DIY 2008 Rear Inner Fender Liners
DIY 2008 Rear Inner Fender Liners
I recently purchased a 2008 Super Crew Limited. Nice truck and I am happy with it. However, there are a few things that bother me and I have set out to correct them. One was the absence of rear fender liners. It was hard to believe Ford did not include them. After all, my 1989 has them. They keep all the slop from flying back into the rear bumper. After searching this forum and the web, I decided to make my own since I really didn’t find anything useful. Others suggested using the liners from a F350 Super Duty, but I haven’t found anyone who actually did this.
I live near a truck stop, so I purchased one 24” x 36” x 1/8” plastic mud flap used for 18 wheelers. It is a nice matte black and has a textured finish. The cost was $20. I used thin cardboard to create my pattern. This took some time cutting and fitting, but it was much easier than cutting up my plastic mud flap. Once done, I transferred the pattern to the plastic flap and used a jig saw to cut it out and a file to smooth the edges.
I mounted the liner behind the rear fender support bracket and used the top screw from the bracket to help hold it in place. The fit is tight, and so far, I have not had a need for any further anchors. If down the road I feel the need, I can use a few push plugs to anchor the liner to the inner fender.
I hope my pictures inspire others. Next on the agenda it to engineer some sort of cover to keep slop from flying through the front bumper gap. Any suggestions?

Great idea and write up.
Love white but I'll tell you, even with my red truck, I had to paint inside the rear fender wells black. It bugged me to see that red, let alone white ..... inside the rear fenders.
Push plugs is what I always called them, first time I ever saw them called "Xmas tree plugs". I had to read it a couple times before it dawned on me what you were talking about.

Thanks. I made the edit to call them push plugs. I called them xmas tree pugs because the plug part looks like a xmas tree. 
And yes, I plan to paint/undercoat the inner fenders once the whether gets warm. I agree, all that white is hard to keep clean.

That is a good idea, I didn't think about chopping up a full sized mud flap for it. I will have to do that.

Funny to see this. my dad just bought OEM one's for his 04 Cummins. I was saying a few weeks ago how bad I wish they made them for my truck. It's a whole piece that goes into the fender. I'm going to have to do some experimenting I think. Fantastic job man
So a 2004 F150 has inner fender liners? Didn't know that. May have to check into that. Thanks
Tasca Ford parts only shows to have them for a flareside bed.
