The Hendrickson Auxiliary Load Spring Service Kit helps HN and HAULMAAX suspension systems manage added load as the truck moves closer to full capacity. Its progressive rate spring adds support as weight increases, helping reduce bottoming out and harsh impact through the chassis. The kit fits into the suspension spring pocket and includes high-strength flange hardware to keep the assembly properly seated during rough service conditions. The Hendrickson 64179-004 helps keep ride height, handling, and driver comfort in better balance under demanding loads.
