Product Features
F150 5.5ft Bed BAKFlip MX4 TS Hard Folding Tonneau Cover Features:
Fits F150 with 5.5ft bed
Heavy-duty aluminum panel construction
Matte black finish resists scratches and UV
Integrated T-slot rails for rack compatibility
Folds forward for full bed access
Low-profile design sits nearly flush with bed
Supports over 400 lbs of cargo weight
Weather-resistant seals and end caps
Integrated drain tubes keep bed dry
Latch system allows easy open and close
Includes prop rods for upright positioning
Clamp-on installation, no drilling required
Hard-Folding Protection with Built-In Utility
If you're looking for a tonneau cover that does more than just keep your truck bed sealed, the BAKFlip MX4 TS for the 2021–2025 F150 is an upgrade worth considering. This version takes everything that makes the original MX4 a bestseller: like its strong, low-profile aluminum design and weather-tight sealing, and adds integrated T-slot rails that let you run racks and carriers without compromising the cover's function. That means you can haul bikes, kayaks, ladders, or even a cargo basket above the bed, while still keeping tools or gear protected underneath. It’s the perfect balance of rugged utility and everyday practicality, especially for folks who use their truck both for work and weekend adventure. Compared to soft covers, the MX4 TS offers far better security, more structure for hauling, and a finish that stands up to weather, impacts, and UV exposure over time.
Built Tough and Installs Fast
Opening and closing the MX4 TS is as simple as dropping the tailgate and pulling the rear latches. From there, it folds forward in sections and can be secured in the upright position with built-in prop rods. It gives you full access to the bed when you need it, without blocking the third brake light. The aluminum panels are lightweight but durable, rated to support over 400 pounds of evenly distributed weight. And with rubber bumpers and weather seals all around, water stays out, and your cargo stays dry. Installing the cover is quick and tool-free thanks to a clamp-on rail system that requires no drilling. The entire setup is proudly assembled in Missouri and backed by a five-year warranty. Whether you're gearing up for your next road trip, hauling equipment to the jobsite, or just want to keep your bed dry and secure, the MX4 TS gives you the flexibility and toughness your F150 deserves.
