Why the BAKFlip MX4?

The MX4 sits at the sweet spot between price and performance. Its aluminum panel construction provides a level of security and weather resistance that soft covers simply cannot match, while remaining more affordable than retractable options. The matte finish holds up against UV damage, and the integrated prop rod means you can carry oversized loads while still having partial bed protection. Multiple independent reviewers including Automoblog, RealTruck and AutoZone's buying guide rate the BAKFlip MX4 as the top hard folding tonneau cover year after year. It fits over 50 truck models and ships direct to your door with free shipping on orders over $250.
