Features
- Locks the moment it closes: BAK's patented auto-latch engages as each panel closes, so there is no separate locking step. BAK says the Gen 3 lock parts were re-engineered to resist forced entry better than the Gen 2. To open it, drop the tailgate and pull the release cable.
- Sealed edge to edge: Revised EPDM rubber perimeter seals and tight-fit clamps close the gap between the cover and the bed rails, and on most trucks a dual-action tailgate seal, 13% longer than before, covers the tailgate. Drain tubes carry off water that reaches the rails. BAK's own sheet notes the cover is not airtight, so think weather-resistant, not sealed.
- Multi-layer aluminum panels: Aluminum top panels sit over high-density polymer cores on aluminum side rails. BAK says the Gen 3 panels are 22% stronger than the original MX4, and the closed cover is rated at 400 lb, evenly distributed.
- Folds to the cab, drive open: Fold the panels to the cab, strap the cover to the buckles at the bulkhead and drive with the bed open for tall loads. Flipped fully upright, prop rods hold it against the cab on rubber bumpers. BAK says it is the only hard fold that leaves your 3rd brake light visible in every position.
- One-person install: Click-in clamps hold the rails to your bed rails, with no drilling on most trucks, and one person can do the job. BAK rates it at 30 minutes or less (Level 1) and says the new click-in design cuts install time by 12%.
- The original hard-fold cover: BAK says the MX4 defined the hard-folding category and calls it America's best-selling truck bed cover. The Gen 3 version (model year 2025) sits flush with the bed rails and wears a textured matte black finish on every surface.
Description & Fitment
BAKFlip MX4 448135 fits the 2019-2027 GMC Sierra 1500 with the CarbonPro bed, 5'8" bed. Fold it against the cab and strap it down to drive with the bed open; BAK notes the 3rd brake light stays visible in every position. On this truck this version bolts into U-nuts behind the bed caps, which means drilling small holes in the plastic caps and two drain holes in the liner, and BAK puts the install at 30 minutes or less. BAK calls the MX4 America's best-selling truck bed cover, and the Gen 3 version adds re-engineered locks and a longer dual-action tailgate seal. Re-engineered prop rod clips hold it upright against the cab, and rubber bumpers protect the cab paint. Trucks without the CarbonPro bed take BAKFlip MX4 448130 instead. BAK backs it with a 5-year limited warranty.
Fitment & Compatibility
| Years | Model | Bed | Notes |
|---|---|---|---|
| 2019 | Sierra 1500 | 5'8" | New Body, w/ CarbonPro Bed |
| 2020-2027 | Sierra 1500 | 5'8" | w/ CarbonPro Bed |
Check your bed: measure along the bed rail from the bulkhead to the inside of the closed tailgate. This part is for the 5'8" bed on the 2019-2027 GMC Sierra 1500 with the CarbonPro bed. BAK's own brands list this box at 69.3" to 69.9" long, depending on the generation. Fit notes from BAK: with the CarbonPro bed (2019-2027 GMC Sierra 1500).
Not for: the 8' bed (BAKFlip MX4 448132), the 6'6" bed (BAKFlip MX4 448131), trucks without the CarbonPro bed (BAKFlip MX4 448130). 2014-2018 trucks with the same bed take BAKFlip MX4 448120. The 2019 Silverado 1500 LD and Sierra 1500 Limited keep the previous body and are not covered here.
About BAK Industries
BAK.
BAK makes hard tonneau covers. BAK bills itself as "America's #1 truck bed cover."
The range splits into BAKFlip hard folding covers (MX4, MX4 EZ-Lift, MX4 TS, G2, F1 and Fibermax) and Revolver hard roll-ups (X2, X4s and X4 TS). The MX4 is the aluminum-panel BAKFlip that BAK calls America's best-selling truck bed cover; the MX4 TS adds T-slot rails and the MX4 EZ-Lift adds a lift-assist system.
Authorized BAK dealer. Prestige Truck is an authorized BAK dealer, so what we sell is new and genuine BAK. BAK's warranty "is nontransferable and applies to the original purchaser of the BAK product only," and BAK requires warranty registration on file or proof of original purchase (a detailed, dated receipt) for warranty service. Your Prestige Truck order receipt is that proof.
Frequently Asked Questions
Will this fit my 2019-2027 Sierra 1500 CarbonPro?
Yes, if it has the 5'8" bed. Measured along the floor, that box is about 69.3" to 69.9". Measure along the bed rail from the bulkhead to the closed tailgate, and note it is not for the 8' bed (BAKFlip MX4 448132) or the 6'6" bed (BAKFlip MX4 448131). If you are unsure, send us your VIN and we will confirm.
What if my truck is not equipped with the CarbonPro bed?
Then this one is not the right part: BAK lists BAKFlip MX4 448130 for GMC Sierra 1500 trucks without the CarbonPro bed. This page covers the version without that option.
What changed with the Gen 3 MX4?
BAK lists stronger panels (high-density polymer cores, 22% stronger than the original MX4), re-engineered lock parts that resist forced entry better than the Gen 2, revised EPDM perimeter seals and tight-fit clamps, a dual-action tailgate seal 13% longer than before, re-engineered prop rod clips, and a click-in design that it says cuts install time by 12%.
Will it keep rain and snow out of the bed?
It is built to: edge-to-edge seals and tight-fit clamps close the gap to the bed rails, and drain tubes carry off water that reaches the rails. BAK's own install sheet says the cover is not airtight, so plan on weather-resistant rather than sealed. Clear snow and ice off before you open it; that is a warranty condition too.
How much weight can it hold?
BAK rates the closed cover at 400 lb, evenly distributed. BAK's sheet also says not to drive with objects on top of the cover or tie cargo to it.
Can I drive with it folded open?
Yes. Fold it toward the cab and attach the straps to the buckles at the bulkhead, pulled snug, and you can drive with the bed open. The cover must be secured at all points while the truck is moving; that is a condition of the warranty.
Installation
Install time
30 minutes or less (BAK's figure)
DifficultyLevel 1simple installation; one person
TypeBolt-on into U-nutsyou drill small holes in the plastic bed caps and two drain holes in the bed liner
Tools
- a 10mm open-end wrench
- plus isopropyl alcohol, drill, 7mm (9/32") drill bit, 22.3mm (7/8") drill bit and knife or cutting tool
Here's the short version. Follow BAK's install sheet (below) for your truck's exact clamp positions and settings.
- Fit the U-nuts. Pry the plastic bed cap away from the bed wall and slide five U-nuts into the openings on each side, each lined up with the bed-rail hole.
- Drill the mounting holes. Slip the hole drill guide between the bed cap and the bed, seat it in each U-nut, and drill a 7 mm (9/32") hole through the plastic bed cap; the guide keeps the bit off the truck bed. Thread the M6 bolts into the U-nuts, leaving them about 1/8" (3.18 mm) proud of the bed cap.
- Mount the rails and drains. Hang each side rail on the bolts by its slots, push it down and forward so the seals set on the bed cap, and tighten the bolts with a 10 mm open-end wrench. Stick the bulkhead seal across the cleaned bulkhead. Drill a 22.3 mm (7/8") drain hole through the bed liner at the center of each circular divot, outer liner only, then push in the drain hose and slide its collared end onto the rail drain.
- Prep the cover. Slide the two cover retainer clamps into the track under the cab end of the cover, one per side. Peel the liner off each gasket, stick it under a buckle end, and screw the two buckle ends into the pre-drilled holes on the front header panel with the screws and nutserts. Hand-tighten only; don't use a screw gun.
- Set the cover in place. Lay the folded cover on the side rails at the cab end and fit the retainer clamps around the rails. With the cover folded, clean the spots for the three cab bumpers and stick them 3.5-4" (90-100 mm) in from the side edges of the cover, so they touch only the glass and never paint.
- Unfold, adjust and check. Unfold the cover toward the tailgate and center it, loosening the retainer clamps to shift it if needed. Release each latch to check it engages the rails (the sheet shows how to adjust a slam latch), then re-tighten the retainer clamps.

For a non-handy person, this was easy to install. Only issue was the drainage tubes which were a bit more difficult to understand (but could have been due to my truck). A little pricey but so glad I went with hard cover that can also flip up to get full access to the bed.

I read a lot of reviews on this and other covers before purchasing this one. I was not disappointing! This cover is rugged, secures nicely to the truck and keeps the water out and everything inside nice and dry, and best of all, being able to close the tailgate with the cover latched in place. Easy to install...took me about 45 minutes by myself.

The railing clamps were especially tight. That’s good. The directions did not show how to remove the plastic end caps so that the clamps could be slid into place.

I wish I bought the MX2 instead.
I had an MX 2 installed on my 2017 Tacoma in January 2017. When I recently bought a 2023 Tacoma I wanted the BakFlip for it. The MX 2 is so much easier to install and it aligns with no issues. I had to keep adjusting the rails to improve the fit. The right side of the cover did not close all the way; there was a 1/4 inch gap. Part of the problem was the rubber seal improperly installed at the factory. I managed to peel it back and adjust it as it should have been.

Solid choice
So far has done almost all I would expect. Stays dry when closed up, and when folded up is out of the way to use the bed. Have only had this a few weeks at this point. Relatively easy to install, had to drill out for drains, which the vendor could have provided nipples for the hose to drain holes in bed.

As advertised
The MX4 works great. Fits great. I do get a very small amount of water intrusion but only going through the car was with very high pressure rinse that hits from many angles. The only knock I have is the manufacturer could do some clean up prior to shipping. Everywhere they drilled holes is full of aluminum chips on the cover. I am a manufacturer director and spent my career in machine shops. Annoying. They are sharp enough to cut or puncture if you done know how to handle shavings. Lazy manufacturing IMO. Lastly, the pull cables are a little slack on mine. Haven’t tried to adjust it yet.

Looks great, minor leaks, stripped screw
The cover looks great but there are tradeoffs over a hard cover. I do like being able to access the entire bed easily. The front seal needed extra work due to a spray on liner but it still let's in a little water especially from automatic car washes and very strong storms. My biggest gripe is that 2 screws holding the latch mechanisms were stripped. I only found them because most of the screws were loose and had to be tightened. And no, I didn't strip them. I really wanted to like this cover but in the future I'll try something different.

Expected a bit more for the price
First, watched the online video instructions for my year mode and make prior to starting. Small item, but 1/8" shims shown in the video were not included with my purchase. Second, both rubber bumpers that support the cover when in the folded position became unattached after 6 weeks without ever having the cover in the folded position. Third, both struts that are used to lock the cover in the folded open position are constantly vibrated from their holders and then hang down getting entangled in what ever cargo is being carried. Just a matter of time before they are broken off.

The Ford Maverick factory options are fine but the BAKFlip is heavier duty. The installation was easy and took an hour but I have installed one on my F350 previously. It may take a little longer for someone with no experience installing a bed cover. Instruction are easy to follow. The BAKFlip is popular so there are excellent videos of step by step instruction online. An advantage of the BAKFlip is it is more secure than a regular cover. It’s going to be hard for someone to break into my bed and steal anything.

Poor quality
The first backflip we received had a divet in the panel. They sent us a new panel that had the corner cover damaged and the screw pulled out. It was for a Long bed truck and it didn’t come with full length solid rails we had to add the extra 2’ which wasn’t easy and was annoying. Since we have been using it for over a month, 4-5 of the protective foam pieces have come loose and fallen off and we have tried to put some back on but they keep falling off. Overall this seems like a very low quality truck bed cover with components that can’t hold up to hardly any use or the outdoor elements. Very disappointed in this product.

I’m very pleased with the fit, finish and ease of installation. A couple of pieces were damaged in shipping and customer service replaced them quickly. The only improvement that I can suggest is a heavier duty box to ship it in.

Got the cover quickly. Install was pretty easy but I did read and watch videos before install. My 11 year old grandson, he did most of the work inside the truck bed, and my son assisted. So you know it was a straight forward install. Love the topper.

It leaks
Was initially impressed with the bed cover. Appearance is great, installation was easy. But after a rain, water pools in the middle of the cover and begins to leak in the middle of the bed. Ive had numerous bed covers (roll up/soft trifold/hard trifold) and they all leak and I understand that it is unavoidable. However, other bed covers have leaked towards the cab or at the tailgate. This one leaks right in the middle of the bed. For the price I cannot and would not recommend this cover to friends/family.

Great product that I nearly installed all by myself. Had to ask my wife to push down on the lid to secure the bolts. Other than that this was easy to install and works great. Minimal water crept in during the last rain. You might pay a little more but why not have the best.

I like the cover especially because it's a hard top. There still is leakage and some parts, like the seal, seem to be fragile. Mines popped off. I have to move it a little to make it lock. If I have to use my whole truck bed, it covers my whole back window. I do like the steak flush look. I like that it easily opens with the pull down. I also like the fact you can close it with the truck bed door open or closed. Overall I like it, but for the price, definitely wish there were some things that were better.

The Best Truck Bed Cover Yet!
In 2015, I bought my first BakFlip and transferred it to my second Ram 1500. Here in 2026, I bought my third Ram and decided to get the new BakFlip design and am glad I did. Very easy to install and it took me less than 30 minutes. I love the finished look - like it's from the Ram factory. I like that the folded panels are really secured in place when driving and won't get whipped in the wind plus it leaves room for maximum cargo space. The upgraded cable system for latching and unlatching is another big plus. They really designed a great product and I recommend it over all the others out there. . . well worth the money!

Poor Q/A inspection
While the cover looks good the quality of parts were defective. I had to call for replacement and repair parts twice. The cable to release the lip broke due to poor workmanship. I had to replace the latch myself after only 2 weeks. This is way overpriced for having to fix it myself.

Great utility, quality not as much
My wife had one of these on her 2010 nissan titan and it was perfect in every way. So when we bought a newer truck (2015 ram 2500) we wanted to get the same cover. Tonneau was shipped quickly, was packed well and had easy instructions. The fitment is perfect and the overall utility is great. I espec6like how it acts as a headache rack when fully up and out of the way. I've had this item for a year now and have had it opened and closed around 30-40 times. The wire for the section closest to the tailgate broke. Inside the latches the wire is looped and crimped on and it slid out of the crimps. So I had to buy new cable and fix it. Works like a charm now. I will say the other stock cables work well and have not broken. Other issue is the clips that hold the seal into the side of the tonneau keep popping out. They pop back in easily but it's definitely annoying and causes the seal to…

quiestionable longevity
I have this cover on a 2021 F250. I work in the construction industry and need to open it often. The corner pieces have fallen off and the coating doesn't hold up to medium use. The seal leak in various places. If this is something you rely on, I would consider other brands.

Needs Additional Latch set
Second fold from rear window needs a latch set. The joint raises and lowers after your speed reaches 70 mph and above. This can lead to water leaks at the joint. Contacted company, but would not fix problem or refund money. They said this is normal function of the cover. This problem is caused by the design of the aerodynamics of the truck with the Cab Air Deflectors. This is different from all other Chevy Trucks.

Disappointing Quality for the Price
For the price I paid, I wouldnt buy this cover again. The biggest issue is with the long-bed rails. They come in two pieces, but only include three mounting clips. Because of this, its very difficult to get the rails properly aligned during installation, and they never seem to line up quite right. The adhesive rubber bumpers have already started coming loose after being exposed to warm weather. Lastly, the cover gets extremely hot in direct sunlight. It becomes uncomfortable to touch and makes it painful to open when needed. Overall, Im disappointed. For what this cover costs, I expected better quality and a better-designed product. Now that its installed, I feel stuck with something Im not satisfied with.

Good but a few issues
Overall I am pretty happy with the MX4 cover. There were a few quality control issues I think with the cover, one of the end caps on the mid bar was not attached and was a bear to get reattached. One of the corner pieces is a little loose and doesn't seem to have the proper fit. But overall, was happy with the sturdiness of it, the ease of installation and the functionality. So far I have tested it in the car wash and through a couple good rains, and there is only two small leaks, at the front of the bed, between the bedliner and cover, I put a little foam strip in there to seal it up, it is mostly leak proof now, but a little bit of water will get into the bed at the front two corners. Other than those two spots, no leaks anywhere else.

With the longer bed this cover doesn’t allow you to transport with just one fold. Any suggestions. Also, any suggestions on making it less water resistant?

Install was a breeze and love the tonneau itself. Unfortunately the plastic end caps for the rails and the plastic rod holder were broken out of the box. Wish those pieces were as high quality as the rest of the cover.

Tonneau cover is nice - but damaged inside of packing
The cover went on well but once I installed it, I noticed the clip that holds the strap for locking into place in the folded position, was broken off. I found the broken piece in the packing material. The only real fix would be to send the whole cover back and I needed it for my truck. I guess I should have looked it over more closely when I removed it from the packing.

Clamps weren't right
The clamps don't seat well against the metal behind the cap rail plastic. So, they can't hold straight when closing the cover. I contacted support and they said to send a picture and over a week later I've gotten nothing back after additional email. Pretty disappointed that something so simple couldn't be resolved quickly. I have put backing material in place until they figure it out so I can at least use it. The tailgate seal was also not seated correctly so I had to take it off and reseat it. For such an expensive product they really aren't doing the small parts well.

Too short
Love everything about the cover except that it’s too short. It barely covers the edge of the bed at the front and just touches the tailgate. Seems about two to three inches shorter than it should be so it doesn’t keep the water out at the tailgate and it’s not very secure for theft.

Nope
It looks unfinished. The rubber molding on the sides creased up were it folds. I gave it some time n the heat to see if it would flatten and it didn’t. The corners by the cab looked unfinished. The installation of the rails was horrible, yes I did it right, and it still didn’t close and lock wo slamming it or lifting on the side rails get it to lock. For the amount of money it cost I expect much better. So I returned mine and went with another brand from another company. And am very happy now. No rubber flap edges. Easy install and locks every time. Yes: the return process was fast and easy, but I’m rating the product.

Bakflip MX4 Ram truck w/rambox
I’m very disappointed with this product. It leaks at both the front and rear, which defeats the whole purpose of having a bed cover/top in the first place. The instructions were also a major issue. I have a Ram with the RamBox bed, but the instructions provided were for a Chevy 1500. The installation is not the same, and it made the process much more frustrating than it needed to be. Had I known the product would not seal properly and that the correct truck-specific instructions would not be included, I would have chosen a different top. At this point, I honestly wish I could return it.

If you want a cover that does not leak look somewhere else. It has been installed correctly and it's still does not prevent water from entering the bed. . after a good rain the bed as water in it do not keep anything that is valuable in your bed.

Backflip MX4 Bed cover honest feedback
First of all, I don’t like to bring bad news, that being said, here it goes. Last year 2022 in may, I received my first MX4, it looked great! I had little trouble with installing it, about 30 mins I’d say. My issue is with the overall durability or thickness the bad cover aluminum, it dents so easily. One hailstorm and it looked like a golf ball. Ugh, that was just having it for a few months. The company was receptive to my concern, and sent me a “fiberglass” one to hopefully correct the issue. The next light hailstorm and it was another golf ball. I’m not sure if they sent me another aluminum one by mistake, or their fiberglass dents vs. cracks? It’s just a lot of money to ruin the look of your otherwise tough looking truck. Sorry Bakflip, you even tried to make it right by sending me another one, and still failed. Makes me feel a little sick.

Good but not perfect
Looks good, I like that it folds all the way for full bed access. One of the bumpers for when it is fully open blew off. Still leaks water inside. Could probably use to be made a little longer for more coverage over the tail gate. I was expecting better for the money I paid for this thing. I have a cheaper one on a different truck that leaks about the same. I going to try some extra gasket in places and hope for the best.
