Here is the BAKFlip FiberMax for the 2014-2018 Chevrolet Silverado 1500 and GMC Sierra 1500, sized to the 5'8" bed. Two things set it apart: EPDM rubber hinges and outer rail seals, and textured gloss-black FRP top panels on an aluminum substructure. It clamps to the bed rails with no drilling, using BAK's clamps plus a stake pocket clamp at the tailgate end. Fold it once for two-thirds of the bed or again for all of it. The 6'6" bed takes 1126121 instead. BAK backs it with a 3-year limited warranty.

Check your bed: measure along the top of the bed rail from the bulkhead to the inside of the closed tailgate. This cover is for the 5'8" bed.
Not for: the 6'6" bed (1126121); the 2019-2027 Chevrolet Silverado 1500 (1126130). Each of those has its own BAKFlip FiberMax part number.
BAK Industries makes hard tonneau covers for pickups, among them the BAKFlip hard folding covers and the Revolver roll-up line. BAK's install sheets and customer service come from BAK Industries in Springfield, Missouri.
The FiberMax is the BAKFlip with textured FRP top panels on an aluminum frame, rated at 300 lb with a 3-year warranty. The F1 shares the FRP look with a foam core and a 400 lb rating, and the G2 uses solid-core aluminum-skinned panels.
Authorized BAK dealer. Prestige Truck is an authorized BAK Industries dealer. BAK's warranty is for the initial owner who buys the cover, and BAK states: "Warranty registration must be on file and/or proof of original purchase (detailed and dated receipt) required for warranty to be effective." Keep your order confirmation; contact us for registration help.
Yes, if it has the 5'8" bed. For the 6'6" bed (1126121), choose that part instead. Measure along the bed rail from the bulkhead to the closed tailgate, or send us your VIN and we will confirm.
Yes. BAK's sheet says no bulkhead seal is needed with a drop-in bed liner, and the drain tubes can run behind the liner.
Both have textured gloss-black fiberglass-reinforced polymer (FRP) tops. The F1's panels have a high-density foam core, are rated at 400 lb and carry a 5-year warranty. The FiberMax uses FRP top panels on an aluminum substructure, is rated at 300 lb and carries a 3-year warranty.
It is built to. EPDM rubber hinges and outer rail seals keep most water out, and an internal channel sends what gets past them out through drain hoses. The tailgate seal is a conventional one, so close the tailgate before the cover. BAK's install sheet notes the cover is not airtight, and clearing snow and ice before opening is a warranty condition.
BAK rates the closed FiberMax at 300 lb, evenly distributed. Its install sheet also says not to tie cargo to the cover or drive with objects on top of it, so treat the rating as a measure of strength, not as a roof rack.
Yes. Folded once, the nylon buckle straps hold it; folded against the rear window, engage the prop rods. BAK's warranty requires the cover to be secured at all points whenever the truck is moving.
Here's the short version. Follow BAK's install sheet (below) for your truck's exact clamp positions and settings.

High quality product. Great functionality and easy install.
I bought this product a few weeks ago and it's great. No leaks, secure and no noise. It was an easy installation. Nice appearance.
this product was easy to install and provides a near watertight secure cover on the bed. With all its foldability it gives you full bed access. Pricy but worth it.
I purchased my First BAKFlip 13 years ago and it was still in perfect shape when I traded vehicles recently. I purchased the newest version of the same product and it's EVEN BETTER! Now, the tailgate can open and close without lifting the last part of the cover. The durability and looks of these covers lasts for many years. I DO RECOMMEND while it is still new you may wish to put either a coat of graphene sealant or other UV protector on it as the black does bake in the sun. My first one still worked great and looked ok, but it had faded to a matte finish beginning after about 5 years of sitting outside. I would not buy another brand.
I am very pleased with your equipment. It was easy to install. It looks great. Thank you ....
It's a great product that is very easy to use. Ideally, it would either be 1 1/2" - 2" longer or the instructions would be very precise on where to place the very front of the tonneau cover and insulation strip so that you don't have to redo the insulation strip. It seems counterintuitive that the insulation strip and cover need to be set as far towards the back as possible so that the cover barely covers the truck bed. To make it fit, you leave 1 1/2" of the front railing exposed which you would expect to be covered for aesthetic looks and less chance of leakage.
I love the cover, but when you drive with it partially open strapped in place there is a sharp edge that rubs on the outer weather stripping. I filed the sharp edge and added some additional weather stripping.
Great product. Nice finish
Overall it’s a good cover. I used it in the folded position and it scratched pretty easily.
Excellent
Very sturdy
The install was pretty straightforward and took under an hour. Super happy with security that it provides, protecting the bed contents from theft. I took it through an automatic car wash day 1, and was impressed. There was some water intrusion in the corners, but it was very minimal. We took a road trip from Texas to Florida and encountered a nasty thunderstorm. I'd say the bed was about 90% dry. Super satisfied with the performance.
very nice looking and easy to install
Product looks great. Install a little more difficult but got through it.
Very nice and solid cover
perfect fit will help out on objects staying put, not sliding around in transit
Thumbs up !!
installed properly... but does not create a seal or even close to a seal. I'll need to add third party gasket material.
I reviewed and actually talked to people in parking lots of restaurants and shopping and asked them about their tonneau tops. The only one who was 100% satisfied with their product was the BAKFlip owner. It is a solid cover that clicks into place and locks securely. It is not completely waterproof but with the soft mattress I purchased with it any water stays below in the ridges of the bed cover. I highly recommend this product...you get what you pay for.
I’ve had the Bakflip tonneau cover on my 2019 Ram 5.6 bed for about 6 months now, 3 months in FL and 3 in MI. So far no complaints. My gas mileage improved by about 3 mpg (5.7 hemi). Very happy with this product, but it’s not cheap.
It’s about 80% water proof. Some leaks on the sides from standing water that “pools” up, but not bad at all.
Delivery was great; packaging was superior; data plate (box) info was perfect for warranty registration purpose; instructions were easy; installation (even for 70 year old) was fast & simple; alignment, sealing & mechanisms were true; ease of utilization is exactly right for me.
Love the Bakflip cover
Very pleased!
Fantastic hard cover. Easily a huge upgrade from vinyl and installation was a breeze. There is a fantastic video that walks you through step-by-step how to put it on, and it took under an hour. The ability for the cover to fold back in sections and still stay secure is a major plus. I love how the black gloss matched my paint very closely, and even my wife commented on how much better the truck looks. If you’re gonna spend tens of thousands of dollars on your vehicle, then why not invest a little bit to keep the items in the back secure, while also looking great.
Easy to install and use. Love the low profile look.
Awesome cover and easy install but missing some hardware.
It does the job
New mounting rails, eh, fibermax is great, had the older aluminum/ mix top it warped, new Fibermax is far better
An amazing cover but allows too much water in.
Just perfect!
It was delivered and within an hour it was done. It helps if your wife helps set the tonneau in the tracks. It lined up and works just like they said it would, AWESOME
This is my second cover I've installed and they are great. Easy to install, takes less then an hour. Looks great when completed and is secured. Maintenance is very easy and I can see this will last a long time. You can't knock this cover, well built.
This is my third backflip. Great product.
This is my fourth Bakflip, I really like the way they look
Put it on my 2018 honda ridgeline. Was very easy to install. Does leak a little when it rains, but nothing to complain about. Very good cover. On the ridgeline, you about 3 inches in the with of the bed because you need to install additional rails to install the cover. The directions for this were a little confusing. Other than that, no complaints.
Installation was simple Seems rather watertight. Haven’t noticed any water in bed.
Great build and quality. I don’t regret buying this one bit!
Installation was very easy. Looks great and folds open all the way to the glass, real easy. Solid. Highly recommended.
Works great looks great and easy to install.
Great item....no complains
When you roll it up, the pieces that hold the panels together come out. This results in the cover not sitting flush until you puts them back in place. A simple pin through teach one would prevent this from happening. Buy a roll of flex tape if you want it to be waterproof.
Good service and price are great
Second bakflip for me. Great cover.
Good looking cover and great price. Free Shipping ,you can't beat that.
The install was far easier than the instructions indicated. It's obvious that the instructions weren't updated for the 2024 Ranger because it has parts that aren't listed on the instructions and it goes together easier once you figure it out. It fits well, though I'm not sure its entirely waterproof. Time will tell. The look is outstanding and all I had hoped for. We'll see if the rubber seals hold up to the weather any better than the leather of most covers. That will be the real test. It's not year one I'm concerned with, it's years three through five.
Seems to be well made attractive cover that was very easy to install.
Cover is well made and awesome appearance to any truck. Install was a bit tricky but after watching videos, was easier to understand.
Excellent product that is well built and sturdy. Looks amazing and is well put together. It was very simple process to install and fits perfectly.
Good product as advertised
easy to install,gives my truck a whole new look
Fast shipping and well packed. This is our 5th Bak tonneau cover.We don’t worry about anyone breaking into it. Well built and versatile for hauling objects.
No leaking, had it installed in a half hour, looks awesome, and gave me 1 1/2 miles per gallon.
Great cover but was missing a few things for the installation and which I had to go to the hardware store or else I would of rated it a 5*
Easy install and fit perfect. I definitely recommend this cover for anyone looking to add a smooth look to their truck.
Looks great. Easy to install.
very happy with it
Overall a nice product and easy to install. Have drove through a heavy rain storm for few hours and had minimal leaking around a few edges. If your tailgate locks it's nice to be able to lock all your items in the bed. I installed it alone and wasnt that difficult, maybe an hour.
Real easy installation, after heavy torrential rain only one small leak by tailgate. Would highly recommend.
Easy to install, beautiful, durable and it looks great. Very good job. You toe the line. Sincerely
Installed the Fibermax without a hitch on my 2016 Ram 2500. And fits perfectly.
Really like this cover. Nice and Solid. I really like the sleek look, the versatility of it and the fact that each panel clicks in solid. I reccomend it.
This cover has exceeded my expectations. It was easy to install, although I did snap one of the bolts in the process, so the bolts could be a bit stronger. The cover fits the 6' bed of my 2017 Toyota Tacoma perfectly, and opens and closes with ease. It withstands the rain, snow and ice here in Maine. It has a great seal, and is essentially waterproof - the only time a bit of moisture got in was during a six hour drive on highways through a pouring rain. Otherwise, it is watertight. Best of all, it looks great. Couldn't be happier.
The video and instructions don't really explain how to strap down when cover is completely opened. The knobs to tighten the hinge receptor when wanting to prop up cover keep coming off. I've tried a few things to address that, will see if it works Beautiful Tonneau cover and easy to install.
Great deal. Easy install.
I will update this reciew after i receive my replacement cover. Many issue in receiving 1st, having to reorder.. received it and it does not fit properly. Spoke with CS Manager John and I am supposed to get a new unit. Still waiting, holiday shipping "may" have delayed the replacement. I must say customer service has been great, when you can get them on the phone. Very poor follow up though.
had to put a wood shim 1/4 inch shim down the length of the rail..they don't make it yet for the 2017 titan..but with the wood shim fit perfect...put these on 5 truck of mine already..great product..this top fit for 2015 titan an below...will fit the 2017 with that small shim
My BakFlip was easy to install and looks great. More than happy with this cover.
Fairly easy to install and it looks great on the pickup. Been noticing an almost 2mpg jump on they highway mileage too.
This item was extremely easy to install and very easy to utilize. Highly recommend this product.
This is my second BAKFlip (bought for a new truck). Installation was easy and I like the look of the fibermax over the earlier versions.
Cover looks great, easy to install, drove in a bad rain storm for 75 miles with just a little leakage but nothing got wet.
The cover installed in under 30-mins and looks great. The instructions were simple to follow. An extra set of hands to install the rails is helpful to ensure the cover fits well. Nice tight fit will keep dust and water out.
Great appearance, easy to install, well built, extremely satisfied and would recommend to anyone!
I think these covers are great. Very easy to install - they are expensive though. Very easy to flip up and have access to your entire bed. Not completely waterproof, but I didn't expect it to be. Not because of the cover, but all the other spots water can get into the bed, mostly around tail gate. Not much, just a little, even after a torrential downpour or car wash. I am completely satisfied with this cover. Exactly what I wanted.
Second Bakflip I have owened they work great and look good on the truck
The cover fit perfectly to my truck. I wish the drainage system was engineered better but it will suffice. Overall I'm happy with my cover.
I put this on in about 45 min with my wife help. be careful with the back seal, mine come loose in just a few days. they did send a replacement.
I love this cover! I'm a cinematographer, and it keeps my equipment and lights perfectly dry, even in crazy monsoon rains. Yet, I can still utilize my full bed space and keep my bed extender in the back without having to remove anything. I can store my equipment in the back and travel with it all locked up, or I can flip the cover open and film commercials for other trucks right from the bed while someone else drives. It's even better than I anticipated, and I couldn't be any happier!
Overall great product! Real easy to install, took about 45 min to install the cover with the BakBox option, The supplied weather stripping seals tight, rained for 4 days after I installed and no water leakage into the truck bed at all, even driving at highway speeds in heavy rain.
Delivery was fast, received it on the third day. Easy to install with the helpful manual instructions. Looks great and serves the purpose. I'm loving it!
I had 3 installed by a professional shop. All 3 leaked so bad everything got soaked. Couldn’t been any worse not having a cover at all. They all leaked at the rubber joint that folded and also ran down the wire you pulled to fold the cover. 3 new covers = 3 leaking covers.
My BAKFlip FiberMax looks great. Glad I bought it. My last cover, won't mention the brand, made my back window vibrate really bad, on the highway. Don't have that issue, now. Great product.
It’s a very nice cover but I think it should have been a little longer. It’s as far back on the bulkhead as it can go and the tailgate barely touches the rear seal.
My cover fits perfectly and was able to install fairly easily, but the instructions could be confusing and I was missing a couple of screws for tie downs.
overall I love this cover. It does leak some water near the center of the cover, but overall it stays pretty dry in the bed. Installing the clips/buckles that mount near the cab was an absolute joke. Shards of metal inside the screw holes prevented the screws from threading all of the way through. Had to drill them out and pull out any metal shards that were interfering.
Product has been pretty great so far. I just wish it had the ability to close the tailgate with the bed cover down.
I'm very happy with my bad box cover
Fits my 2014 Tundra great. Looks very nice.
I have no issues with my cover. It looks good and goes well with the truck. It leaks a little but I can live with that.
Sorry I had to return it because it did not fit my truck
In Step 1 of the instructions, there was no mention of where to place the front weather strip on the rail. When I first installed it, it was too far front, resulting in the back strip not overlapping the tailgate. I removed the cover, peeled up the strip, moved about 1.5" back, and reinstalled the cover. It was still too short. Now I nave to get more adhesive to move the strip a 3rd time to get the cover to fit. Instructions should have said to put the initial strip down at the closest edge to the bed. Once I fixed this, the cover is great.
Pros: Easy to unpack, organize, and get set up Light enough for one person to install alone Looks Fantastic Mostly waterproof Strong Easy to operate once installed Cons: Really bad installation instructions Parts came assembled backward (clamps) It takes a LOT of adjustment to get it right on the bed NOT a perfect (or even very good) fit Weather strip and foam peeled off on first day Bottom line: Very good product for the money and the level of engineering that goes into the design, beef up the small details! I shouldn't have to re-glue and reinforce foam and weather strip - this really ticks me off for the money I paid. Also, the fit should be a lot better, I have a standard short bed and this is a little too short to fit - why? I like the sturdiness and look of the product and am pleased with the water resistance (now that I replaced the foam and weather strip) - either drop the…
I have a fleet of trucks and I routinely buy BakFlip covers for them. My most recent purchase was a disaster and disappointing. The cover was shipped with one rail too short. Getting the correct part was nearly impossible. The service people were rude and non responsive. They finally shipped a complete cover kit instead of simply the single part that was needed. We had to then hassle with the whole new kit, then send everything back (minus the single part we actually needed) Terrible service, terrible attitude of service staff. The covers have been great but you better hope you don’t have any issues because they are incompetent and rude to work with.
I purchase this cover for a camping trip, I received this Back flip just in time to install and hit the road. What I didn't realize is an attached paper in the instructions telling me that if I didn't register online for the warranty within 2 week I would lose all warranty. So- on my trip I started having problems with the locking latch and the cable that you pull to open a section of the panel that flips. What I noticed is a small 2 or 3 inch aluminum section that is screwed into the aluminum panel, this panel has 4 set screws attached to keep the cable release stretched tight and locked, but when you bull the cable to open the panels are locked shut, the set screws are stripped out in the aluminum and are laying in the bed of the truck! I have a total of 6 set screws that fell out and you can't re-install because of the aluminum being stripped out. So the only way to fix this is…
It's solid and was fairly easy to install. I have a 2022 Silverado w/5.5 ft bed. Since it is 1.5" short in my opinion, it leaks, even under a light rsin. I adjusted it so that it covers the tailgate but also still butts up to the front of the bed. I readjusted my gasket to stop it but it doesn't. I really got it for security if I have stuff in the bed. For that, it works well.
Very sturdy. Looks GREAT. Probably keeps your stuff safe in your tonneau, but let’s a good bit of water in when it rains. Overall pretty happy but main reason for purchase was to keep things (golf clubs) dry.
Fit and worked perfect but had a small hole on the cover
