BAK Industries BAK-448309 BAKFlip MX4 Hard Folding Tonneau Cover Matte Black Aluminum

The BAK Industries BAKFlip MX4 (448309) is a premium hard folding truck bed tonneau cover engineered for maximum protection, security, and all-weather performance. Constructed from heavy-duty aluminum top panels and side rails with a high-density polymer core, this cover delivers a sleek, low-profile flush-mount look while supporting over 400 lbs of evenly distributed load.

Key Features:

• Heavy-duty aluminum construction — alloy top panels and side rails with high-density polymer core provide a 22% increase in overall strength over the original model
• Matte black finish — UV-resistant and scratch-resistant matte coating maintains a clean, factory-style appearance
• Patented auto-latch locking system — automatically secures the cover when closed; re-engineered lock components offer improved resistance to forced entry
• Integrated tailgate seal — allows the cover to be opened or closed with the tailgate in any position
• EPDM rubber perimeter seals — blocks moisture seepage between the cover and bed rails for superior weatherproofing
• Full truck bed access — panels fold forward to the cab, securing in the open position for complete bed access
• No-drill installation — all-new click-in design with tight-fit clamps installs in under 30 minutes for most applications; all hardware included
• All-season durability — tested from -40°F to 180°F and zero to 95% humidity
• Flush-mount, low-profile design — sits inside the bed rails for a clean, streamlined look
• 5-year warranty — backed by a 5-year limited warranty against manufacturing and material defects

The BAKFlip MX4 features matte-finished cab corner caps, clamps, and elevator bolts for a cohesive, streamlined aesthetic. Pre-molded, die-cut, shock-absorbent bumpers and secure prop rod clips add to the cover's premium build quality. Note: Not compatible with models equipped with a factory cargo channel system.
