It appears all the cross seams leak.

The cover arrived in great shape and the installation instructions were clear and easy to follow. I would definitely purchase again. The special shims that were needed for my '26 Silverado 2500HD didn't follow the prescribed size recommendation and I had to deconstruct and remove both side rails to take off some of the shims, but then it worked beautifully. All's well that ends well!

Love it simple install and works flawlessly!!!

Great product

Yes, you can make it fit. There are no instructions for my 2025 Tacoma and there are no videos for that year Tacoma.
The instructions came with Ford, Chevy and Dodge specs. But not Toyota.
Can it be installed by an amateur?
No.
Can it be installed by someone with a little mechanical ability?
Yes, with some screwing around.
It's a pretty good tonneau cover but the topper is ugly and not expected to be completely water tight. OK, fine. It is workable and the price is good.
I'm going to use it.

The box was missing all hardware only the rails and cover were in box. Been waiting for it to show, they said 5-7 business times. No rush shipping offered.

I installed this cover on my 2010 Toyota Tundra Platinum many years ago and my Chevrolet Silverado High Country a few weeks ago and recommend to all truck owners. It greatly improves usefulness of the truck bed without sacrificing the ability to haul large items when needed. Also improves gas mileage as well. Great product.

I bought the tonneau and soft topper for my 2024 F350 8Ft. Truck. It fit perfectly and is a well engineered product. Good quality. I would recommend buying this product just a little tricky installing it for the first time.

Great experience from start to finish. Shipping is fast, customer service is excellent, and videos are informative. Highly recommend this site!

Fast shipping, great fit for the truck, thx

Received in excellent condition. Everything fit like it was designed to. Easy installation. Took about 1 1/2 hours to install by myself. Was missing one thing. Half round rubbers to protect cab when fully open. Very pleased.

Great

BAKFlip MX4 Tonneau Cover - BAK448446

Installation was easy enough, but the overall fit is a bit disappointing when compared to the cover I have on my Dodge Ram. The corners are not tight apparently due to the stitching of the fabric and will likely allow rainwater into the well bid

Long wait but worth it. Expensive but it is top notch!

This is the third tonneau cover I have installed from access. I would highly recommend them to anyone. They are a quality product and they have lasted every time I put them on.

Excellent customer service, HQ took care of an issue with my order fast and was able to get my new product in just a few days. The BAK X4s is very well designed and durable, Highly recommend

After three weeks of research, i decided on a Bakflip from Tonneau HQ. Great price and extremely fast shipping. Cover was delivered with zero issues and installed perfectly. Thank you!

After reviewing many tonneau covers and price shipping every dealer, I stumbled upon Tonneau Cover HQ by accident. They had the best price, fastest free shipping, and great customer service. I received the Bakflip cover shipped today and installed it in under two hours. Great experience.

Easy installation.great quality. Worth the money

This cover at first seemed great but at the 2 year mark I'm looking for a new one! The cover itself is built very well but the release bars that are used pretty much every single day are cheap plastic and broke about 6 months ago. The gaskets on every panel have also cracked and leak. Their customer service is very good at Bakflip and they have sent me parts that have fallen off but I believe for the price this unit should last more than 2 years! It may work for someone who doesn't use it on a daily basis.

I really enjoy my new bakflip mx4 bed cover. Had a couple of screws missing and a damaged rail. Customer support team were fantastic and professional. They sent me a new set of screws and rail to replace the missing/damage part immediately. I highly recommend this product. Thanks

I have a 2019 Ram 2500 and the cover fits well. The only issue is that the rail ends are sharp and would cut into the tailgate protector. I filed them down and covered them with PVC tape. Another issue I found is that the cover does not seem to be very secure. It's the same with most of the covers in this price range. I added some brackets to the inside of the cover and I use chains to hold it down from the inside when I am carrying expensive loads inside. It gives me peace of mind knowing it will be much more difficult to break open.

Fast delivery. Great customer service. So far so good. This is a two person installation with good instructions.
