Huh....what's all more exposed with the bent-style lower arms? Nothing on the 100-series. Nothing on the 80-series. The lower shock mounts are well tucked away on these trucks. The drive shaft is a bit more of a target though that gets addressed two ways.

1. With only the drive shaft to worry about clearance-wise, picking the right line is easier. With the bent arms one doesn't need to worry about placement hardly ever.
2. Put on a heavier tubed rear drive shaft...which I have for both vehicles.

You have never hung on an arm? Dear Lord....the folks in the 80 forum would wonder what trails you're running. :D Also keep in mind here we're talking in the FJC forum where these guys are experts at arm hangin'. :D

I don't want my arms lifting the axle over rocks and ledges as you've pointed out. I want my TIRE to lift the axle up and over. The picture of the ice chest above illustrates the merits of this.

I had the larger steel on my '93's arms along with the larger stock arms that the 93-94 had over the 95+. Bent those as well.

Tell you what....I stand by the merits of these angled arms. On the trail I have no more worries. They clear the stuff just like 4WD Toy Mag reported on the Rubicon.

I wish I had them when I was here. Climbing three ledges at 4 of the wheels at once, fully locked, hopping, and you can see the DS arm mount is cleared while I'm hopping on the arm which stops my progress. With the new arms I'd a driven right up as nothing would have hit.

I recognize that step! In the background, about where the 40 is, there was a notch to go thru. It was the first time I employed my HD arms, and all they suffered was a loss of powdercoat. The 100 behind me on that run didn't quite make the turn and got wedged between two rocks, taking rr qtr damage and requiring excavation for removal. I think he also removed his e-locker actuator.

Never hung on a rear arm, many times on the frame bracket, a couple of times front arms. Have some seat time in FJC's, including on that trail, have spotted a ton of them and don't remember ever hanging one on the arm?

Really don't care what trails people think I run?:confused:

When we ran it in Aug, made that step with only rear locker, last month with the trail team, ran it no spotter, unlocked, walked right up it. I don't think I locked until we started playing on the big steps, rocks at the upper end, 37's rock!:D

I doubt Chris attempted the same line I did in that pic. I could have went to the left more and not struggled. The right side has the taller climbs.
 
No, John - he actually got hung up further back, right where you break left into that set of steps. Last time I was there, the right was easier. We should have some pics on our Payette 08 run thread. Oh and we took 3 FJCs through on the right and left lines, no problems, no arm contact:meh:. The only thing that hit was the front tie-down rings on an 80 who took the tallest part of that step straight on - after beating the rock a couple of times:hillbilly:
 
He busted here? How?

Don't know, only saw the aftermath, but somehow got stuck sideways, front bumper on the rock to driver, rear quarter/bumper on the rock to the passengers.

That step that John is on is easier now. On the Sept,07 cleanup run, Maureen broke a little piece or rock off with the Gibson rig. As the bumper slid up the lip, a dinner plate sided slab peeled off, when she tried to move forward it would lever up lifting the the front end. :hillbilly:

Thats the spot! Chris went up to the left to after this, I think looking to take what apppeared to be a bypass around those steps. If you look up to the left of those steps, on the other side of the rocks, it looks like the remnants of a dirt road. That was July '06, and everyone was fighting that spot then - trail was wet too. From what I've seen in the last year, Chris gave up taking bypasses:bounce::grinpimp:.

GOTCHA! Ya, those steps were tough for many of us. My other buddy broke climbing them in his 100. I told him he needs an ARB bad. He did everything but, and bang it went. When I was climbing I was hopping and clawing and no breakage. I was gental however.

All I needed to climb easily here was:

The new arms
or
Another 1" of suspension lift
or
An 80 w'35's and 4" lift (or greater)

At 3" and 315's I was just shy of clearing. OR, I should have moved over a foot to the left where it's easier. But NO...can't do that! :D

OK, now that the AZ crew has weighed in, lets get back on topic. My advice would be to look at the construction of the arms, make sure they are at least 1/4" steel, and I would lean toward round as opposed to square tubing (personal preference and stronger). As far as ends, I have the Rubicon Express flex joints, and don't see that I'm really gaining anything significant with my OME medium set up and 315x75x16 Nittos. The rubber/poly bushings will probably give you the same effective travel/flex with most suspension options. But NOTE, the brackets are forward and weaker than the arms and are the first point of contact. These also need to be reinforced as part of the upgrade. My$0.02 from my FJC experience.

Oh, and 4+ is built for Man-A-Fre locally here in AZ and is simply some stout stuff.
 
...But NOTE, the brackets are forward and weaker than the arms and are the first point of contact. These also need to be reinforced as part of the upgrade...

OK, what's up with that? When you look at the underbelly of the FJC, the LCA brackets just scream "scrape me off on a rock". Surely, they could have been imbedded in the frame or the bracket moved just inside the frame member to protect it. Just venting. :meh:
 
True, true. I was just venting.

Oh, BTW, you are my UZJ100 hero. When my wife let's me upgrade to her 2004 UZJ100, I'm gonna take your build list to my local mechanic and say "make this UZJ100 look like that UZJ100". :cheers:

Sweet! Thanks sir! You will enjoy that 100!

OK to vent...the mount location sucks on the FJC, the 100 and the 80. :mad:
 
I don't mean to argue, but if you lift the truck,it is impossible to regain the stock positive caster w/o aftermarket UCA's. You can get kinda close, as I did first after installing my lift kit. But the tires stated cupping and the handling was diminished. After the Total Chaos arms, the difference was remarkable. It now drives the way it did when I bought it.

Hasn't been the case for almost everyone. 100K miles and no cupping. Handles great is the consensus of after-lift posts.

Maybe the upper arms make a small improvement. That's great. To say that our tires will cup and handling is not that good is simply the opposite of the reports.

This thread was actually discussing rear arms.

What are you talking about? The 100 or the FJC?
It would be helpful for everyone to keep to the topic- FJC LCA's

Let's start a new thread for FJC uca's to help future searches and avoid confusion

If you are talking about your 100 series, than this is the wrong section.

Ha! Duh...I have a thread on this in the 100 section. Ya, this is the FJC thread. Fart! :D
 
so you have 100,000 miles on FJC uca's? Then it would help if you said which ones and the experience of not cupping, etc would be of benefit to the FJC owners
