Firestone Air Spring

The Firestone Air Spring offers controlled suspension movement for trucks that experience fluctuating load conditions throughout the day. With a design height range of 15 to 17 inches, this spring gives the suspension room to adapt to heavier trailers, uneven roads, and steep approaches. Its assembly weight of 15.9 pounds reflects a robust structure capable of supporting consistent vertical stability while still offering responsive travel. The Firestone W013589192 helps reduce harsh impacts transferred into the cab, contributing to a smoother experience for operators running long or varied routes.
