BAK Industries BAK-448223 BAKFlip MX4 Hard Folding Tonneau Cover

The BAK Industries BAKFlip MX4 (448223) is a premium hard folding truck bed tonneau cover engineered for the Dodge Ram 1500 with a 6' 4" bed (76.3"). Constructed with heavy-duty aluminum top panels and side rails reinforced with a high-density polymer core, the MX4 delivers a 22% increase in overall strength over the previous generation — protecting your cargo in style without adding bulk.

Key Features:

• Aircraft-grade aluminum panels with a durable matte black powdercoat finish offering superior UV and scratch resistance
• Patented auto-latch locking system that automatically secures the cover upon closing — no separate action required
• Integrated tailgate seal allows the tailgate to open or close whether the cover is up or down
• Rated to support up to 400 lbs of evenly distributed static weight
• EPDM outer rail seals and precision-fit clamps create a tight edge-to-edge weather barrier to keep cargo dry
• Injection-molded latch housing components for long-term durability and enhanced resistance to forced entry
• Low-profile flush-mount design sits nearly flush with the bed rails for a clean, streamlined appearance
• Prop rods secure the cover in the fully folded position for 100% unobstructed bed access
• Toolbox compatible via under-cover mount; also compatible with bed rails
• Drain tubes require minimal drilling for installation; clamp-on mounting otherwise
• Tested from -40°F to 180°F and 0–95% humidity for year-round all-season performance
• Assembled in Missouri, USA

The BAKFlip MX4 is designed for truck owners who demand both security and functionality. Its flush, low-profile look enhances your truck's appearance while the robust aluminum construction and advanced sealing system safeguard your gear in the toughest conditions. Backed by a 5-year limited warranty.

Note: This cover does NOT fit trucks equipped with the Multi-Function (Split) Tailgate or RamBox bedside cargo storage system. For Ram 1500 without those options only.
