The GMC Sierra Tonneau Cover by BAK, specifically the BAKFlip MX4 (GEN 3) Matte Black - '19-'26, is a premium upgrade for your truck bed, offering enhanced durability and security. Designed to fit the new body style of the 2019-2026 GMC Sierra (without CarbonPro Bed), this cover is perfect for those seeking a sleek addition to their pickup with a practical purpose.
BAK has taken the beloved MX4 and refined it further with high-strength alloy materials, including heavy-duty aluminum panels fortified with high-density polymer cores, increasing strength by 22% from the previous model. The GEN 3 model also incorporates re-engineered lock components that offer a tougher defense against forced entry along with BAK's auto-latching system that secures your cover effortlessly. Not only does this provide peace of mind for precious cargo but also adds a layer of resilience for adverse weather conditions thanks to improved EPDM rubber seals and a lengthened dual-action tailgate seal.

The BAKFlip MX4 is not just about strength and security; it also contributes to your vehicle's style. With a matte-black exterior that adds a subtle but striking accent, the MX4 fits flush with your truck’s bed rails and folds easily for full bed access or stands up seamlessly for a continuous streamlined appearance.
