What is a strut?

A strut is a shock absorber mounted inside of a spring in a vehicle to absorb shocks for a smoother ride and to provide support to the vehicle's suspension. Struts are attached to the anti-sway bar to stabilize the vehicle.

Struts are mounted on both sides on the front of a vehicle near the tires. Some vehicles also have rear struts. The struts are attached on both ends of the anti-sway bar, which stretches across the vehicle for stability. Together, the struts and anti-sway bar form the vehicle suspension system, which dampens sudden movements and transfers movements of one side of the car across the vehicle for a smooth ride.
