For 04-20 Toyota Sienna FWD Front Struts w/ Coil Spring+Rear Shock Absorbers

A shock absorber is a mechanical device designed to smooth out or damp shock impulse, and convert kinetic energy to another form of energy. It is used in conjunction with cushions and springs. An automobile shock absorber contains spring-loaded check valves and orifices to control the flow of oil through an internal piston. Strut assemblies include all the components required for strut replacement in a single, fully-assembled unit. This fully integrated design helps reduce installation time, eliminating the need for a spring compressor, ensuring a complete repair.
