A strut assembly is a crucial component of a vehicle's suspension system. It combines a shock absorber and a coil spring into a single unit, helping to support the vehicle's weight and absorb bumps from the road. This assembly plays a vital role in maintaining vehicle stability and comfort during driving. Strut assemblies are typically found in the front suspension of many cars and some rear suspensions. They help to control the vehicle's handling and improve ride quality by reducing vibrations and impacts from uneven surfaces. Regular inspection and maintenance of strut assemblies are important for safe driving and optimal vehicle performance.
