If you drive a 2015-2020 Ford F-150 with an 8' bed, the BAKFlip MX4 (Gen 3) Hard Folding Tonneau Cover 448328 is a cover to look at. It is a hard folding tonneau cover, so you get lockable cargo protection and a bed that opens up when the job needs it.
As a Gen 3 BAKFlip MX4, this cover raises the load rating to 400 lb and improves the seals and latching.
The F-150 bed does a lot of different jobs. A hard cover protects the cargo on the way, and opens fully for the jobs that need the space.
Close it and walk away. The auto-latch does the locking, and the re-engineered lock components give this generation better resistance to forced entry than the last.
Fold it up and haul. The cover folds forward and upright against the cab, with prop rod clips holding it in place and rubber bumpers protecting the cab. You can drive with it folded open, and the third brake light is not blocked in any position.
Gen 3 strength. The top panels are multi-layer aluminum over a high-density polymer core and are 22% stronger than the original MX4, while precision-engineered aluminum side rails and frame keep the cover rigid. It is rated for 400 lb of evenly distributed weight.
Clean lines. Textured matte black covers the panels, rails and clamps, and the flush fit along the bed rails keeps the profile low.
Edge-to-edge sealing. New EPDM perimeter seals and tight-fitting clamps reduce seepage at the bed rails, the dual-action tailgate seal is 13% longer on most applications, and built-in water drainage moves moisture out of the way.
For a folding cover that locks itself, seals tight and fits flush, the BAK 448328 is a strong choice. It is assembled in the USA, backed by a five-year limited warranty, and available from Track Ready Products.
The Gen 3 click-in mounting makes this a one-person job, typically 30 minutes or less, with no cutting, trimming or drilling on most trucks. Clamps and hardware are included.
Clean the bed rail caps first so the seals sit on a clean surface, set the cover in place, and tighten the clamps evenly from side to side. Work the cover open and closed once before you load the bed.
Care is simple: mild automotive soap and water for cleaning, a clamp check after about a week and periodically afterward, the cover secured whenever the truck is moving, and snow and ice cleared before you open it.
