Goodyear® Goodyear air spring features
Goodyear® Goodyear air springs utilize the compressive elasticity of air, and are essentially different from metal springs such as leaf springs. It has excellent characteristics as a suspension spring. For example, the combined use with a control device keeps the height of the vehicle always constant or arbitrarily changed. It can also improve the vehicle's inclination by individually controlling the left and right air springs.
