(888) 312-8812 Login SignupBuilt as a replacement for W01-358-8751, the Firestone Air Spring expands and contracts with a steady motion that absorbs rough terrain and uneven surfaces. Its robust plate profile seats securely inside the suspension assembly, helping the truck stay composed even when cargo weight changes throughout the day. Long-haul drivers, construction fleets, and regional carriers all benefit from the way it softens jarring movement without sacrificing responsiveness. For trucks needing an air spring that helps balance stability and comfort, the Firestone W013588709 brings a welcome upgrade to the suspension system.
