I don't know what other pickups are like but Ford didn't do anyone any favors with all the curves in the tailgate. Have said that I followed the directions exactly and got a good seal except for the bottom corners. So I took the little bit of extra and put a piece in each corner (picture) and that pretty much took care of the gap. I have a 2019 F-150.

Got it installed on my 2019 Chev. Silverado and everyone wants to know where I got the light bar ! Good 2 face tape application and nice and bright too. Fast delivery and they answered all of my concerns. Nice doing business with a company that appreciates customers.

The product arrived on time and in good shape. I cleaned the area where the item was to be applied per the instructions. After one week the item started to pull away from the bed of the truck and dirt got onto the rubber sealing area and would not stick onto the truck. I don't know if I did something wrong or the adhesive on the rubber was defective, which sometimes happens during the manufacturing process. In either case, I will be looking for another tailgate sealing solution and that is the reason I only gave three stars for the product review.

product failed to hold on truck. i used another product 12 X 12 square which has held in place with no problems.

by: LaVern H. 10/22/2017

The Extang MaxSeal Tailgate Seal is a great product.It is soft,durable & flexible.It keeps it's shape & does not flatten. I like that it keeps water & dust out of my truck box. I recommend this product to anyone who has a cover on their truck box.

Its still soft & pliable & is keeping the dust &water out of my truck box. I love it !!!

by: James 03/28/2023 One Year Later

The seal works very well on my 2018 Silverado, with the exception of the area near the top of the tailgate, where there is just not a good way to seal it. Not the fault of Extang tape, so I sealed almost all the way to the top and I never have any issues with dirt or rain getting in. I would buy this product again.

This product has stayed in place just perfectly for the past year, much to the chagrin of my naysayer friends who didnt think it would work. It has held its shape and kept so much dirt and rain out of my truck bed. Very happy!

by: Garret 07/08/2023 One Year Later

The product is doing a reasonable job of keeping dust out of the covered bed interior but is starting to loosen and correspondingly allowing more dust into the bed due to the adhesive starting to fail. I will reset the seal with some automotive trim adhesive.

I removed the seal from the truck, reattached it with 3M weatherstrip adhesive and remains in place doing what it was designed to do.

by: CT 06/29/2017

The MaxSeal Tailgate seal was very easy to apply when following the instructions. The product is well made and works great for keeping dust and moisture from entering in around the tailgate. Without the seal with the topper shell installed the dust and moister was entering the bed of the truck. Now it is not.

This is not my first purchase from etrailer and I will continue to purchase from them. The customer service and fast shipping is tops in my book. They have always been very nice to deal with and their products are just as they describe. Thank you etrailer

It leaks after about 6 months. New truck so it was installed on clean surface. It had has leak in center around wires going into tailgate. After attempting to fix the seal no longer sticks. Entire cargo load was covered with dust after a trip to colorado and back.

by: Paris 05/20/2020 One Year Later

Product adheres to the surface and greatly helps prevent spray from the tail gate from entering the truck bed.

A clean surface is very important. Product adheres nicely. I Have a F-350, 2018. Hence, it takes more work to get an almost perfect dust tight seal. After one year, it functions as good today as it did immediately after installation. I do definitely recommend this product.

by: William 10/07/2019

Following directions, particularly cleaning surface with alcohol wipe, rubber gasket application worked as promised. The Ford F-150 has some unusual curves on tail gate, yet as instructed, the gasket looks to seal as promised. I use a Backflip cover so sealing tail gate was needed some for better dust and water removal if they try to enter while in motion. Time will tale on durability of product seal and adhesion to truck tailgate area. Looks very promising.

by: A. L. 10/18/2016

Good flexible rubber material, strong self adhesive, sealed the bottom of the tailgate tightly. However, the bead size is too small to seal the sides of the tailgate on 2016 Chevrolet Silverado. The gap between the tailgate and the bed on the sides of the tailgate is wider than on bottom of the tailgate. In addition, the tailgate shape is curved or convex on the sides, which contributed to the wider gap on the sides of the tailgate. Therefore, I rate this gasket 4 out of five stars because it does not provide a complete seal on the sides of the tailgate.

by: David 05/24/2022 One Year Later

The kit is easy to install and it stays installed.

I have a Honda Ridgeline with a Leer Topper. This kit sealed the tailgate very well and reduced the inflow of dust from gravel roads in the back by like 80 percent. The problem is that the corners of the Leer Topper hatch does not mesh well with the tailgate of the truck. There is two large holes in the corners where the Leer Topper meets the tailgate. To keep more dust out you need to stuff rags in these holes.

by: David 09/14/2021 One Year Later

Bought this seal for a 2020 Silverado. It keeps the majority of the dust out, but I had to add some of my own material to fill the gaps on either side of the tailgate. This particular seal is not wide enough and the need to fit small pieces makes it look cheap.

by: George 06/01/2019

The 3m tape could have been wider. I wound up adding 1 inch wide 3m tape over the tape it came with. The extra width gave it more holding power, and the extra thickness of the 2nd layer made it fit better around the spray-in bed liner. The seal itself is well made. And the shape works well to seal out the rain. I covered it with a gap cover to prevent things from falling in the gap between the tailgate and the bed.

by: Randy A 10/23/2019 One Year Later

Added this with a tonneau cover. Easy to install. Found it good to install and leave tailgate closed for a couple days for the foam to memorize the tailgate for a better seal.

by: Mike G 04/22/2020 One Year Later

This is great for sealing up the small air gaps between the tailgate and the bed. Much reduced dust inside the bed area. (I have a bed cover also.) Great product, would purchase again.

by: Hbw 04/05/2020 One Year Later

This product lives up to its promise: both functions and installs easily. The bonus is you receive etrailer excellent customer support and service. Thank you all at etrailer, pleasure doing business with your company.

by: Gary 04/15/2022

Just got this gasket material to seal my tailgate on my 2022 Ram 2500. haven't had a chance to install it yet but the material quality and adhesive looks to be a great quality and will hold up well to keep dust intrusion to an absolute minimum for sure. Stay tuned.

by: Keith 10/26/2020 One Year Later

It seems to work pretty good. I still get dust coming in between the tailgate and cap that is on the truck but it helped.

by: Fbrad 05/30/2019 One Year Later

The product is holding up well. The issue from the beginning was with the size of the gaps in the tailgate itself. Ford has not made any considerations for a vehicle that drives on dirt roads. Very poor engineering!!

by: Brandon N. 04/03/2017

Seals the tailgate well on '15 Chevy 2500HD. Install tip: If installing with a Bedrug or Bedtred or spray in liner flip it upside down along the bottom of the tailgate.

by: Don 10/19/2018 One Year Later

The seal across the bottom of the tailgate won’t stay on it is too thick and the tailgate pushes it down when closed. Was a waste of money

by: Joseph 03/08/2018

This is a great seal for the gap around the tail gate of your truck, also works great for door weather striping. Have used it many times and always works great

by: Brandon M 10/18/2020 One Year Later

It’s ok for what it does. There’s no way to truly seal it off and still have a functional tailgate.

by: Joel 02/18/2018 One Year Later

I've had this product on my tailgate a year now. It has performed very well.

Troubleshooting Extang Trifecta Soft Tonneau Cover That Flops In the Wind
I reached out to my contact at Extang and was told that air may be getting underneath the Extang Trifecta 2.0 Soft Tonneau Cover # EX92830. To fix this issue, drop the tailgate and look inside the bed to see if you can see light coming through in the front. If you see exposed light, Extang recommends using weather seal to seal off areas where light is exposed. With everything sealed up properly you should not have further issues.

Tailgate Seal for 2025 Ford Ranger Lariat
Hey Phil! To fill the gaps on your 2025 Ford Ranger Lariat's tailgate, you will want to use the Extang MaxSeal Tailgate Seal # EX1140.

Recommendations to Seal Up Leaking Tonneau Cover
Typically when water starts to seep into a truck bed with a tonneau cover installed it's coming in from the cab side or through tiny openings at the tailgate.

This is a nice adhesive-backed rubber weather strip that's going to keep out rain, snow, and dust from sneaking into the bed through the tailgate and bed side walls. Then...

Troubleshooting RetraxONE MX Cover Leaking at Tailgate on a 2016 Ford F-150 with 5-1/2 Bed
I reached out to my contact at Retrax who said that the number you gave me means that you have the RetraxONE MX Hard Tonneau Cover # RT60373 on your 2016 Ford F-150 with the 5-1/2' bed. If your cover is leaking at the tailgate and you have already tried replacing some of the seals then my contact at Retrax said it sounds like the rubber seal that is connected to the cover itself is in bad shape. Unfortunately that is not available as a separate part so the only way to change that out is...

Best Tailgate Seal For Truck Bed
Tailgate seals are universal fits, so there isn't one specifically made for a 2022 Ram 1500, but having said that, the best overall tailgate seal is from Extang: - Extang MaxSeal Tailgate Seal # EX1140 I like the Extang # EX1140 the most due to it's width of 1-3/8 inches, which is more than any other seal to help fill in the gaps better than other seals.

Can Extang Tailgate Seal and BedRug Be Installed at Same Time

Tailgate Seal for Extang Tonneau Cover on a 2014 Chevrolet Silverado 1500
The tailgate seal you need for your 2014 Chevrolet Silverado 1500 is the Extang MaxSeal Tailgate Seal part # EX1140 which is cut to fit.

In order to install the tailgate seal all you will need to do is measure the length of the seal you need, cut it, peel off the adhesive backing, and stick it into place.

Tailgate Seal For a 2018 Ram 1500 4X4
