Description

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.

    Had the cover installed a week ago. Nice folks and looks clean. It has not rained yet so, waterproofing not confirmed. The cover is heavier than I expected.

Fast, friendly service! Eric was a pleasure to work with in taking care of an insurance claim for my damaged truck bed topper for my 2007 Ford F150. The new topper was delivered and installed the very next day! It looks great...a lot better than the one I had on there!!! I highly recommend Leer Truck Accessories of Conyers for all your truck accessory needs!

I understand now why LEER has such high reviews. Blake and Justin create an environment that is completely stress free. Their knowledge and communication skills are top notch. My trailer hitch install was complete in less than an hour. Make the call, you won't be disappointed!!

Wonderful people to work with. I have had both a Tono cover and mudflaps installed. They even helped finish up a taillight installation that I almost completed. These are the best people that I know to go get anything for your truck. I would recommend them highly!

Called the night before for a repair on the trailer. They were there at the exact time they said they would be and was very quick with the service. The technicians were very kind and polite, they even explained some parts and how they worked. Will definitely be back if i have any issues in the future when in the area.

I recommend for anyone needing upgrades to their vehicle. I was in and out in an hour for my lightning installation. I'll be back.
