What shocks and struts do? SHOCKS KEEP YOUR VEHICLE STABLE AND YOU IN CONTROL They keep the tires from bouncing which causes loss of road contact and they also keep the vehicle body weight from shifting and rolling which causes a loss of vehicle control and handling.. When shocks and struts are working well, the vehicle maintains traction on the road and has the optimum stability in every driving condition: stopping, turning, swerving, over bumps and potholes.
A shock or a strut operate the same but mount differently. Each of the four tires has either a shock or strut connected to that corner’s suspension and vehicle body or frame. They are hydraulic cylinders that provide motion damping by restricting fluid flow through a series of internal valves. As the wheel and body moves up and down, the shock valving slows and stabilizes the movements.
