Upper control arms (Uca)

[jmb23]

Has anyone ever measured and compared how far the centerline of some of the aftermarket uca’s balljoint centerline is moved out? I worry about the SPC design being moveable and I don’t see any serrations to help it stay locked where you set it.

I would like an arm that has moved the centerline out at least 1/4” or 3/8” farther than stock arms. I have reached out to Readylift and they don’t know how far it is out over stock but that it is out farther. RC said theirs is the same distance.

Can't speak for the measurements, but the top ball joint nut isn't moving once torqued down. IIRC, it is a ~27-30mm nut torqued to like 200 ft-lb; there isn't enough force on it to cause any problems along those lines.
