KYB shock absorbers, struts, coil springs, strut mounts and dust protection kits. Together with the KYB valving system, the gas pressure provides a direct response with excellent damping performance while significantly reducing the air permeation or foaming that commonly occurs in shock absorbers and is responsible for their effectiveness starting to deteriorate, even after just a few minutes of use. A vehicle's suspension is made up of three components: the tire, the spring and the shock absorber. All three components must be in good working order to ensure proper tire-road contact. The basic function of a shock absorber is to maintain a vehicle's tires in contact with the ground.
