High misalignment spacers increase misalignment by continuing the spherical diameter of the ball and allowing the edge of the ball to rotate into the body of the rod end. This allows greater articulation, more suspension travel, and longer life of the rod end.
The main body of this rod end is 100% 4340 chromoly and then finished with a zinc coating, the ball is made out of AISI 52100 material and then hard chrome-plated for a tough finish. The liner is made out of a teflon. Comes with the jam nut.
