Fk high-misalignment bushings are designed to increase the misalignment angle and reduce the hole size in your bearing. They will permit the rod end to swivel through a much wider arc to provide you with a more versatile mechanism. Additionally, you'll also receive a safer means of mounting spherical rod ends with a high angle of incidence with FK high-misalignment bushings. The bushings are made from 17-4 pH stainless steel to last.
