The BAK BAKFlip MX4 fits the 2020 GMC Sierra 3500HD 8ft bed and delivers a flush-mount hard folding tonneau with matte black finish.
Product Overview
The BAKFlip MX4 (GEN 3) is a hard folding tonneau cover built from heavy-duty aluminum top panels and side rails reinforced with high-density polymer cores. Panels deliver a 22 percent increase in overall strength compared to the original MX4.
A patented auto-latching system secures the cover when closed, while re-engineered lock components improve resistance to forced entry. EPDM rubber perimeter seals and a 13 percent longer dual-action tailgate seal keep weather out of your 3500HD bed.
