BAKFlip MX4 448130 | Hard Folding Tonneau Cover for Ford F-150
Our BAKFlip MX4 448130 is engineered specifically for Ford F-150 pickups with a 70-inch bed, delivering the perfect balance of security and convenience. This hard folding tonneau cover features powder-coated aluminum panels that protect your cargo from weather and theft while maintaining a sleek, low-profile appearance.
The MX4 folds completely open for full bed access or stops at multiple positions along the way, giving you the flexibility to haul taller items without removing the cover. We built the 448130 with our signature FRP (Fiber Reinforced Polymer) panels that are lightweight yet incredibly durable, and the cover installs in minutes using integrated clamps—no drilling required.
MX4 448130 specifications & design highlights
Materials & Construction Details
We manufacture the 448130 using our proven aluminum panel construction reinforced with a Fiber Reinforced Polymer core. This combination delivers exceptional strength-to-weight ratio—strong enough to support 300 pounds yet light enough for one person to operate.
The powder-coated matte finish resists scratches from sliding cargo and withstands years of UV exposure without fading. Each panel connects with heavy-duty aluminum hinges that we’ve tested through hundreds of thousands of fold cycles. The integrated drain channels route water away from your bed, and the dense EPDM rubber seals keep dust and moisture out even during highway driving.
Installation & Bed Compatibility
Quick Clamp Installation
The 448130 installs on your Ford F-150 without drilling holes or using adhesives. We include integrated clamps that attach directly to your truck’s bed rails—simply position the cover, tighten the clamps with the included hex key, and you’re ready to drive.
Most customers complete installation in 15-20 minutes. The cover fits 2015-newer Ford F-150 models with the 70-inch bed configuration, also known as the 5’9″ bed or short bed. We designed the 448130 to work with factory bed rails and most aftermarket bed liners, including spray-in liners like LINE-X and drop-in liners.
Operating the Folding Panel System
The MX4 448130 operates on our signature four-panel folding system. Each panel folds independently, and the integrated hinges hold panels at 90-degree intervals without props or supports.
To access your cargo, release the automatic latch by opening your tailgate. Lift any panel from the rear, and it will stay in position. Fold all four panels forward against the cab for complete bed access—the entire operation takes seconds. When you’re ready to close, simply unfold the panels from front to back, and the spring-loaded latch automatically secures when the tailgate closes.

Common Questions About the BAKFlip MX4 448130
The 448130 is specifically designed for Ford F-150 trucks with a 70-inch bed (5’9″ short bed) from 2015 to current model years. It works with both gas and diesel engines and fits trucks with or without the Ford tailgate step.
Before ordering, verify your bed length by measuring from the inside of the bulkhead to the inside of the tailgate. If you have a different bed length, we offer other BAKFlip models for 65-inch and 80-inch F-150 configurations.
Yes, the MX4 448130 is fully compatible with spray-in bed liners including LINE-X, Rhino Lining, and Herculiner. Our rail clamps are designed to accommodate the additional thickness that spray-in liners add to your bed rails.
The cover also works with most drop-in bed liners. If you have an over-rail bed liner that sits on top of your bed rails rather than under them, you may need to remove it for proper 448130 installation.
The BAKFlip MX4 448130 supports up to 300 pounds when the weight is evenly distributed across the panels. This means you can safely kneel or stand on the cover when accessing cargo, and you can place items on top when the cover is closed.
We don’t recommend using the 448130 as a permanent roof rack or placing concentrated weight on a single panel. For heavy cargo rack applications, consider our BAKFlip CS model that includes an integrated rack system designed for higher loads.
Clean your MX4 448130 with mild soap and water using a soft cloth or sponge. Avoid abrasive cleaners, pressure washers aimed directly at seals, or harsh chemicals that can damage the powder coat finish.
We recommend applying a quality automotive wax to the aluminum panels every few months to protect the finish. Periodically check that the drain channels are clear of debris, and you can treat the rubber seals with a silicone-based protectant to maintain flexibility. The hinges are sealed and don’t require lubrication.
Yes, the BAKFlip MX4 448130 doesn’t interfere with factory Ford F-150 bed lighting. The cover’s low-profile design sits below most bed-mounted lights, and you’ll still have full illumination when the panels are closed.
If you have aftermarket LED bed lights mounted on the bed rails, you may need to relocate them depending on their position. The 448130 rail clamps require approximately 1.5 inches of clear rail space for installation along the length of your 70-inch bed.
The MX4 448130 folds completely forward against your cab, but if you have a front-of-bed toolbox, the cover will stop when it contacts the toolbox. Most low-profile toolboxes (under 12 inches tall) allow the panels to fold at least partially open.
For customers who want both a tonneau cover and secure in-bed storage, we recommend our BAKBox 2 folding toolbox that’s specifically designed to work under BAKFlip covers. It folds with your panels and doesn’t interfere with the 448130’s full range of motion on your 70-inch bed.
The BAKFlip MX4 448130 is highly water-resistant but not 100% waterproof. Our EPDM rubber seal system and integrated drain channels keep out the vast majority of water during normal driving and rain conditions.
In extreme conditions like pressure washing, driving through deep water, or stationary flooding, some moisture may enter. We always recommend using additional protection like plastic bins or tarps for items that must stay completely dry. The 448130 provides far superior weather protection compared to soft tonneau covers or no cover at all.
