Shocks are part of the support system on moving vehicles that helps to minimize wear and tear on essential components while also providing an enhanced level of comfort for passengers. Just about all kinds of shock absorbers work by utilizing the basic mechanics of hydraulics. There is not just one type of shocks that work for every type of vehicle. In fact, there are five distinct classifications for shocks.
Often, the shock absorber is filled with a fluid or gas that helps to absorb the movements of the support springs on the vehicle, while at the same time exerting pressure on the tires to keep them firmly on the road. The action of the shocks works in conjunction with the springs that also form part of the support system for most autos. Between the several components, it is possible to balance the load of the vehicle so the wear is even all the way around the wheelbase. This contributes to the degree of comfort that passengers will experience while riding in the vehicle.
Since there are many different types of vehicles, it should come as no surprise to find that there are shocks manufactured for different needs. Standard shocks are configured to fit on most passenger cars on the road today. Smaller trucks often will require use of heavy-duty shocks that provide a little more support when hauling larger loads than passenger cars.
