Quick Overview
These have a 3/8" center pin hole machined into them to allow you to bolt them into the spring pack with a new center pin (available in related items). That way they can not kick out. Also being steel you can weld them to a spring perch if you desire. These will not crack like cheaper aluminum versions. Call to discuss your suspension setup if you don't know what degree you need. Degree is stamped into the face for easy reference.
