The BAK BAKFlip MX4 (GEN 3) fits the 2020-2026 Chevy Silverado 2500HD 6ft 9in bed and delivers a flush-mount, hard folding tonneau with matte black finish.
It locks automatically when closed and seals tight against the elements.
Product Overview
The BAKFlip MX4 (GEN 3) is a hard folding bed cover built from heavy-duty aluminum top panels and side rails. High-density polymer cores reinforce each panel for a 22 percent increase in overall strength over the original MX4.
Re-engineered lock components and BAK's patented auto-latching system improve resistance to forced entry. EPDM rubber perimeter seals and a 13 percent longer dual-action tailgate seal keep water out of the 6ft 9in bed.
The cover sits flush with the bed rails for a clean profile on your Silverado 2500HD and maintains factory tailgate functionality in any position.
