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.


Modern road transportation places high demands on the comfort and efficiency of automobiles. STEMCO (Stemco) company's mission is to "make our roads safer", knowing user satisfaction, easy and comfortable user experience, is the foundation of the product, and fully consider commercial vehicles in product design The demanding requirements of trucks and customers, such as its super-buffered air springs, use the materials and design of the load to provide industry-leading vibration damping, light weight and long service life. In addition, the unparalleled comfort performance design makes the super-buffer air spring reduce driving fatigue, reduce parts wear and tear, shorten the failure time, and thus improve safety performance.
