What are struts?


While they share similar roles, struts and shocks are not interchangeable parts. Struts are a structural part of the suspension system and are mounted to the chassis of the vehicle. The main job of the strut is to absorb the impact created by bouncing and dipping on the road. In addition, the strut provides structural support of the vehicle's suspension and holds the tire in the properly aligned position. Struts are composed of only two parts: the shock absorber and the spring. The spring is almost always in a coil shape. In turn, the shock absorber is fitted down the middle coil spring. It’s important to note that not all cars and trucks have struts. Different suspension designs will use separate springs and shock absorbers. It's important to have struts inspected annually to check for leaks or prevent long-term damage. Bring your vehicle to a trusted ASE certified mechanic for service!
