If the spring has been weak(bearing slightly heavier body is very low), install rubber buffer. Can the auxiliary spring, relatively improve the body,improve the bearing capacity. If often run rough road (turbulence when the instantaneous pressure tends to make the suspension system damage)Install rubber buffer. Can enhance the damping effect, absorption transient pressure,protective dampers and suspension system. If often carrying heavy(damper and suspension system is more easy to aging)Install rubber buffer. Through the shock absorption, protection of dampers and suspension system, prolong the service life of the damping system. If the shock effect (no comfort, will causefatigue driving, no fun)Install rubber buffer.To improve the damping effect, enhance driving comfort, enjoy the driving pleasure. Using buffer principle, damping performance has improved significantly, damping effect can make the comfort up a notch. Non-bumpy asphalt road through a sharp turn, significantly improved stability. Restraint during the uneven pavement cars with shock to the body, thereby reducing the vibration noise of cars. Protection damper suspension system, extend the life of automobile shock absorber, damping spring seal to prevent damage due to excessive turbulence intensity caused. Installation is easy, No need to change any part of the vehicle. 2 x Car Buffer Power Cushion
