If you drive a 2005-2021 Nissan Frontier and 2009-2012 Suzuki Equator with a 5' bed, the BAKFlip MX4 (Gen 3) Hard Folding Tonneau Cover 448506 is a cover to look at. The hard panels protect your cargo from weather and prying eyes, and the folding design opens the bed in one move.
The BAKFlip MX4 is BAK's step-up folding cover. This Gen 3 version adds stronger panels, a tighter seal and a re-engineered auto-latch.
A cover on the Frontier locks the bed's contents out of sight and keeps weather off them while still opening up for bigger loads.
Tougher than the original. BAK rebuilt the MX4 panels in layered aluminum with a high-density polymer core, a 22% strength increase over the first-generation cover. Aluminum rails and a stiff frame support up to 400 lb of evenly distributed cargo on top.
Full bed access without taking the cover off the truck. Fold it toward the bulkhead, let the prop rod clips hold it open, and load tall or bulky cargo. The bumpers keep the cab protected, and the third brake light stays visible whether the cover is open or closed.
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.
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.
A low, tidy profile. Textured matte black on every component and a flush fit with the rails make the cover look like it belongs on the truck.
Assembled in the USA and covered by a five-year limited warranty, the BAK 448506 is the Gen 3 upgrade for owners who want a stronger, tighter-sealing folding cover. Order it from Track Ready Products and check the bed length above.
Installation is a one-person, bolt-on job with a click-in design that is 12% quicker than the previous generation. Most trucks need no drilling or trimming.
Start with a clean set of rails. Position the cover, tighten the clamps evenly, and run it through a full open and close cycle to check that it moves freely and latches.
Recheck the clamps after about a week, wash with mild automotive soap and water, and clear off snow and ice before opening. Keep the cover secured at all points whenever you drive.
