The BAK BAKFlip MX4 (GEN 3) fits the 2015-2019 GMC Sierra 3500HD 6ft 6in bed and delivers a hard folding tonneau with 22 percent stronger panels than the previous generation.
Product Overview
The BAKFlip MX4 is built from heavy-duty aluminum top panels and side rails, reinforced with high-density polymer cores for a 22 percent strength increase over the original.
A patented auto-latching system secures the cover on close, and re-engineered lock components improve resistance to forced entry versus GEN 2.
EPDM rubber perimeter seals and a 13 percent longer dual-action tailgate seal keep water out while preserving factory tailgate function.
