BAK Industries BAK-448701 BAKFlip MX4 Hard Folding Tonneau Cover Matte Black Aluminum

The BAK Industries BAKFlip MX4 (448701) is a premium hard folding truck bed tonneau cover engineered for durability, security, and all-season protection. Constructed from heavy-duty aluminum top panels and side rails reinforced with a high-density polymer core, each panel delivers a 22% increase in overall strength compared to the original model, while a UV-resistant matte black finish provides advanced scratch and scuff resistance.

Key Features:

• Hard folding aluminum panels with premium-density foam core and matte black powdercoat finish
• 400 lb. load rating for evenly distributed weight on top of the cover
• Dual-action integrated tailgate seal allows the tailgate to be opened or closed regardless of cover position
• Patented auto-latching system with re-engineered injection-molded latch housing for enhanced forced-entry resistance
• Integrated buckle system secures the cover in the folded position at highway speeds — no straps or bungee cords required
• EPDM outer rail seals for maximum water and weather resistance
• Pre-molded, die-cut, shock-absorbent bumpers and secure prop rod clips for 100% full bed access
• Matte-finished cab corner caps, rail-end caps, clamps, and elevator bolts for a streamlined, flush-mount appearance
• Toolbox compatible (compatible with BAKBox 2)
• No-drill, bolt-on installation using included tight-fit clamps — typically completed in 30–45 minutes
• Manufactured in the USA
• Backed by a 5-Year Limited Warranty against manufacturing and material defects

The BAKFlip MX4 is tested in extreme conditions ranging from -40°F to 180°F and zero to 95% humidity, making it a true all-season hard tonneau cover. Its low-profile flush-mount design keeps your cargo dry and secure while preserving a clean, factory-integrated look.
