These Navistar-specific shims are designed for use on the lateral link of Navistar "Corporate" 6x4 air suspensions to center the axle with the frame rails. They also adjust thrust angle and toe when placed between the spring hanger and spring. Supplied six per box, they offer a tailored solution for alignment tasks on that air-suspension application.
