BAK BAK-448310 BAKFlip MX4 Hard Folding Tonneau Cover Matte Finish

The BAK BAKFlip MX4 (Part #448310) is a premium hard folding truck bed tonneau cover built for truck owners who demand security, durability, and all-weather protection without sacrificing style. Engineered with heavy-duty aluminum top panels and side rails reinforced with high-density polymer cores, the MX4 delivers a 22% increase in overall strength over the previous generation—making it one of the toughest folding bed covers available.

Key Features:

• Heavy-Duty Aluminum Construction: Alloy-based top panels and side rails with high-density polymer cores for exceptional rigidity and cut resistance
• Patented Auto-Latching System: Automatically secures the cover when closed; re-engineered lock components provide enhanced resistance to forced entry
• Superior Weather Sealing: Revised EPDM rubber perimeter seals and tight-fit clamps prevent water seepage between the cover and bed rails
• Dual-Action Tailgate Seal: Extended tailgate seal allows the cover to be operated with the tailgate in either the open or closed position
• Matte Black Finish: UV-resistant matte finish panels protect against scratches, scuffs, and sun damage for a sleek, low-profile look
• 400 lb. Weight Rating: Rated to support up to 400 lbs. of evenly distributed weight
• 100% Bed Access: Fold the panels toward the cab for full, unrestricted access to the truck bed
• Pre-Molded Bumpers & Prop Rod Clips: Die-cut, shock-absorbent bumpers and secure prop rod clips enhance panel operation and longevity
• Flush Mount / No-Drill Install: Near-flush, inside-mount design installs without drilling using standard hand tools
• 5-Year Warranty: Backed by BAK's 5-year limited warranty against manufacturing and material defects

The BAKFlip MX4 hard folding tonneau cover combines sleek aesthetics with serious performance. Its low-profile, flush-mounted design integrates cleanly with your truck's bed rails, while the robust aluminum panel construction resists forced entry far better than soft-folding alternatives. Whether you're hauling gear through rain, snow, or sun, the MX4's all-season sealing system keeps your cargo protected.
