BAK Industries BAKFlip MX4 Hard Folding Tonneau Cover for 2015-2020 Ford F-150 & Raptor (5.5ft Short Bed)

The BAKFlip MX4 448329 Hard Folding Tonneau Cover offers high-grade bed protection, sleek utility, and long-term weatherproofing for 2015–2020 Ford F-150 and 2017–2020 Ford F-150 Raptor pickup trucks with a 5.5-foot short bed (5' 7" bed box). Engineered with heavy-duty aluminum top panels surrounding a high-density solid foam core, this cover supports up to 400 lbs. of evenly distributed load capacity.

Finished in a premium matte black powder coat, the MX4 resists UV degradation, scratches, and harsh environmental exposure across demanding Canadian winter conditions. Automotive cargo protection specialists note that the MX4’s dual-action tailgate seal allows the tailgate to close smoothly whether the cover is down or folded up, granting truck owners 100% full bed access without removing the cover assembly.
