The BAK BAKFlip MX4 (GEN 3) fits the 2019-2026 Chevy Silverado 1500 6ft 6in bed and delivers a flush-mount hard folding tonneau with a matte black finish.
Product Overview
The BAKFlip MX4 is a hard folding tonneau built from heavy-duty aluminum top panels and side rails, reinforced with high-density polymer cores.
Panels deliver a 22 percent strength increase over the previous model. A patented auto-latching system secures the cover the moment you close it.
On your Silverado 1500, EPDM perimeter seals and a 13 percent longer dual-action tailgate seal keep cargo dry while preserving factory tailgate function.
