With over one million units sold worldwide, the RealTruck® RetraxPRO MX tonneau cover returns with the strongest, smoothest, and most-refined release yet. Built for serious durability and everyday utility, the premium retractable truck bed cover delivers unmatched security, all-weather protection, and flexible cargo control—no matter where you’re trekking or what you’re hauling. At its core, the RetraxPRO MX features a durable double-wall aluminum slat surface engineered for superior strength and security. Designed to support up to 500 lbs. of evenly distributed weight, this bed cover offers confidence whether hauling gear below, on top, or both. A factory-grade matte black powder coat resists scratches while complementing your truck’s finish. Opening and closing the cover is effortless thanks to the exclusive CoreTrax™ sealed rollers and the key-lockable TraxLatch™ comfort handle. With infinite positioning, the TraxLatch system allows the cover to be held open in any configuration along the bed—and even lets you secure gear between the cover and tailgate for added versatility. Best of all, the cover opens and closes independently of the tailgate, so you can access your gear without dropping it. Engineered and tested for use in extreme conditions, the RetraxPRO MX performs reliably in temperatures from -40 to 180°F and up to 95 percent humidity. Specialty components resist freezing and binding, ensuring effective operation in all weather conditions. An all-new water management system seals tightly and channels excess moisture through integrated drain tubes, helping keep cargo protected and dry. A reinforced storage canister with fortified ends adds strength and durability, while updated packaging ships in a single box for easier handling. The RetraxPRO MX is assembled in the USA and backed by a lifetime warranty. Installation is quick and easy with the clamp-on rails—requiring no modifications and only 60 minutes of your time.
