This unit combines an air spring (replacing the coil spring) with a shock absorber into a single assembly for vehicles with air suspension. It provides both the load support and damping function, with ride height adjusted by air pressure. Failure leads to a sagging corner and loss of suspension function. We offer complete air suspension strut assemblies, integrating a durable air bladder with a matched shock absorber. Our units are direct replacements that restore both the load-leveling capability and the damping performance, ensuring the vehicle maintains its correct ride height and comfort.
