Blaine is not the one who needs to feel safe.... that is my decision since its my rig. That being said, between the quality of Blaine's welding skills and the size of the material and joints we are using, I am not worried about it.


The question does beg some discussion tho as it implies the previous set up I had was safe which is not necessarily the case. The brackets had so much bind in them that they were breaking and at one point, I did have a 3 link up front after I snapped and upper off while off roading. The radius arm also had a propensity to unload on steep climbs which always made me nervous so yah, safe is relative.

Not to derail anything, but is there any way to prevent a front radius arm from unloading? Aside from replacing the arms lol?

"LCOG" isn't cheap and it certainly isn't easy. If you think so, you are doing it wrong. If you aren't willing to put in the effort, don't label your build "LCOG". You are just a cheap ******bag.

While it may be your decision Robert, if I thought there was shred of inherent danger in the suspension design, it wouldn't leave my driveway.

I don't make that distinction. It's either safe or it isn't. I don't build "safe on the trail" one way and "safe on the highway" another.

What most don't understand is our roads to the trails and the speeds we travel them at place far more stress on stuff than the highway ever will.

I'm aware of a suck-down winch, however I really don't feel like running my nice synthetic rope over my bumper, nor do I feel like trying to shove a small winch out of the way somewhere to do the task.

With limit straps at either end of my front axle, I don't see one in the center being too much of a help.

That's why it's in your driveway and not mine.

Check out the way Blaine did it on the TJ featured in CRAWL mag. someone has a link for that thread. its pretty ingenious. or was it ingenuous, or igneous I don't know.

could be wrong but i dont see the straps at the axle helping either..they limit down travel so you dont drop your springs mostly. so if set up to articulate, when going up a steep climb seems it will still unload both sides till it reaches the limit straps end.witch could be a foot difference than ride hight..seems logical to me.could be scary it seems.
when sucked down with a winch you can release it and tighten it when you want,if set up to do that i suppose.
i will let ya know in a couple weeks after i hit my normal hills with radius arms installed

If people could see how Jon's Jeep performs and how much stress he puts on it. They would understand, maybe.

At the end of the day I Figure it takes far more than a physics class and a welder to design these suspensions. Understanding the force what direction the force is being applied how that will effect the weight and the center of gravity and how different angles of approach...I mean seriously has anyone sat down and listed out when you design your suspension you have to compensate for and list it out? short versus long height I think a lot of regular joes..Ok ME in the past took for granted what 50 years of off road experience Baja 1000 and other races have taught people in the fabrication industry. ok no more wasting space for tday

You don't learn any of this in physics. There is almost nothing in physics that's actually the core of physics that has to do with suspension. Now dealing with electronics, that's different. But there are no physics equations, to my knowledge, that deal with suspension. If there was, I would understand what Blaine is talking about, but I don't.

Thanks Tim, I spent about an hour out there this evening and solved the frame side trackbar issue in a fairly simple and clever fashion. I'll get a pic up tomorrow so the folks have something to snivel about.

The frame end was an RE style rod end with the single shear bolt up through the mount. That also kept it far enough back that the diff cover slammed into it before the Currie bumpstops touched. Afterwards, I took the lower 1" spacer Currie supplies out from under the urethane and was able to make the upper and lower contact each other quite nicely and turn the bolt horizontal in a double shear mount.
