The BAK BAKFlip MX4 (GEN 3) fits the 2019-2020 GMC Sierra 1500 5ft 8in bed and delivers a flush, matte-black hard folding tonneau with 22 percent stronger panels than the previous generation.

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

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.

An auto-latching system secures the cover when closed, and re-engineered lock components improve resistance to forced entry over GEN 2.

EPDM rubber perimeter seals and a 13 percent longer dual-action tailgate seal keep weather out while preserving factory tailgate operation.
