BAK Industries BAK-448441 BAKFlip MX4 Hard Folding Tonneau Cover Matte Black Aluminum

The BAK Industries BAKFlip MX4 (GEN 3) is a premium hard folding truck bed tonneau cover built from heavy-duty aluminum panels and side rails with high-density polymer cores. This next-generation design delivers a 22% increase in overall strength compared to the original MX4, making it one of the most durable folding covers available. Its flush-mount, low-profile design sits level with the truck's bed rails for a clean, factory-integrated appearance.

Key Features:

• Heavy-duty aluminum construction with a matte black finish offering superior UV and scratch resistance
• Supports up to 400 lbs. of evenly distributed weight on top of the closed cover
• Patented auto-latching system automatically secures the cover when closed, with re-engineered lock components for improved forced-entry resistance
• EPDM rubber perimeter seals and tight-fit clamps create a watertight barrier between the cover and bed rails
• Dual-action tailgate seal — 13% longer than the GEN 2 — maintains factory tailgate functionality whether the cover is open or closed
• Folds toward the cab for complete 100% bed access; secured in the open position with extra-strong prop rods
• Integrated buckle system holds the cover securely in the folded position at highway speeds — no straps or bungee cords needed
• Injection-molded latch housing for long-term durability and smooth operation
• No-drill, clamp-on installation using included tight-fit clamps — most installs completed in 30–45 minutes with basic hand tools
• Compatible with or without factory utility track/deck rail systems
• Manufactured in Missouri, USA

The BAKFlip MX4 GEN 3 is backed by a 5-year warranty against manufacturing and material defects, giving you long-term confidence in your investment. UPC: 192631044871.
