The shape of rubber is ideal to keep the dust and dirt out...and the glue on the seal has held tight...good product. 628660

Very good product. I have a GMC Sierra and there is a bigger gap at the top sides, but there was enough material to double up at those spots. No water or dust leaks, love it. 698975

It works great. The key is careful plac ement. 672866

by:

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. 651444

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. 650786



- EX1140
by:

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. 308385



- EX1140
by:

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 575785



- EX1140
by:

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. 651584

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

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!! 649182



- EX1140
by:

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. 661655

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. 784113

Ask the Experts about this Extang Tailgate

  • Can Extang Tailgate Seal and BedRug Be Installed at Same Time
    Bedrugs like the part # BRQ99LBK go over the hinge of the tailgate and truck bed. A tailgate seal like the part # EX1140 would not interfere with this at all. They would work well together.

  • 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...

  • 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. What you can do to try and prevent this with your cover like the Extang eMAX # EX72780 is use the Extang MaxSeal # EX1140 to create a tight seal 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....

    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.

  • Recommended Electric Dump Valves for 2014 Sanibel 3600 5th Wheel Trailer
    For the electric valves, we only have the 3 inch options. We have the hub to hub # E40B-8, the hub to spigot # E40-8, or the spigot to spigot # E40A-8. If you were to convert your 1-1/2 inch to a 3 inch, we do have the double 3 inch electric valves with 3 inch hubs # E85-8 or 3 inch hubs to lug fitting # E84-8.

  • 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. The Extang Replacement Side Seal part # EX32560368 would not work well as a tailgate seal so I cannot recommend this.
