The BAK BAKFlip MX4 (GEN 3) hard folding tonneau cover fits the 2015-2019 GMC Sierra 2500HD 6ft 6in bed and delivers flush-mount styling with 22 percent stronger panels than the original MX4.
Product Overview
The BAKFlip MX4 is a four-panel hard folding tonneau built from heavy-duty aluminum top panels and side rails, reinforced with high-density polymer cores for a 22 percent gain in panel strength over the previous generation.
Security comes from BAK's patented auto-latching system paired with re-engineered lock components that resist forced entry better than GEN 2. Revised EPDM rubber perimeter seals, tight-fit clamps, and a 13 percent longer dual-action tailgate seal keep cargo dry.
The cover sits flush with the Sierra 2500HD bed rails in a textured matte black finish.
