Shock absorbers, or struts, play a very important part in every vehicle. It is the core part of every suspension system, which was why they must be periodically replaced to ensure superior performance. In the past, they were mainly composed of a cast iron rod, a sturdy coil spring that envelopes it, and finally the tube where this assembly are encased. The composition of modern version, however, is very much different. Several parts now make up a single absorber to ensure a smooth ride all throughout. So what goes on inside modern version that it seem to be doing a better job than old ones?
If in the past, shock absorbers are composed of less than five parts, most modern ones today is composed of more than ten parts, moving in unison to give you a smoother and quieter ride. Some of these are the valve, spring, main rod, piston rod, piston, tube, and the cap. Each of these parts has their own separate functions, but all working in a way that translates to a great suspension system.

The valve is assembled separately and also has its own small parts, each playing a role to allow it to function properly when it is finally assembled with other internal parts. The piston ring assembly is also another interior part which is composed of the assembled valve, piston rings and coil springs, piston rod, and cap. This assembly will be placed on the first working chamber of a shock absorber and helps in giving compression to the second working chamber.
The main coil spring is then placed inside the tube casing, along with another plethora of parts, then the main rod follows and is held in place by a series of hard plastic holders. This would now form the lower chamber of the shock absorber. The piston and valve assembly is then put on top of the second working chamber and sealed so that there will be no air inside to allow for maximum compression. This assembly would now work hand in hand, albeit with separate functions, to accord the passengers of a vehicle total convenience and comfort.
As you now know, there are a lot of small parts that are put inside a shock absorber tube. The biggest proof of this are the several chambers inside every shock absorber, and those chambers have also their own assembly of gadgets, all working together to give you a smooth ride all throughout.
