NO.Package including shocks only,NO springs/mounts/rubbers/bushings/bolts ( PS: it's included by Complete struts) Why did I only receive 2 pcs shock struts when I bought 4 pcs actually? Sometimes these 4 pcs shocks you bought are too big and heavy, so we sent them to you in 2 separate packages. The other package is on its way to your house, please wait patiently, you will receive it soonest. What about the difference between shocks and complete struts? The structure of the shock absorber is different from that of complete spring struts assembly : Shocks is only a part of the assembly; the complete spring struts assembly consists of a shock absorber,spring,washer,spring top rubber and nut. What will happen if these worn shock absorbers are not replaced? Shock absorber is an integral part of vehicle suspension system. They prevent premature wearing of suspension parts and tires. If the shock absorber is damaged, the braking and steering stability of the vehicle will be endangered.
