As a genuine Firestone Airide replacement, this unit matches the load pressure requirements of the original setup, keeping the frame height consistent even when hauling heavy cargo. The durable rubber and fabric construction flexes millions of times without cracking, while the crimped bead plates hold air pressure tight against the chassis. This Firestone W01-358-9321 single unit replaces a leaking or blown bag to get the truck back to a safe driving height.
