- Compatible with all BAKFlip MX4 models 2015-present
Premium Materials & Construction
We manufacture every panel in the BAKFlip MX4 upgrade kit from the same aircraft-grade aluminum alloy used in our complete tonneau systems. The matte black powder coat finish provides superior UV resistance and prevents fading even after years of direct sunlight exposure.
Our weather seals use automotive-grade EPDM foam that remains flexible in temperatures from -40°F to 140°F. This material resists compression set, maintaining its sealing properties through thousands of open-close cycles. The stainless steel hardware throughout the kit includes Grade 8 bolts and marine-grade fasteners that won’t corrode in coastal environments or winter salt exposure.
Installation Process & Timeline
Installing your bakflip mx4 upgrade kit typically takes 45-60 minutes with basic hand tools. We include a complete hardware set with the exact torque specifications needed for secure mounting without over-tightening.
The process begins with removing your existing panels by loosening the hinge clamps and sliding each section free. Our pre-drilled panels align directly with your current mounting points, eliminating any guesswork during installation. You’ll apply the new weather seals along the designated channels, then secure each panel starting from the cab-side forward.
Compatibility & Fit Specifications
This upgrade kit fits all BAKFlip MX4 tonneau cover systems manufactured from 2015 to present across full-size truck platforms. We’ve engineered the components to work with bed lengths from 5.5 feet to 8 feet without any adapter plates.
The kit is compatible with trucks equipped with bed liners, spray-in coatings, and most aftermarket bed accessories. Our panels maintain the low-profile design that preserves your truck’s aerodynamics while allowing full tailgate operation. You can verify compatibility by checking your existing cover’s serial number stamped on the cab-side rail.

Questions About the MX4 Upgrade Kit
Yes, our upgrade kit is fully compatible with spray-in bedliners and drop-in liners. The mounting clamp assemblies include adjustable blocks that accommodate up to 0.5 inches of additional thickness from liner coatings.
You may need to slightly loosen the clamps during initial installation to account for the liner, then tighten to the specified 15 ft-lbs torque. The weather seals compress properly regardless of liner type to maintain a weathertight seal.
Our seven-stage powder coat process creates a finish rated for 10+ years of outdoor exposure without fading or peeling. The coating resists UV radiation, salt spray, and temperature extremes from -40°F to 140°F.
We've tested the finish through accelerated weathering equivalent to 15 years of daily sun exposure. Regular washing with automotive soap helps maintain the matte appearance, though the protective properties remain intact even if the surface dulls slightly over time.
Yes, we stock individual replacement panels if you only need to replace damaged sections rather than the entire set. Each panel is available separately through our parts department.
However, the complete bakflip mx4 upgrade kit offers better value when replacing multiple components since it includes all hardware and seals at a bundled price. Contact our support team to discuss which option makes sense for your specific situation.
This upgrade kit provides all the wear components—panels, seals, and hardware—while utilizing your existing rail system and hinge assemblies. You'll achieve like-new performance at roughly half the cost of a complete replacement cover.
The kit is ideal when your rail system and hinges are still in good condition but the panels show wear or the seals have compressed. If your rails are damaged or you're changing truck models, a complete new cover would be the better choice.
Common signs include water leaking into the bed during rain, visible gaps between panels when closed, difficulty latching the cover securely, or faded/scratched panel surfaces. If you notice the weather seals are compressed flat or cracking, the upgrade kit will restore proper sealing.
Most covers benefit from this upgrade after 5-7 years of regular use, though harsh climates or heavy-duty applications may require earlier replacement. Inspect your seals and panel condition annually to catch wear before it leads to cargo damage.
The installation process is designed for DIY completion with basic hand tools. Most truck owners complete the upgrade in 45-60 minutes following our detailed instructions with step-by-step photos.
No special tools beyond a socket wrench, screwdriver, and torque wrench are needed. We recommend having a second person available to help align the panels during initial positioning, though solo installation is possible. Our technical support team is available by phone if you have questions during the process.
Our 2-year warranty covers manufacturing defects in materials and workmanship but doesn't include damage from accidents, improper installation, or modifications. We recommend following the torque specifications and installation sequence exactly as outlined in the instructions.
If you're uncertain about any installation step, contact our support team before proceeding. We can troubleshoot issues to ensure proper fitment, which helps prevent problems that would fall outside warranty coverage. Impact damage from collisions or cargo isn't covered, though individual replacement components are available for purchase.
