2012 JKUR Dozer - Let the mods begin!

Actually, I guess that title is a little misleading. I've done a few smaller things already: Quadratec Ultimate floor liners, some Rugged Ridge grab handles here and there, and a Carolina Metal Masters custom black anodized billet grab handle with Ram Mounting Systems 1" ball mount (for iPhone / iPad mounting, which I love!). But the best mod so far has been the Star Fabricating Smart Door Stops. My driveway is on a pretty significant slope, so the doors were just a pain. Then my wife had emergency surgery mid-July to remove a massive tumor that had almost blocked, and had perforated her colon. So a door swinging back on her was just not going to be a good day. Yes, it was cancer, but she's doing fine now and tolerating the chemo exceptionally well. Now, back to the Jeep.

So, recently got some 37" MTR/Ks from vfireman309 over on Pirate 4x4 and settled on some black MB 72s to mount them on until I can save the money to go with either Hutchinsons or the HMMWV wheels from TrailWorthy Fab. Mock up is below.

Of course, that's at factory ride height. AEV DualSport SC 4.5" lift is on its way as of this morning and should be here Wednesday. It's anybody's guess when I'll be able to get to the installation, but it will be as soon as I can squeeze it in. I'll put up some pics whenever I do.

There will be upgrades to the suspension in the future - like I'm leaning heavily toward the Metalcloak control arms for their DuraJoint - but for now this made the most sense for me, all in all.

Although I haven't posted much here, I've spent a lot of time following different threads and learning everything I can from the information here, as well as on Pirate. Thanks to those who put the site up, and to all who have made it the quality resource that it is.

Looks worse in the lit up pic than it seems in person, but then I haven't driven behind it either. May have to just go ahead and add the second one.
Slick looking heep dude. We have similar taste in color lol. How hard where the tire wheel Combe to balance? Any idea what those rims wiegh? I have the same tires hiding in the rafters of the garage from the wife haha.
Thanks 08. I had a local shop mount and balance the tires so no problem for me lol. But if you look at that second pic of the brake light install, you can see a boat load of lead stickies inside that wheel! I got 4 of the tires from a guy on Pirate and they had ~ 5000 miles on them, so a little wear pattern showing up. The spare in that pic was a brand new tire and I think it's the worst! All new wheels, so shouldn't be any damage issues there. Can't find any info on the weight of the wheels. Thought I had saved the boxes and might find something on the shipping label, but they appear to be long gone. I'll have to ask the kids tomorrow if they can remember. Dad's memory is getting a little hazy. :)
LOVE the 3rd brake lite idea!!! Looks good!

Glad to hear your wife is doing good:thumbup:

God bless.

Thanks newmango. I thought it was kinda cool. What Trembley said about it being off-center got to bugging me worse, so I went ahead and rotated the spare, then added the second light.

And just for grins . . .

Nice Rig ---
Like the two lights versus the one in your back tire.
Looks awesome!
Thanks meshelz. One seemed like a good idea at the time, just didn't turn out as well as I imagined it, lol. I'm happier with the two.
What's a guy to do? It was the only one the dealer would let me order. :D
Found it! Looking good so far! Glad to hear your wife is doing good. Looking forward to meeting with you one of these days. For some reason I was thinking you were out of Lodi but apparently that is Cambo. I think the only run I got planned coming up anytime soon is Slick Rock the beginning of May. That first weekend I believe. If you ever go out to Carnegie again give me a shout its right down the road. Frank Raines isnt that far either but honestly there is nothing challenging there unless it rains. Their black diamond trails I did in 2wd. Same goes for if you ever need help wrenching but from the sounds of it your daughters got you covered.
best wishes for the wires recovery and recoup

second how does it ride now? how do you like the 37's and its ride?

Im looking to do the same thing, mine came with 35's from the dealer so I have no idea how it is supposed to ride stock. I hear its the same or better with a real lift anyhow (just has spacers on mine now)

AEV claims it's a better ride than stock. Hard for me to say where the fault lies - tires or suspension - but that hasn't been my experience. Never had 37s before so maybe it's just part of having that much more sidewall squirming around, but it can be kind of a handful to keep it pointing where you want it. I've nut & bolted it twice since I installed the lift so i know everything is torqued to spec and nothing is moving around on me. Honestly, if I were going to make this my primary daily driver, I'd probably go back to 35s. But IMO the wheelbase of the JKU makes 37s a better choice for the trails I want to run. It does brake crazy flat though. There's hardly any nose dive at all. And it corners fairly flat for a lifted rig as well. Really my only issue is that it's just kind of hard to keep in a straight line. Also, I have the 4.10s so it does OK on the factory gears. I'm thinking pretty hard about going to 5.13s though, to get things back down to where they belong.

Edit: after several months on the used MTR/Ks I bought first, I found myself needing tires for my expo trailer and picked up 3 new 37x12.50R17 MTR/Ks, swapped the brand new spare to the ground along with the three new ones, put one of the used ones at the spare position and dedicated the remaining three used ones to the trailer. (It gets its own spare.) Suddenly it drives like new with no wandering, etc. My conclusion is that the problems I described above were actually caused by the wear pattern on the used tires. In addition, the extra weight I have add in bumpers, gear, and armor since then have made the AEV suspension smooth out like butter. Couldn't be happier with the system now.

Ok, it is fairly common to have a slight pull or wander in lifted vehicles.
This happens due to parts wearing more qiuckly and flexing under pressure.

If you want to get rid of this there are a few simple things you can do.

1.) North Ridge 4x4 Grade 8 JK Bolt Kit
2.) Replace Stock Track Bar with either Rock Krawler or Synergy Suspension
3.) Replace Tie Rod with either Rock Krawler or Synergy Suspension
4.) Once your vehicle gets a few miles on it upgraded ball and u-joints.
Ive done nearly all of that and mine still pulls to the right slightly but ive learned to live with it. My tire pressure may not be entirely equal either.
thanks for the feedback guys.
Nice rig, i have the same trailer, boy are those heavy.
Thanks Bill. I love the trailer. It's just the right size IMO and the track width is virtually identical to the JK. Also, its weight rating is perfect for the trailer weight rating on my JK (Max Tow Pkg). I've not pulled it a lot with the tarp and bows on, but without them, I hardly know it's behind me. I know lots of folks say that about their 34' goosenecks, and whatever, but it's true about this. I can forget it's behind me on the freeway -- which is an especially bad thing here in CA, as you know.

It is a little heavy to move around by myself, but I can do it if it's not on too much of a slope. I've been making plans for putting it on a diet though because I intend on adapting it to expedition / camping use, but also leaving it so I can also use it as a utility trailer. I'm going to lose the surge brakes and go electric, so that's a fair amount of weight after the surge controller and axle come out. From what I've read, the axle alone is a beast. A standard 3500# axle with electric brakes and e-brake option should be significantly lighter.

Unlike many, it seems, I like the pintle hitch, so I'll be converting it to an A1 style lunette instead of the A2 brake controller. I'm also planning on reworking the tongue in order to make it a true dump trailer. Love that function, but the geometry of the A-frame attachment is not really designed for it and will eventually break with the twisting stress applied as the trailer rocks backward.

I already have a utility type camper shell with a nearly full length tool box down one side. Scored it cheap, and hauled it home on this trailer. It should work out well for enclosing the trailer but still be removable. And the tool box will make a good kitchen. I've been putting in overtime on Google Sketchup doing drawings and planning it out in my head and on virtual paper. It has worked out well to see what works and what doesn't before I go spending a bunch of money outfitting / upfitting it. I'll post up some pics of what I'm thinking and let people criticize, er, I mean critique the plan. :D


Here are a few views of what I'm scheming . . .

That tube looking thing at the top of the shell is representative of a rolled up awning.

Somebody's gonna say, "Beadlocks on a trailer? What's up with that?!" It's all about uniformity and versatility. I plan on having 8 identical tire/wheel combos (both Jeep and trailer have their own spare). That should get me out of just about any tire trouble I can foresee getting into, and also cover me if I want to use the trailer with another vehicle.

And now partially setup . . .

That's a modified military surplus aluminum boarding ladder on the tailgate. Of course the tailgate chains have to be modified also in order to allow the tailgate to lay flat. Also, don't have a view drawn yet with the spare tire carrier in it's open position, but it's a 90* swing-out design.

Inside, you can see a cot hinged to the side of the shell. It is designed to fold in half lengthwise so that it can stow against the side of the shell, out of the way. When it's down, there is still plenty of room for one (or two really friendly people) to bed down on a foam or air mattress in the bed of the trailer.

The shelf, that forms the kitchen counter will stow inside the trailer and fit's nicely against the back side of the tool box, so it won't take up any appreciable space. The sink just sits in a hole in the counter-top so it can be removed and stowed in a box with other items, maximizing space. It will simply drain into a 5 gal. bucket.

No, that's not a microwave in the toolbox, it's a propane camp oven made by Camp Chef. The red and silver things are a couple of different stove models also by Camp Chef -- a 2 burner, and a 3 burner that has a center grill section.

I'm thinking of mounting an outdoor shower sprayer like you'd find on a slide-in camper or travel trailer in the space to the left of the toolbox. I might also mount a polyethylene potable water tank to the bottom of the frame, above the axle like some of the generator trailers had mounted fuel tanks. That way the shower sprayer could provide running water to the kitchen sink for food prep and/or cleanup.

And with the Roof-Top Tent deployed . . .

It's hard to see, but I've designed in a UHMW turntable so that I can stow and haul the tent lengthwise to the trailer, but then if I want I can pivot it 90* in order to deploy it to the rear of the trailer instead of the side. This will obviously allow the trailer entry to be sheltered in the event of inclement weather, or if the folks in the tent just want to be less separated from the folk(s) in the trailer, or even in the vestibule, if there is a need for that much sleeping space. Those are solar panels out front.

Constructive comments are welcomed. Help me think of what I haven't thought of.

Looks good! You put a lot of thought in this and it looks great. There are a ton of trailer builds over on expeditionportal.com.

Thanks Cambo. Yeah, it kind of consumed me for a little while there. I've looked at a LOT of those builds on Expedition Portal for inspiration and ideas, as well as what doesn't really fit my purposes or style (or budget! :)). I imagine this will be a slow buildup doing just the bare essentials and then adding a little as it becomes necessary. But at least I'll have a plan to go by.
