Jeff,
I cannot really give you any comparison between the bushings and the rod ends, but I would imagine that the bushings would afford less harshness than the rod ends.
#1: these are sliders to improve stability and reinforce the adjusting sleeves (somewhat overkill, but overkill is good 8) ). Loosen to adjust camber.
#2: Camber adjusting sleeves. The control arms will arrive at OEM length (camber adjustment). Safe adjustment is 3/4inch out (neg), and 1/2 in (positive camber). That should satisfy everyone!
#3:Machined bushings for spindle pin.
#4: Offset bushings (delron).
#5: (which I forgot to lable, but you can see the line) Sway Bar mount. OEM location
Let me know if you have any other questions. These units weight 2.5 lbs more than the OEM control arms. They can be made lighter, but it starts adding to the material costs, since the thinner wall Chromoly is not 'standard spec' and has to be special ordered and is more than triple the cost. All the welding during the construction process is done clamped in a jig, so no pulling or warping occurs, everything is to exacting tolerances! The attachment 'rings' for the spindle pins are align bored and assemble perfectly!!
These are very well made units, and I believe that the cost is a reflection of that. I have not put much mileage on mine yet, so I can't really give too much info there, but from what i have driven they do not seem at all harsh.
