BAKFlip F1 Tonneau Cover Operation Animation

The BAKFlip F1 tonneau cover delivers top-of-the-line truck bed protection and a tough, stylish look. This heavy-duty, quad-fold cover keeps your truck bed and cargo dry, cuts down on wind drag to improve your fuel mileage, and allows for full truck bed access without having to be removed. And because this tonneau mounts inside of your truck bed side rails, you get a low-profile look and you can still use your stake pockets to mount accessories.

Convenient Folding Design

One of the BAKFlip F1's most attractive features is that it can be folded all the way up and remain securely positioned on your truck while you are driving, even at highway speeds. This means that you can haul large cargo without having to completely remove the tonneau. Simply unlatch each of the panels, fold them one on top of the other, and flip them back so that they sit upright against the cab of your truck.

BAKFlip F1 Tonneau Cover Tonneau Cover Prop Rod

Then flip up the prop rods that are attached to the tonneau's frame rails, slide the brackets on the cover down over the rods, and tighten the knobs on the brackets to secure the upright cover in place. Rubber bumpers on the cover prevent it from marking your cab or scratching the glass of your rear windshield. When the tonneau is in this position, your vehicle's third brake light will remain visible.

If you want to maintain visibility out of your rear window, you can secure the folded panels of the cover without propping them up against the cab using the tie-down straps and buckles included with the cover. Just fold up the first 3 panels of the cover, leaving the panel closest to the cab latched in place. Make sure both buckle clips are inserted into the buckle ends on the front header panel of the cover and adjust the straps to ensure the cover is secure.

Simple, One-Person Operation

The F1 is easy to operate. To unlatch the rear panel, drop your tailgate and pull either of the 2 release cords located along the bottom corners of the panel's housing. Either cord will release both of the integrated latches so that you can lift up the panel. To unlatch the second, third, and fourth panels, pull the easy-to-reach release cords built into the corners of those panels. As a safety measure and to help you get to your gear in the dark, the F1 includes emergency release handles on both sides of your truck bed that glow in the dark.

To close the cover, simply fold the panels back down. Each panel will securely latch back into place under its own weight. When your tailgate is closed and locked, no one will be able to get in to open the cover, thus safeguarding your truck bed and its contents. The fiberglass-reinforced polymer construction will also prevent anyone from peeling the cover up at the sides or cutting through its center, ensuring additional security.

Heavy-Duty Construction

The BAKFlip F1's rugged construction makes it a great match for your truck, no matter what you do while at work or play. It's strong enough to hold up to 400 lbs of evenly distributed weight when it's folded down, so it can support your weight if you sit or stand on it.

Each 5/8" thick, fiberglass-reinforced polymer panel has a sturdy aluminum base with an insulated core that is made of top-quality, closed-cell foam to create a strong, heavy-duty cover. The polymer construction also ensures that the F1 stays cooler than an all-aluminum tonneau. The black powder coat finish with hair cell texture on top of the panels offers superior resistance to dents, dings, and harsh UV rays.

The frame rails are constructed of aircraft-grade, rustproof aluminum and have a sleek black, corrosion-resistant powder coat finish. And scuff-resistant, semigloss black rubber seals run all the way around the cover to help to keep water out of your bed. If any water does seep through, it will run along the gutter system that is built into the frame rails and will then exit through drain hoses that install behind your cab.

Glass-filled nylon latches in heavy-duty, injection-molded housings add to the F1's rugged design and ensure long-lasting, efficient operation. Flush hinges prevent ice and water from building up on the cover.

Easy, No-Drill Installation

Installing the F1 is simple. All you need is a wrench, and you don't have to do any drilling. The tonneau's frame rails clamp to the inside of your truck bed side rails to create a base for the cover. The included bolts secure the front hinge rail to the frame rails at the cab. Slotted brackets on the hinge rail allow the bolts to shift in case you need to adjust the cover to achieve a snug fit.

Very good product, glad I made the purc hase!

by: Jeff03/23/2017 One Year Later

Fit great for a 2015 Tacoma with 5 ft bed. No problems after one year.

by: Michael02/13/2024 One Year Later

It is a horrible cover, it leaks, it is way to heavy, parts already starting to fail.

by: Stephen01/30/2024 One Year Later

Great cover, easy to use. The only issue is that some water will leak into the bed especially near the corners.

by: Dan05/15/2019 One Year Later

No issues, easy to install, folds up nicely when I need the bed space, no water/rain leaking. It’s nice to conceal/protect cargo

by: Arturo03/08/2022 One Year Later

Easy to install. Secured and weather protected cargo is a comfort. It looks great on my truck. I'm very pleased with the product. I recommend it.

by: Thomas05/04/2021 One Year Later

It is a strong and durable cover but it is VERY heavy. I wish I got the lighter version.

by: Sean02/22/2022 One Year Later

If you want a cover that is secure and leaks this one is perfect. If it rains you are guaranteed to get your belongings soaking wet.

by: Matt06/04/2016

Easy to install and great fit. My only complaint was there was extra screws included. I had to watch install video to see if I had missed a step. Come to find out there was just extra screws.

by: John 05/22/2024

Just got it installed. The installation was easy and straight forward. Sits flush to the bed and looks great.

by: Ben05/12/2022 One Year Later

The Bak Flip F-1 has proven to be an excellent cover for my 2020 GMC 2500HD. It was easy to install with a friends help. It is a good looking cover and has been waterproof. It is very secure with the gate locked. Very pleased.

by: Ian02/26/2025 One Year Later

Great product...Has worked well ...High Quality - Thank You BLW

by: Richard12/02/2023 One Year Later

It would be a great cover if it didn’t leak. I have to be very mindful of what I put in the bed so it doesn’t get damaged by water.

by: Ned08/08/2015

This is one of those components you get what you pay for and I couldn’t be happier. Fits perfect, looks every bit as great as shown in all the pictures. My brand of 5th wheel hitch fits below it.
*** 1 Issue - The installation instructions have room for improvement, having poor illustrations and reads difficult. The installation of this product is extremely easy but the instructions make it sound difficult.

by: Peter12/27/2023 One Year Later

I found the Back Flip cover a well-engineered cover. The cover works very well and with a some adjustment it can be waterproof.
The only issues I have had are the back flip knobs fall off and I have to replace one. The other is the interior panels dent very easily from cargo hitting it. I was planning on putting thin diamond plate panels to help prevent anymore damage.

by: Richard 08/15/2023 One Year Later

Love it. Just wish there was a tie down for when you just have 2 folds open.

by: David 06/27/2024 One Year Later

Works great at protecting cargo. Am still able

My entire experience with etrailer.com was excellent. I spent numerous hours researching the hitch and tonneau cover set up I wanted for my 2014 Ford F250. The majority of my time was on the etrailer.com website reviewing Q&A, installation guidance and videos, and expert advise. I chose the Reese Elite Series 5th wheel hitch and the BakFlip F1 tonneau cover. Both products arrived within 10 business days. Installation was as easy and straightforward as expected. The BakFlip F1 really dresses up my F250 and the BakFlip technology makes it very easy to use and gives me full access to my truck bed as needed. The Reese hitch has performed flawlessly.

Can BAKFlip F1 Tonneau Fold Up And Allow Fifth Wheel Hitch Access 2025 Chevy Silverado 3500HD
Hey Raymond, with the BAKFlip F1 part # BAK37FR folded up but not up against the back of the rear glass of the truck you will be able to tow your fifth wheel trailer. There would be enough access to the truck bed and hitch since you have a long bed and this is a quad fold and not a tri.

Can BAKFlip F1 Be Partially Open While Operating 2025 GMC 3500 Long Bed
Hey Scott! It is not possible to use your vehicle with the BAKFlip F1 # BAK37FR partially open like that. The only acceptable positions while operating the vehicle are folded up (all the way to the header) and flipped up. See the attached photo. Is there a specific reason you want to leave it half way open? A better choice for that would be a retractable cover like the Pace Edwards JackRabbit # PE54UV. This can be locked out at any point along the rails.

How Far Does The BAKFlip F1 Quad Fold Cover Stick Out Into the Bed When Folded
The BAKFlip F1 Hard Tonneau Cover # BAK37FR will stick out into the bed approximately 23" when folded to just the first of the four panels. I wasn't able to get an exact dimension for the thickness but was told the panels are about 3/4" thick so you'd be looking at the stick stick up roughly 2-1/4" from the top of the bedrails.

Roof Rack Recommendation with Longer Crossbars for 2020 Chevy Silverado 3500 Long Bed
Yakima has roof racks that do fit your 2020 Chevy Silverado 3500 Crew Cab like the HD bar rack part numbers # Y01157, # Y28TR, # Y03541, # Y27FR, and # Y06124 which gives you a 60 inch bar setup with plenty of weight capacity. This would be best way to carry the accessories you have now as the ladder racks have wider bars than what standard roof rack accessories can fit. Then for a fold up tonneau cover the BAKFlip F1 part # BAK37FR would be a really great option as well that is confirmed...
