School me on fender flares

Hi guys, contemplating getting some aftermarket fender flares for my 18 JK. I haven't decided on the specific flares yet but I prefer the flat short ones. That part I am not confused about though; what I am confused about is this whole fender liner thing.

I understand when I remove stock fenders, I will have to also remove the stock fender liner - which leaves the internals around the tires all exposed to the elements correct?

So installing the aftermarket fenders means that the internals will be all exposed to the elements correct and in general not look very clean/sophisticated? So, I'd like to have that part covered/hidden as OEM as possible.

What are my options to make that happen? Browsing online I am coming across items labeled 'fender liners' but they appear to be heavy metal material and not rubber/bendy. Is that a thing too?

Basically yea please tell me whatever I need to know to undertake this venture. Oh and I am trying to be big on DIY's with my Jeep so likely will only do it if it's DIY'able. Instructional videos will help.

Thanks very much in advance.

You definitely want to run fender liners. Aside from keeping gunk out of the engine bay, there is a large wiring harness on passenger side you need to protect- it is directly in line where a tire could catch it, and if that harness goes, your Jeep is DOA waiting on a tow truck.

Yes the aftermarket are aluminum or steel or whatever metal. More durable than plastic.

With some fenders you may be able to just trim the factory plastic liners and reuse. Would all depend.

3M 3584 rubberized undercoating is what I did on the rear. It’s quite a big undertaking because I had to mask off all the areas on the body, took some time to finish that job up.

I have Poison Spyder steel flares.

In front, I trimmed my OEM liners.

in the rear I just sprayed some wheel well rubber coating, no liner.

I'd like to get high clearance fenders to clear my 35's but I think I have an impossible set of criteria . (1) I don't want to drill and rivnut (too permanent) (2) Want them as wide as factory flares so I dont throw rocks and mud (3) don't want steel - too heavy and (3) Dont' want to spend $2,000 for a full set with liners...

I think I may end up going the route of trimming the factory flares and making "fake" tube fenders with bent & painted PVC pipe...

Thanks for the comments so far. Although I still not quite clear as to what I need exactly and what the install would entail.

Does any fender liner work with an aftermarket fender flare? Or are they brand/model specific? I saw some fender flares that I liked the look of for under $200 on eBay but I am not sure what sort of liner I can have with them or if I'd be able to modify my stock fender liners. I am not a very good DIY person so I doubt it....

The install really goes by what fender flare you go with. like the PS ones have a couple of brackets per fender that bolt in before you put the fender so they can take a hard hit. The Bushwacker fenders have plastic pieces then you slide the fender over the plastic pieces then bolt down to them.



Like with anything you get what you pay for. the eBay fenders usually require more trimming or finessing to fit correctly. Usually most aftermarket fender liners will work with any fender, you may just have to play with the fitment of that liner as well.

Wow this options seems good. The price is aggressive too and I like the look. Are you saying that I can use the stock liners for both front and back with this kit as is without any trimming etc? Any videos of install showing how the fender liners work with these flares?

If so, what's the best way to order these - straight through your website or messaging you on here for the 'forum deal'? I am located in Canada if that matters. Thanks.

Well I guess it doesn't matter about that specific flare as I can't acquire then in Canada anyway. So I am still on the hunt for something that looks like that which I can either make work with stock liners or even an aftermarket liner that I should look at. Thanks for the suggestions in advance.

just use a mailing service with an american address. im in BC and i have ordered many parts recently using this system. I used summit warehouse in Orville WA, price vary s depending on the cost and weight of the goods.

Cheers.

Heres's a video that shows how to use the stock liner which is what I would do in that situation.

Well, you can simply trim the factory front liners to fit. And either trim the rear plastic liners or just paint the wheel well. Or you could go with cheap and getting the matching SmittyBilt liners. Or buy nicer ones, like PS, JCR, or just about any other.

I think I’d like to go with a proper set of liners instead of trimming the factory ones. Can you recommend something that isn’t too hard to install, doesn’t require drilling etc and any special riveting tools like I am seeing on a lot of these?

I've searched high and dry for an installation video for the Smittybilt XRC Fender Liners. I figured might as well stick to the same ones and the price is decent. But I can't even find a single installation video on them especially for rear. The RockCountry ones are my second option but not really cause the rear require cutting which I am not comfortable with. Drilling too I've never done before but doesn't look there's another option as all of them require drilling. If someone can find me a video on xrc liners for front and back that would be great.

They are just fender liners, you should not need a video on installation. Just read the instructions. The fronts require drilling a pair of holes in addition to using the two stock mount locations. The rears require drilling something like five holes. No cutting should be required.
