The BAK BAKFlip MX4 (GEN 3) fits the 2020 GMC Sierra 2500HD 6ft 6in bed and delivers a hard folding tonneau with 22 percent stronger panels than the original MX4.

Install Difficulty: DIY Possible
Clamps to factory bed rails with included hardware; typically installs in 30-45 minutes with no drilling required.

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 strength increase over the previous generation.

A patented auto-latching system secures the cover when closed, and re-engineered lock components resist forced entry better than GEN 2. EPDM rubber perimeter seals and a 13 percent longer dual-action tailgate seal keep weather out of the 6ft 6in bed.

The cover sits flush with the bed rails in a textured matte black finish that blends into the Sierra 2500HD's profile.
