Selling Services: Shock & Strut Replacement
The primary purpose of a shock absorber (or strut) is to control suspension movement. This is done by a piston moving fluid through a series of valves within the shock or strut housing. The valves control the damping rate of the shock throughout the travel of the piston. The damping characteristics are engineered to complement the suspension of each vehicle. Most shocks or struts are anything but linear in their damping effect. There is usually less resistance to movement in the jounce mode (wheel moving upward) than in rebound. This helps to improve the ride quality over bumps, while controlling the oscillations that would occur during rebound if the shock did not "tighten up." The damping effect may also be less during slow, short movements of the shock shaft. With larger or faster movements away from center, the resistance to movement will increase. This allows a smooth ride over small bumps, while maintaining ride control over larger bumps. The damping effect is crucial to maintaining vehicle control, especially during evasive maneuvers. The shock helps keep the wheel on the road. The stickiest tire in the world won't steer or stop a car if it's in the air. The shock or strut not only controls suspension movements over bumps, but also as the body of the car dives during braking, squats during acceleration and rolls during turns. A shock cannot add to the roll stiffness of the suspension as a sway bar does, but it can add to roll stiffness during transient maneuvers ... |
