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. Finally, the MX4 can hold up to 400lbs of evenly distributed weight and is backed by a 5-year, hassle-free warranty. BAKFlip MX4 is proudly made in the USA with globally sourced materials with a US-based support team. .

  • Worth the price
Great fit, install was fairly straight forward and the material and product construction is of high quality

  • Excellent tonneau cover!!!
Excellent fit and very high quality!! The overall look of this cover is awesome! I love the low profile and 100% bed availability if the need arises. A little pricey, but after receiving and installing the cover it’s worth every penny.

  • SWEEEET!
Easy to install, took me well under an hour. Good quality, really sturdy with some very nice features. One of my favorites which makes this hard folding cover stand out is that it folds up to an upright position parallel with the rear cab window and comes with braces on both sides to hold it there. This allows you to utilize the entire bed of the truck when needed. A lot of the other versions of this type I saw didn't have this so when you folded it back you would lose the functionality of about a foot or so of bed space. You get a truck for when you have to move things, you don't want to fool around with limiting your available capacity when you need it most. This is easy to install, easy to use, improves the security for items in the bed of your truck and allows you to retain the use of more of your bed space when needed. I would definitely buy this again. ... show more

  • Looks great, and good fit for 2020 GMC Sierra
The cover looks great and protects the contents of the bed. I haven't had a heavy rain yet, so I can't comment on the water resistance. I did wash the truck recently, and there was no water intrusion into the bed. I've used camper shells on past trucks, and this cover is much more stylish while offering just as much security. It was pretty easy to install - it took me about 2 hours. ... show more

  • Tons of damage and didn't keep water out of the bed of my truck
First off, the Amazon delivery person propped the box against my house when the box says not to do that. Then as you can see in all the pics, tons of damage to the cover. And maybe because the package was propped up and not flat, the back end doesn't lie flat at the tailgate. Struggled to get the cover to sit straight so there isn't any gap on the side of the bed. And also the parts that hold the poles under the cover if you don't prop it up to travel, are poorly made. One was snapped when I installed the cover. Plus I don't see this cover handling as much weight as advertised. Loved the idea of this cover but very disappointed in what I got. ... show more
