Specifications

A leaking or worn suspension air spring can cause your truck to lose ride height and reduce its ability to absorb road impacts. This replacement supports vehicle weight through a flexible air bellows that moves with the suspension. Its construction includes a plastic lower plate and a three-point upper mounting arrangement. The component is intended for compatible Kenworth and Peterbilt rear air suspension systems. Before beginning your repair, compare 566.ER8864 with your existing component and check the plate dimensions, mounting pattern, and operating height.
