## Overview

The BAKFlip MX4 Hard Folding Truck Bed Tonneau Cover is a premium, matte-finished aluminum cover designed exclusively for 2021-2023 Ford F-150 5'7" beds. It features an automatic latching system for ultimate security, supports up to 400 lbs of evenly distributed weight, and offers full bed access without obstructing the 3rd brake light or tailgate function. Engineered for durability and style, it protects against UV damage and scratches while providing a sleek, no-profile look. Easy to install and backed by a 5-year warranty with US-based support, the MX4 is America’s #1 selling hard folding cover for truck owners who demand both form and function.

## 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: Fit great, easy to install and great if you need to flip it up to utilize the entire truck box.
Review: Upgraded from the factory Ford trifold. This top is perfect. Fits excellent. Automatic tailgate opens and closes as it should with no interference. Had a major storm yesterday and the box was completely dry except for some water on the tail gate, which I expected. There is a small clearance at the tailgate to allow for the automatic tailgate release. You could adjust it closer if you need. I'm very satisfied. Looks so much better too.

## Questions & Answers

**Q: Does it fit a chevy truck? All I see is ford**
A: The BAK BAKFlip MX4 Hard Folding Truck Bed Tonneau Cover you mentioned, with part number 448339, is specifically listed as fitting the 2021 - 2023 Ford F-150 models with a 5' 7" bed.

Based on the information provided, it appears that this particular tonneau cover is designed and intended for Ford F-150 trucks, and there is no indication of it being compatible with Chevy trucks.

If you are looking for a tonneau cover for your Chevy truck, I would recommend looking for options specifically designed to fit your Chevy model and bed size. It's important to ensure that the tonneau cover you choose is compatible with the specific make, model, and bed size of your truck to ensure proper fitment and functionality.

**Q: where is the part number located.? I don’t see no white sticker on bottom and no box**
A: I can't help you.  I got a Bak Flip G2.

**Q: How durable is the MX4? Read many reviews of this tonneau cover denting easily.**
A: Its as tough as they come. I've had my 4 year old nephew standing on it and no flex at all. Plus its so easy to install and operate, hell my wife finds it easy to use. Its made with top notch materials and looks great on the truck. I had friends see mine and bought one just from sight. we love ours and have no issues with it at all. 
Its a solid buy!!

**Q: Will this fit a 2023 f150**
A: With a New Model Year F-150 it would be best to contact the manufacturer directly. Although they do reference it fitting 2021-2023. Mine is an Older Model and it fit correctly.

### ⭐⭐⭐⭐⭐ Review
*by G***O on 4 February 2026*

Far lighter in weight than the previous model I had installed on my f150. Same quality but much easier to fold back to utilize the entire space in the bed. Easy to self install and the quality of product make this a great option for covering the bed of your pickup.
