Automotive Shock Absorber Bushing is used to keep the car's tyres in permanent contact with the road, helping to provide optimum grip, when cornering and braking. Its main purpose is to serve as an interface between two parts, acting as a buffer and absorbing some of the energy produced by the interaction of two parts. Automotive Shock Absorber Bushing limits road noise and makes for a smoother ride. It separates two parts while allowing a limited amount of movement, thus minimizing vibration and even noise. This is designed to flex to build ride compliancy into the suspension. This also comes in a variety of forms.
