High Misalignment Series Spacers
Standard rod end spacers should only be used when the width of the ball is too narrow for an application. If more misalignment is required, high misalignment spacers should be used. They allow for more misalignment by continuing the spherical diameter of the ball and allowing the edge of the ball to rotate into the body.
The I.D. of the high misalignment spacer is less than the original I.D. of the rod end, so a smaller bolt is required.
