I guess that's sorta' what it is... It's called a uniball... Basically a 1" bore, 1. 75" diameter ball, teflon lined, spherical bearing..... Or ... ... a massive, oversized, heim joint that presses into the machined cup welded to the end of the track bar. They are commonly used in desert racing for lower/upper ball joints. Taking up the slack between the 3/4" bolt and the 1" bore there are two spacers which provide extra movement so that the assembly can swing without binding. It also relocates the joint so that the forces seen through the joint can be as perpendicular as possible to the bar correcting the problem with the OEM design. Still in prototype stages... . checking for clearance issues.....
