A misalignment spacer does two things on a link suspension. The first and most important function is to allow additional room for the joint to pivot and let your suspension articulate. That comes simply from the shape of the misalignment spacer and the additional clearance it provides to the edge of the link tabs or brackets.
The second function is to reduce the internal diameter of the rod end, allowing you to use a smaller bolt.
Sold individually- get two for one rod end.
1.5" overall width with our heim joint.
