## Overview

The BAKFlip MX4 Hard Folding Truck Bed Tonneau Cover is a premium, matte-finished aluminum cover designed for 2019-2023 Chevy/GMC Silverado and Sierra 6'7" beds. It features automatic locking panels for enhanced security, full bed access without obstructing the 3rd brake light, and supports up to 400 lbs of evenly distributed weight. With superior scratch and UV resistance, dual drain tubes, and a 5-year warranty, the MX4 combines style, durability, and convenience for the modern truck owner.

## Description

The BAKFlip MX4 was the first matte-finished, hard folding cover to market, becoming America’s #1 Selling Hard Folding Cover in just a few years. Simply put, the MX4 just looks better than other covers. Its sleek no-profile appearance allows you to maintain the appearance of your truck, while enabling you to securely stow cargo in the bed. The MX4’s pioneering, textured matte-finish adds a premium look and feel while also protecting against UV damage, annoying finger print marks, and scratches. MX4 has everything you expect from a premium cover. The engineers at BAK Industries fine-tuned even the smallest elements of the cover, down to adding cab corner caps and rail-end cap, to extending a matte-finish throughout the cover’s side rails, clamps, and elevator bolts. The MX4’s integrated buckle system and automatic latching mechanism allows you to drive with the cover partially or fully opened without covering the 3rd brake light. For 100% bed access, simply unlock the cover from either side via its pull latches and fold the cover all the way up against the cab. From there, you can prop the cover in place by tightening two rods into the underside of the panel. For enhanced durability, the MX4 also features pre-molded, shock-absorbent bumpers on either side of the panel, protecting the folded panels from hitting the cover during turbulent driving. Rain or shine, the MX4 provides confident cargo storage that’s complete with dual drain tubes to divert water away from the truck bed, as well as full perimeter seals to help protect against water intrusion

Review: Love my BAKFLIP! I have a 2021 Chevy Silverado and it fit perfectly. Products came quickly during this holiday season and is easy to install with a You-Tube video. Hardest part is making sure you line it up correctly so it closes and locks properly. Little pricey but it’s worth it.
