BAK Industries 448122 BAKFlip MX4 Hard Folding Tonneau Cover Matte Aluminum

The BAK Industries BAKFlip MX4 (448122) is a hard folding truck bed tonneau cover engineered for maximum security, all-weather protection, and a clean, low-profile appearance. Constructed with heavy-duty aluminum matte finish panels reinforced with a premium density foam core, the MX4 delivers outstanding scratch, scuff, and UV resistance while keeping your truck looking sharp.

Key Features:

• Heavy-duty aluminum construction — Matte-finished alloy top panels and side rails reinforced with high-density polymer cores for a 22% increase in overall strength
• Patented auto-latching system — Panels automatically secure when the cover is partially or fully closed; fully locked when the tailgate is closed
• Injection-molded latch housing — Engineered for long-term durability and improved resistance to forced entry
• EPDM rubber perimeter seals — Revised seals and tight-fit clamps prevent water seepage between the bed cover and bed rails
• Dual-action tailgate seal — Maintains factory tailgate functionality whether the cover is open, folded, or flipped; seal is 13% longer for enhanced rear weather protection
• 100% truck bed access — Folds up neatly behind the cab; can be driven with cover in closed, folded, or fully flipped-up position without obstructing the 3rd brake light
• Rated up to 400 lbs. of evenly distributed weight on top of the panels
• Flush-mount, low-profile design — Sits flush with the bed rails for a sleek, integrated look
• Matte-finished cab corner caps, clamps, and elevator bolts for a streamlined, cohesive appearance
• Pre-molded, die-cut shock-absorbent bumpers and secure prop rod clips for enhanced functionality
• Assembled in Missouri, USA — Backed by a 5-year warranty against manufacturing and material defects

The BAKFlip MX4 hard folding tonneau cover is the ideal upgrade for truck owners who demand a rugged, all-season bed cover that combines security, weather protection, and everyday practicality without sacrificing style.
