A strut assembly typically consists of three main parts: a coil spring, a shock absorber, and a strut mount. The coil spring serves to support the weight of the vehicle and absorb impacts from bumps in the road. The shock absorber helps dampen these bumps to reduce vibration transferred through the suspension system. The mount connects all of the components and helps to keep them in place. Other components such as dust boots, bump stops, and suspension insulators may also be included in the strut assembly.
