BAK 6ft 6in BAKFlip MX4 Matte Finish Bed Cover | 2019-2026 GMC Sierra 1500

The BAKFlip MX4 (GEN 3) fits the 2019-2026 GMC Sierra 1500 6ft 6in bed and delivers a flush-mount hard folding tonneau with a textured matte black finish.

Product Overview

The BAKFlip MX4 is a hard folding aluminum tonneau cover built with heavy-duty top panels, alloy side rails, and high-density polymer cores. Panel strength is increased 22 percent over the original MX4.

BAK's patented auto-latching system secures the cover the moment it's closed, with re-engineered lock components for added forced-entry resistance. EPDM perimeter seals and a 13 percent longer dual-action tailgate seal keep cargo dry.

The cover sits flush with the Sierra 1500's bed rails for a clean, low-profile look that maintains factory tailgate functionality in any position.
