6. If I do change the UCA's which would be better for my needs the Icon tubular uniball or one of the Dirt King versions?
From worst quality/performance to best.
SPC
Camburg Balljoint
Procomp
Camburg - ICON - Total Chaos tubular arms
Dirt King Bushing
Chaos Heim
Rokmen
Dirt King Heim
ICON Billet

interesting. I'm having a hard time figuring out the criteria this list is based on - at least the bottom half anyway. I'll be honest, I'm a Total Chaos fanboy because they are race proven on their factory team vehicles (do any of the others even race, bro?

) but.....
Sure, heim joints win out for the added adjustment they provide, however any non-4x4 specific alignment shop won't have a clue about how to adjust them (half the ones I've tried can't even figure out how to get a lifted vehicle close to spec regardless of what UCA's are on, and on more than one occasion, I've been told ridiculous things like "caster won't affect tire rub").
And I get the preference for uniball arms which come with a 'top cap', such as the Icons. In theory this should keep them from collecting debris in the spherical bearing - in practice though, the bottom of the bearing is still open, so they're going to get dirty anyway. Using a proper dry lubricant also helps in that dust won't stick to the bearing.
I had never heard of Rokmen before, though their little weather boots that cover the heims are genius!
those combined with the covered main bearing I would have thought would win out, but you've got the Icon billets at the top of the pile. the "pinch collar" adjustment that they use on all their adjustable suspension components scares the hell out of me. the strain and metal fatigue that this system imposes, I would think, is nothing short of a recipe for disaster. Furthermore, how often is the average person going to adjust the heims once they're installed? is this ability to make an "easy adjustment" really necessary, and does it warrant the risk over a traditional threaded tang? Seems to me like they're trying to solve a problem that doesn't really exist, and in doing so they are in fact introducing new points of failure into the mix.
