As new, OE-matched components (covering two key OE codes: 20443615, 20443617), these SW damping adjustment valves are exclusively engineered for Volvo trucks equipped with ISRI seats. They directly resolve critical issues from faulty valves: ineffective shock absorption, unstable seat damping, or rough ride comfort that impacts driver fatigue. Built to ISRI’s strict standards with fresh, durable materials, the valves restore smooth, responsive damping control, eliminate costly seat overhauls, and simplify maintenance for Volvo truck owners and fleets.
