RealTruck states that the Gen 3’s polymer-reinforced aluminum panels provide approximately 22% more strength than the original MX4, while redesigned locking components improve security compared with the previous Gen 2 design.
22% Stronger Panels
One of the most significant upgrades to the BAKFlip MX4 Gen 3 is its redesigned panel construction.
The aluminum top panels are reinforced with high-density polymer cores, giving the new generation approximately 22% greater overall strength than the original MX4.
That additional strength helps provide a more substantial, durable surface while maintaining the low-profile folding design that made the MX4 popular.
The MX4 Gen 3 remains rated to support up to 400 pounds of evenly distributed weight across the cover.
400-Pound Weight Capacity
The BAKFlip MX4 Gen 3 can support up to 400 pounds of evenly distributed weight across the tonneau cover surface.
This gives the cover a strong, solid feel while adding another layer of protection for the cargo stored underneath.
The weight rating applies to evenly distributed weight and should not be interpreted as a single concentrated load in one area.
100% Truck Bed Access
One of the biggest advantages of the BAKFlip design is full truck bed access.
The MX4 Gen 3 folds forward panel by panel.
When you need maximum cargo space, the entire cover can be folded upright toward the truck cab and secured with the integrated prop rods.
This gives you 100% bed access without having to remove the tonneau cover from the truck.
