not at all, to me it fit great. the smaller 4 inch one wouldn't work. but I did put it on a little tight I think I could have installed it so that the pre bend in the product was already slightly bending down. it wanted to fold upwards and down in other spots forcing it to bind. but with the bed mat on top of it, it forces it to bend down when the tailgate goes up. If you look at their site it fits exactly the way they show. If the factory spray in liner covered more of the tailgate I wouldn't have done it but there was too much bare paint showing. my 2018 was all scratched up I wanted to prevent that this time. plus because I have the bed mat I actually cut the Rok Blok around the two bolts in the bed so it fits flat and not up and over the two bolts.
they have a kit that has both the tailgate seal and the rok block. I didnt buy that. I bought them seperate because the 10 ft tailgate seal gives me extra for down the road and it comes with a 14 inch piece of the extra thick tailgate seal. I was able to use that at the wider spots and use it differently than they showed. less needed and worked well.
