Product 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. .

This was a VERY easy install. Once the side rails went up it was smooth sailing. I have a drop in bed liner and didn’t have to do any trimming. That may not be the case for every drop in bed liner so be aware of that. The instructions were straight forward and there are plenty of videos to watch for visual aid. I also have a bed extender and it fits perfectly with the tonneau cover. I am very satisfied with the design and how it all came together, start to finish.

I purchased this cover last year and should have shipped it back immediately. It leaked water in the middle seam of the cover. It was a small leak so I didn't really notice it but over time it got worse. I contacted BAK customer service and explained the circumstances. I had to submit pictures and videos via email in order to prove it was a defect and that it was under warranty. Side note...you have to call them. It takes at least 8 days before anyone will respond to an email over there. So after a call and some paperwork they sent me a new cover, and asked me to keep the old rail system.
New cover arrives! I install it and it rained that day. It leaked in the middle, on the sides, and in the front. It basically leaked all over. Once again, I called BAK and provided them with video and picture evidence. They informed me that yes, it was yet another defect, and that the likelihood was low that something like that would happen twice in a row, let alone three times. So they sent me another cover... I installed the new cover and...go ahead...take a guess, it leaked. It leaked worse than the other two.
At this point I'm going crazy. I've installed covers like this before. The amount of time and money I had wasted on this thing is preposterous. For each defective cover, I had to tear off the cover, field destroy it and submit evidence to BAK that it was unusable to prove I wasn't reselling them to someone. So once again, I email photos and videos...I call and get someone I hadn't spoke to yet. We agree to try something new. They sent me a new cover, and new rail system to rule out the old rail system as the culprit. I also purchased special silicone and layered it under the new rails to block any water from coming in the sides (per BAK's recommendation). I also purchased a rubber seal that went on the tailgate as well. So, new bed cover, new rails, silicone under everything and a rubber gasket. There's no way it's gonna....
LEAK. It leaked in the same areas as the other three covers. There was no rhyme or reason for any of it. It leaked right in the middle at several seams in addition to the sides again. So...I call bak and they tell me that in order to get my money back I need to go through amazon, and have them contact BAK and they can work something out. It took another hour on the phone but they finally refunded me my original purchase amount.
I took that money and bought a Gator Trax retractable cover. I installed it once....not a drop of water get's in the bed of my truck. No special silicone, or gaskets...it just works. I will 100% NEVER buy another cover or product from BAK industries. I can see something failing every once in a while...but after 4 attempts on the same cover it isn't the archer...it's the arrow.
If you've read this far, save yourself the headache and get this https://www.amazon.com/gp/product/B01BKRZLYQ/ref=ppx_yo_dt_b_asin_title_o05_s00?ie=UTF8&psc=1
It might cost a bit more, but I promise you it's worth it to avoid the insanity that I had to go through.

Fits perfectly.
Warning: You do have to remove the factory rails on the box. The cover does come with a extension kit so you can reuse the rails BUT my rails didn’t want to come out and the bolts stripped out. I ended up cutting them out and couldn’t reuse the rail after. So if the rail is important to you make sure you can remove the bolts 1st before you purchase the cover.
