Kydex wheel well liner.
This project might take a bit of explaining. Bare with me and let me know what you think.
There might not be a real need for this, but the idea kept kicking around for long enough, that things moved to the next level, who knows how far it will go, but here I am for now. In this case, the issue starts with the right front wheel well. There is an A/C line that is somewhat exposed. Lots of mud and rocks gets kicked up off the tire and packed in around the lines, into the frame body mount, the underside of the body and the outriggers to the sliders. I like to get my truck clean after it gets dirty, so I've been pretty thorough about spraying all that debris out when I wash the truck. As you probably know, its not the easiest place to get clean and its easy for mud and rocks to hang out there and all along the underside of the body outside of the frame(even worse with all the AHC stuff in there). I had a friend mention that the rock trapped around his A/c lines caused a leak and he had to replace the line(not sure how common that is, but I can see it being an issue). After seeing how the rocks from my tires can really beat on the undercarriage parts, I decided that it would be nice to have some added protection for the A/c lines and to help keep some of the mud and debris out of that area.
I have some previous experience from my FJ40 making some fender liners out of Kydex to accommodate the tube fenders that I built. Here is a quick example of that.
I had some remaining .090 Kydex sheet so I used that for this project. I made a rough template and transferred it to the material and got started with a few priorities in mind.
I wanted to use existing mounts on the body- no modification of the body or frame(no cutting or drilling holes).
I wanted to leave the stock fender liner and body trim complete and in place- that way, if this didn't work right(look or sound right) then it could be removed and I'd be back where I started(-time, +learning something).
I realized that I'd need some additional mounts, so I'd make them with Dzus fasteners at the sliders with some room for the material to flex between the body and the sliders(ie frame). These mounts would be out of the way and allow easy removal.
No mud flaps here, they would probably just get in the way.
Then I made an extension stud to help mount the liner using existing bolt hole in the body.
