These spacers come in a pair and are used for a heim joint that is not perfectly inline with the hole and will move farther than a normal spacer will allow. This spacer allows the heim joint to travel farther to the left and right than normal. This is a very sturdy design built and manufactured at Day Racing Products.
 
Increase available articulation at compatible rod-end joints with a high-misalignment spacer. Choose the correct size to match the joint, fastener, and mounting width.
