Jim, those control arms are made by THE CAMBERKING. His name is Jim Wong and his shop is in Plantsville CT. Good workmanship with quality materials.
Is the center upper most control arm curved, similar to OEM so as not to hit the sway bar linkage? I made my own in the rear using chromoly tubing and with Aurora rod ends on the Limited which is also lowered about 1.4 inches on a H & R set up.
He makes a camber control arm for the front also, but I do not really like it as it moves the caster adjustment along with the camber. I've returned the control arms to him, now I'm trying to get a refund.
