It softens and kills vibrations received by a car body from the wheels when riding on uneven surfaces.Masuma coil springs are made from finished steel in compliance with heating, winding, hardening, and tempering technologies standards. These coil springs also get surface reinforcement against surface fatigue. Materials and technologies used by Masuma in coil springs production allow for car suspension life-time incensement in heavy road conditions
