Built For The Truck That Does It All

If your Silverado or Sierra HD is doing serious work, you need gear that’s just as capable, and that’s where the BAKFlip MX4 comes in. Built with heavy-duty aluminum panels and finished in a sleek matte-black coating, this cover doesn’t just look sharp, it’s built to take a beating. Whether you’re protecting tools from the weather or keeping weekend gear secure on the road, the MX4 delivers with all-season protection and a strong, low-profile design. It folds up easily when you need full bed access, and locks down securely when you don’t. The dual-action tailgate seal lets you open or close the tailgate without touching the cover, adding a layer of everyday convenience. It installs without drilling, so your truck bed stays clean and unmodified. For drivers who want durability without over-complication, this cover is the kind of upgrade that earns its keep every mile.

Engineered For Strength Without Sacrificing Simplicity

The BAKFlip MX4 is a hard-folding tonneau cover designed for 2020–2025 Silverado and Sierra 2500HD/3500HD trucks with an 8-foot 2-inch bed. Made from aircraft-grade aluminum, its panels are lightweight yet tough enough to support heavy loads when closed. The matte-black finish provides resistance to scratches and UV damage, while giving your truck a clean, uniform look. Built-in seals and hinges offer solid protection against rain, snow, and dust, making it a year-round solution for work or daily use. The cover mounts using a no-drill clamp system and includes a dual-action tailgate seal, so you can operate the tailgate freely with the cover open or shut. When full bed access is needed, the panels flip forward and secure near the cab without blocking rear visibility. Note: This model is only compatible with 8' 2" beds and will not fit dually models or trucks equipped with factory utility rails or storage boxes.
