're transporting, you can rest assured knowing your gear's protected.
When the weather turns, the BAKFlip MX4 (GEN 3) 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. This innovative design also improves operation, maintaining factory tailgate functionality regardless of the cover's position.
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.

Every review below is a verified Google review of an H&H store — written by real customers about the people who sold, fitted and stood behind their gear.
H&H has now come to my family's rescue twice. Each time, due to unexpected circumstances, we needed a trailer hitch attached to our vehicle virtually immediately. Sean, the manager, went over and above to get the parts delivered overnight and get the hitch, including all wiring needed for the lights, installed the next morning after his first scheduled job. These are your guys if you need work done right and done quickly!!!
Excellent work,, outstanding staff, 5 STARS customer service ON ALL LEVELS!
Lucas the sales guy did a nice job walking me and my wife thru the process he kept his word by keeping us up to date on the building process….Justin and the crew did a great job installing our building on 9-17-2026 building looks even better then in the 3d image website they where professional and respectful the only thing I hated for them was they played music while they were assembling my garage and my neighbors called corporate on them and corporate instructed them to turn it down we how ever didn’t mind the music at all so if your reading this Justin we appreciate your help we love the garage thanks -the McIntyres

Trevor and his team did an outstanding job delivering my new 10' by 16' aluminum shed to a very tight delivery location. The shed is outstanding and I was glad I went with Thrifty Portable Building. I highly recommend them if you are looking for a portable building.
Fast! My order was ready, and installed in less than 24hrs! (Would have been sooner but I had to wait till next day) Staff was very friendly, will definitely be back!
Luke went out his way to make sure we had enough space for the delivery for our new shed!! Thanks Luke! You're awesome!!!!!!!
I had a problem with a tonneau cover almost blowing off. I patched it as best I could and visited H & H in Muscle Shoals to see if they could fix it even though it had been installed at a different H & H store. Rusty was kind enough to fix it easily. Highly recommend this individual.
Had the pool parts we needed and a lot of other things!
Great sales and installation teams. Fast , efficient, and professional.
