The BAK BAKFlip MX4 (GEN 3) fits the 2019-2026 GMC Sierra 1500 with the 5ft 8in Carbon Pro bed and delivers hard-folding security with a flush, 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 versus the original MX4. EPDM rubber perimeter seals and tight-fit clamps lock out weather between the cover and bed rails.
On your Sierra 1500, it sits flush with the bed rails for a clean profile, while the auto-latching system and re-engineered locks secure your cargo.
