In addition to the significant weight of each axle, larger wheels and tires add even more tothe unsprung mass. The shock absorber for this task requires a different degree of damping on compression jounce and extension rebound than a shock absorber designed for a lightweight sports car with an independent suspension system.
For this reason, shock absorbers for light trucks are usually larger than those primarily used onpassenger cars. Gas-pressure monotube shock absorbers resist foaming of the oil inside the shock body and are therefore effective when used on pickup trucks and other vehicles designed for high-speed travel over rough roads. In off-road competition, for instance, the use of external oil reservoirs for the shock absorbers on trucks and SUVs not only provides more space for hot oil to expand into, but they also provide more cooling for oil inside the shock absorber to maintain more consistent damping while pounding across the desert.
Ground clearance and lift kits To make it easier to travel over rough roads, trucks have more ground clearance than standard automobiles. If this happens, the shocks will be damaged either by compressing too far and punching through their mounting points, extending too far and damaging their internal valving, or pulling apart their mounting rings. Likewise, the popular lowering of light trucks can result in bottoming of the shock on compression when hitting a bump, damaging the shock mounts and the shock absorber.
SUVs While the role of a shock absorber on a passenger car and a pickup truck is clear, the differences for sport utility vehicles might not be. Many SUVs now have independent front suspensions and some have fully independent front and rear suspension. News Jobs Contact Us. Knowledge Database - Shock Absorbers.

As you can see, with shock absorbers it uses some simple mechanics in an extremely efficient way. It deals with the energy in a way that benefits the car and it protects the rest of the suspension system from being damaged.
Both the suspension and the shock absorbers play an integral role in the way that your car not only works, but how it handles and how comfortable it is on the road. Without it, life would be a whole lot different and it would certainly not be as enjoyable as it should be. Our garages are ready to help you today. Get up to quotes for a suspension repair Your Suspension First, you need to understand that your suspension is actually made up of a number of different parts that, when put together, get to work on the steering of the vehicle as well as the ride comfort.

What does a fuel filter do? Here is the need of shock absorber arises, it is used to damp those oscillations which are made by the springs. A general shock absorber contains a perforated piston in a hydraulic chamber. The chamber is totally sealed and hence if piston has to make some movement the only way is to let the hydraulic liquid pass through it. As shown in the animated diagram. When a shock comes, piston has to move due to shock. When the piston moves than the hydraulic liquid in the shock absorber has to pass through it.
When the liquid is passed through the very tiny perforated holes in the piston the piston has to do some work against it.
