The BAKFlip MX4 is a premium tonneau cover designed for pickup trucks, offering a balance of durability, functionality, and ease of installation. While installation procedures can vary slightly depending on the truck model—such as Ram 1500 or Ford F-150—core principles generally remain consistent across applications. This article provides a detailed, accurate, and methodical overview of the BAKFlip MX4 installation process, based on information from verified installation instructions, user-reports, and official documentation. It also addresses compatibility considerations, common challenges, and time expectations for users planning the installation themselves or seeking to understand what to expect when selecting this cover.
Pre-installation Considerations
Prior to installing a BAKFlip MX4, it is essential to assess compatibility, select the correct model for the truck bed dimensions, and obtain the appropriate installation instructions. The manufacturer has made it clear that the MX4 is engineered to integrate with the truck bed’s existing structure—avoiding unnecessary drilling or permanent modifications in most cases.
BAKFlip recommends consulting the documentation that accompanies the MX4 or accessing supplemental installation sheets tailored to specific models, such as Toyota, Nissan, Ford, and Ram. These sheets are often necessary to ensure the alignment of hardware with factory rails or built-in tie-down systems. For example, Ram models with RamBox—the integrated under-bed storage compartments—require a version of the MX4 designed with specialized mounting brackets to preserve both tonneau functionality and storage access.
Additionally, installing the MX4 over a spray-in bed liner is generally preferable, as drop-in liners may require trimming or hardware repositioning to accommodate the mounting system. Since the MX4 is engineered with factory-grade fasteners and materials, correct alignment and fitment are crucial to both performance and aesthetics. Users are encouraged to measure the truck bed carefully and cross-reference these dimensions with the tonneau cover specifications provided by the manufacturer.
Installation Steps and Tools Required
The BAKFlip MX4 is designed for do-it-yourself installation, although it is not considered a beginner-level task. Installers should expect to spend approximately two to three hours with standard tools and some mechanical familiarity. The process generally follows a logical sequence:
Prepare the Workspace: Clear the truck bed of any debris or loose items that might interfere with hardware placement. If using a spray-in bed liner, ensure it is fully cured.
Position the Rails: Lined up with the factory bed rails or with a modified set for RamBox systems, the BAKFlip M4’s mounting rails are installed as the backbone of the system. Proper rail alignment avoids binding and ensures smooth cover operation.
Secure the Rails to the Truck Bed: Using supplied bolts and wrenches, fasten the rails to the bed rails or tie-down points. Tighten all hardware to the manufacturer’s torque specifications, referencing the installation manual for precise guidance.
Attach the Cover Panels: The MX4 comprises multiple hinge assemblies secured to the rails. These panels are then linked together in a hinged fashion to create the full-length cover system. Careful attention is required during this phase to avoid misalignment.
Sealing and Adjusting the Front Edge: A critical part of installation involves sealing the front edge of the cover. The MX4 features a proprietary system that adheres to the bed and can be adjusted for proper tension to ensure a snug and weather-resistant fit.
Testing and Adjustment: Once the cover is assembled, the installer should manually operate the MX4 to verify that all panels open and close smoothly, that there is no resistance at the hinges or locking points, and that the cover lies evenly against the truck bed when closed.
Installation tools typically include a standard set of hand tools such as screwdrivers, wrenches, and pliers. A marker or measuring tape may also be necessary for marking hardware locations, especially when fine-tuning the position of the rails or making minor adjustments during the process.
Handling Specific Installation Challenges
BAKFlip MX4 installation can present a few common challenges, even among experienced DIYers. Here is a breakdown of typical issues and how to address them based on available information:
Bed Liner Compatibility: If your truck bed features a drop-in bed liner, it may need slight trimming to allow the mounting brackets to sit properly. Use a utility knife carefully, and always test fit the hardware before making permanent cuts. For spray-in liners, minor pressure adjustments from the MX4 mounting system typically do not cause damage, but monitoring the integrity of the liner after installation is advisable.
Tailgate Clearance: In models with aftermarket tailgates or modified tailgate setups, the MX4 panels must be adjusted to ensure they do not interfere with tailgate operation. Users are advised to measure clearance between the open panel and the tailgate when the truck bed is fully loaded. Minor adjustments to the hinge angle or cover height, as provided in the installation documentation, should suffice in most cases.
Rail Positioning and Alignment Issues: For trucks with irregular bed rails or custom setups, rail misalignment can occur. If this happens, the solution generally involves minor repositioning of the MX4’s rails relative to the truck’s factory structure. Some users with Ram models noted the need to test different rail positions for optimal balance and sealing. It is important to follow the MX4’s rail templates closely to avoid installation errors.
Drainage Installation: The MX4 includes a built-in drainage system to prevent water retention behind the cover. Proper installation of this system involves routing the drainage tubes correctly and securing their outlets. Neglecting this step can lead to water damage over time, especially in areas prone to rain and moisture. Users should carefully follow the drainage tubing instructions, ensuring the final location of the drain is accessible and protected from blockages.
Mounting Hardware Fitment: Due to variations in factory bed rail widths or thicknesses, some MX4 installations may require minor adjustments to the mounting brackets. The manufacturer often supplies extra washers or spacers under such circumstances, but if these are not available for a specific model, users may need to source hardware compatible with their truck’s dimensions.
Professional vs. DIY Installation Options
While the BAKFlip MX4 is marketed as a DIY-friendly installation, there are also professional installation options available for those who prefer expert assistance or need help addressing unique truck configurations. Many truck accessory shops and car dealerships in the U.S. offer installation services for MX4 systems, especially Ram 1500 models, where RamBox compatibility is a known complexity.
Professional installers typically have the tools and experience required to handle these setups quickly and accurately. They are also often familiar with bed liners, aftermarket parts, and vehicle-specific details that may affect the MX4’s performance and aesthetics. Some users may opt for professional installation if they are pressed for time, if the installation requires significant tool usage or if their truck model presents unusual variations that might require custom adjustments.
That said, the documentation from BAKFlip indicates that the majority of MX4 owners successfully install the cover themselves. With patience and attention to detail, even first-time installers can achieve a well-finished result that meets all manufacturer specifications.
Time and Labor Expectations
According to user reports and official guidance, installing the BAKFlip MX4 generally takes between 2 to 3 hours for first-time users and can be completed in less than two hours for those with prior experience. The majority of the time is typically spent in the initial setup of the rails and panels and finalizing the sealing of the front edge.
Here is an expected breakdown of time allocation for a standard Ram 1500 installation:
- Setup and Preparation (30 minutes): Clearing the truck bed, gathering tools, and reviewing the manual.
- Rail Installation (60 minutes): Positioning and mounting the rails.
- Panel Attachment (45 minutes): Securely mounting each panel and adjusting connections.
- Front Seal and Adjustments (30 minutes): Final testing and seal adjustments.
- Final Fit and Testing (15 minutes): Ensuring smooth and fully sealed operation.
For Ford F-150 models (similar to Ram), the user-reported experience is comparable—with an hour being the total time for someone who has already done an MX4 installation. The ease of installation on F-150 is often attributed to the squared design of the rails, which allows for straightforward alignment without extensive shimming.
BAKFlip MX4 Pricing and Value Considerations
The BAKFlip MX4 typically falls within the $1,200 to $1,500 range, depending on the specific model and bed size. This price reflects the advanced materials, such as aluminum construction, weatherstripping technology, and adjustable panels, which contribute to the cover’s durability and performance.
