ESI ROK Block 4.25 inch Tailgate Gap Cover and Ultimate Tailgate Seal with Taper Seal 5 1/2 feet for Sidewalls

This stuff works as advertised, the dust in my bed is virtually nonexistent now. Installation was easy, and the tape sticks like crazy, so lay it down right the first time, because it's not coming off!

This kit does it all. Instructions are clear and easy to follow. Covered the tailgate gap in my 2016 F150 Lariat with no problem. Adhered to my spray in bed liner with no problem (follow instructions to the letter) and is holding well. Kit has enough ROK BLOCK and side gasket for a standard pick up bed/tailgate with a little left over. Tip: Let adhesive dry/cure for 24 hours with tailgate open and place a thin, heavy object on tailgate seam(small diameter pipe or re-bar) to "mold the seam to bend correctly( into the gap) rather than pucker into bed area like some reviewers have said. This should keep mud/dust out of covered bed area.

Purchased for 2024 Jeep gladiator. The tailgate gap filler is great. Easy to install and has stayed in place. The weather stripping for the side of the tailgate has been good. I wish the adhesive from the gap filler was on the weather stripping. The smaller pieces at the top of tailgate are not staying in place. I think the better adhesive would help.

I love my Ram truck but the gravel dust was ridiculous! Followed the directions and easy install. It works great and no gravel dust!

This is awesome! No more digging junk out from the tailgate gap! Install was really easy and the adhesive is super strong. I've bashed it with all kinds stuff and drug things over it and it hasn't budged. I've recommended it to all my friends with pickups!Update on 9/24/18: Unfortunately I did a stupid thing and backed a trailer with my tailgate down. Now I know how tailgates get that giant crush-dent on the top of them. I always thought people dropped heavy things on them, but nope, backed a trailer with the gate down. Anyway, I had to replace my tailgate because I just couldn't stand it. Removing the Rok Block added an extra hour and half to the process! I couldn't believe how well it had stuck! It took a lot of strength to remove the gap cover and it left residue on my bed which I had to scrape and pick at for over an hour to get off. I was worried about it because I had recently transported my chainsaw and gas can and the can had fallen over en route. There was gas in the back of my pickup just sitting there soaking for at least an hour. I thought sure it would have harmed the adhesive on the Rok Block but nope - it didn't bother it at all. I was really amazed at how well. I ordered a new set for my new tailgate and am 100% confident it's going to stay in place for a really, really long time in spite of the abuse things take in the back of a pickup!

Received as described. Works well

Does a pretty fair job of keeping the dust out. It does not fill the lower corners well enough.2025 f150 XLT

Followed instructions to a tee, and it took me a total of 15 mins. Of course I pressure washed the area first and allowed to dry for 24 hours. Bummed the heat up in garage to 65 for 24 hours too. Seems like it’s stuck to the spray in liner well. Tailgate alittle tougher to close but closes fine. Recommended for sure to keep rain and dust out.

Solved problem in my 2018 F-150 with dust seeping into box through crack between bottom of tailgate and box. Also sealed gap between sides of tailgate and box. It has held up through this harsh, cold winter. Especially great for keeping water out when going through high pressure touchless commercial car wash. Box has 3-fold hard BAK tonneau cover.

This works better than expected

I am always hauling dirt or gravel and I finally got fed up trying to clean out my box so I bought this kit. The activator pen that you apply before you stick it down is very good. Make sure you have it right where you want because once its down its forever . I decided to use velcro on the tailgate itself with also using the activator pen because I do take my tailgate off the odd time based on weird loads I haul once in a while. I have noticed that when I first laid this down that I made sure that the tailgate seal was folding inwards as I lifted the tailgate. Now that I have done this a few times it just naturally folds inward which I think will help extend its life. Much easier to keep my box clean and less time consuming

Quick delivery, working excellent on my Tacoma

This is a great product. Works well to keep twigs and leaves out of the gap between box and tailgate and is an excellent tailgate seal
