2021 JLU Rubicon 392
Hello everyone. I have read (can’t remember if here or on the general JL forum) that the factory wheel well liners are a weak point on the 392 and with extended driving time (over 2 or 3 consecutive hours) that these basically start to cave. True or not?

Either way. If I’m shopping for an upgraded/aftermarket version…can somebody recommend a set that looks as close to factory as possible with enhanced durability? At least sleek and black so they basically disappear in the wheel well. Not a fan of the aluminum versions with all kinds of cutouts and branding and vents in them.

Thanks all!
 
Mine got destroyed on the way home from the dealership , 500 miles. High winds and highway speed and they contact the tire and get destroyed. I molded new pieces in the damaged area and zip tied the rest of the edges to the frame to stop any further damage. At some point I will replace with stock new ones. But I didn’t feel like pulling a part a new Jeep when I got it home.

I noticed the inner liner on the driver side seemed more flimsy than the inner liner on the passenger side. The only difference between the two sides was the amount of heat shield glued to the inside of the liners. The more heat shield coverage, the stiffer the liner. Adding heat shield might be a solution.

It was my passenger side…. I think it depends on wind direction. I did however add heat shield to the plastic pieces I added.

The only reason I was even looking at the inner fenders is because I was trying to find the source of the intermittent “clicking” sounds I hear when I get above 70. I assume it is wind related but I haven’t found the source. In the process I did end up trimming some off the bottom of the inner fender on the driver’s side where it was catching on the top of the suspension. Unfortunately that did not eliminate the sounds.

So far, so good with no issues, but I have also read the posts and am concerned for WW Liners in the months ahead. That said I have gone on a few 6 hour drives at highway speed (75ish) and no problems yet. (At about 4K miles now)
 
I have American Adventure Lab inners. Very small logo that I color matched. I ordered satin black and got all the hardware black. Looks pretty clean. I did a full fender chop and used their high line fender brackets and lights. You have to get the diesel version of inner fenders if they aren’t specific to the 392.

Looks very sharp and clean. Thanks for sharing 👌🏻
I have gone offroading with them three times in close to 100 degree temperatures. No problems with them.
interesting. Thanks for sharing

I really thought I was going to do the AAL liners. I just need the plastic/rubber outer lip because of gravel roads. i wasn’t sure you can keep those and the AALs.
 
You can keep the outer trim, just install it by only removing the top most piece of the inner fender support or just leave it if you don't need the fender clearance - it will gather road dirt though. If you use highline fender lights like Quake you will need to do some creative trimming on the front of the inner fender support piece.

These are plastic inner liners from Paramount Industries, they are half liners that stop at the body line when you remove the stock liners.

Do these improve clearance at all or are they pretty comparable to stock? Also, are those rub marks in yours? Any issues at all?
 
They are to replace the stock liners when you remove them for more clearance, they only go to the body line not to the edge of the fenders. The rub marks are from not taking the tires off for installation (sliding them over the tires to get them in place for installation, to lazy to remove the tires) :rolleyes:

They look good! Definitely an option for me. Do they feel stiffer/more durable than the factory ones?
 
They are 2 to 3 times thicker than stock, front will not fit a 392 on the drivers side due to the windshield wiper bottle but I am supposed to take mine down to them for a fitting.

Ahhh thanks for the heads up
