Big mud flaps on a JLUR.

[wibornz]

I am thinking of making some for my JLUR for when we go to Alaska. We tow a camper and I am looking to not destroy the camper from mud and rocks being kicked up on to the camper.

Pics of camper that are towed in Alaska. I suspect that I will do a couple thousand miles of dirt roads.

Note, the above vehicles all have their tires inside of the fenders. Mine are not like that. I have a -3.5 off set wheel and get a lot of tire poke.

I have metal inner fender liners. I am thinking about buying bulk mud flap type material and rivet nuting

the mud flaps to the Jeep inner fender liner creating a mud flap that I can easily put on and take off. I would only be using them at slower speeds on the long dirt road sections in Alaska and Canada. I am thinking that the mud flap would go from the top of the middle of the fender to a couple inches off the ground. So with 37s on it will be a long mud flap.

For a reference, there is 414 miles of dirt road to Dead Horse Alaska. For a total of 828 miles plus to include any off shoots and so on.

Then, (94 miles) up to Tuktoyaktuk (Tuk for short), connecting the rest of Canada to the Arctic Ocean. So another 200 or so miles up and back to Tuk in Canada. Making for 2000+ miles of dirt road travel.

Any advice or insight to my plan? I can also if needed drill into the stock plastic fenders as I have two sets of stock Rubicon fenders at home that I can put on when I get home.

What's the purpose of your tires sticking out 2 inches from the fenders?
You don't need mudflaps you need to eliminate your "poke".

This is what I did. I can quickly remove when I’m not going off-road/gravel road. Obviously you would need them bigger but if you bought thicker( 1/4” maybe) they would be rigid enough to hold their shape. These are 1/8 thick. Off Amazon. Not as pretty and polished as most would like I guess but my Jeep is more of a tool then anything else.

When I used to drive in Utah all the time all of the lifted trucks and jeeps had these giant mud flap kits on them maybe you should look into that and see what they're doing they look like they work pretty good.

We have the stock wheels and 35's still without after market flaps and are surprised at how much abuse our trailer has taken from rocks and mud/dirt off road.

I have a love hate relationship with rivnuts and no experience driving in Alaska; though like your removable mudflap idea—

It's pretty easy to add the "Extreme Recon" fender flare extensions.

That wouldn't eliminate the need for big flaps, but could provide a useful supplement.

And unlike the flaps themselves, so far I haven't encountered any need to remove the flare extensions for wheeling.

I have a set of XL RokBlokz sitting in my shed that I've been meaning to install for winter. This thread is a good reminder for me to dig those out.

EDIT - On my Tacoma, I built some oversized flaps by laminating up some layers of ABS plastic from TAP Plastics. They were three layers thick at the top for stiffness, Two layers thick in the middle, and a single layer thick at the bottom for flexibility.

This is the stuff. I *think* I used 3/32" thickness? (Might have been 1/16") I had them cut the custom sizes I needed with rounded corners, then laminated 'em together with ABS cement.

XL Rokblokz. Easily removable with thumb screws. The rear ones are adjustable in terms of how far out they poke. I have them on the JLURXR. Not quite as much poke as you have, but I am pretty sure I could extend them several more inches. In can investigate further later today.

Check out Rock Tamers attaches to you hitch.

Ah, here's the photo of when I first made them. The original version was probably five plies of 1/16" Then a few years later when I made a new version, I simplified to three plies of 3/32"

But you can see - they're stiff enough to be held in place with only about a 3/4" overlap of the mounting surface. Ordinary "mud flap" material can be flexible enough that it blows up out of the way, rendering it mostly useless, at higher speeds.

As others have said, XL RokBlokz. They're expensive but worth every penny and will adjust enough for your tires.

Also, it's a fun drive, enjoy yourself. Make sure you fill up frequently between Haines and Tok. There's not as much distance between stations anymore, but there can be serious delays that will suck up the fuel.

If you're into Antique cars, there is the Fountainhead Antique Auto museum in Fairbanks : https://maps.app.goo.gl/H1KCJQyCTxvt85RY6. If you have time, Denali is like 3 hours SW of Fairbanks and well worth the detour. Lots of good beer up there: 49th state brewing in Healy if you head to Denali. Silver Gulch in Fox, north of Fairbanks. HooDoo in Fairbanks. I usually fly to Deadhorse, so hopefully someone else who has driven there more than once can give advice.

(E) For my RokBlokz I didn't like how long the factory thumb screws were, so I ordered some 10mm long ones from Amazon: https://www.amazon.com/uxcell-Thread-Knurled-Clamping-Knobs/dp/B07KPG5L33?th=1

The knobs are m6x1.0 pitch if you want to find your own.

You don't need mudflaps you need to eliminate your "poke".

Not sure about yours, but before I installed mud flaps, my stock Jeep with the tires inside the fenders would coat my trailer and the side of my Jeep like those pictures just driving a few miles down damp dirt roads - or just from the dirt in the snow...

 

[JeepinPete]

You are going to have to deal with the front tires too. In that slop at speed they will throw dirt up high enough to coat your trailer all by themselves. Don't know how much actual wheeling you plan in AK, but it this just a road trip, a set of factory side steps make a world of difference on the amount of dirt thrown up the side of the Jeep, even with tires poking past the fenders.
