Spherical bearing, not helm joint.
Those arms look like an exact copy of SPC/Moog/etc.
The Whitelines are the same arms with the bearing pressed out and “synthetic elastomer bushings” at the inner joint for SCCA compliance.
Spherical bearing is a normal type of joint used in automotive suspension, not some huge performance upgrade. “synthetic elastomer bushings” tend to puke out every so often and have to be maintained, in my experience.
