Product Description

Shock absorbers are critical components of a vehicles' suspension. They are designed to help to control the impact and rebound movement of the vehicle’s springs and suspension. Along with smoothening out bumps and vibrations, they key role of the shock absorber is to ensure the vehicle’s tires remain in contact with the ground at all times, which ensure the safest control and braking response from your car.

 


Shock absorbers are generally divided into cylinder shock absorber and strut.  They are similar on function, just different on design.

 

Shock absorbers are consumable item, just like tires, brake pads and engine oil.

Different between  Gas and Oil type shock absorbers
 
Hydraulic shock absorbers
 
Nowadays, hydraulic shock absorbers are rarely used in today's automotive industry. From a technical point of view, this type of damper is a poor solution, because the oil contains approximately 10% air. Under load, the air and oil molecules separate (foaming/cavitation), resulting in a noticeable drop in the damping force - on longer journeys on country roads and motorways, a loss of up to 35% damping force can be measured. That means the wheels provide poorer road holding; only after a break does the damper regain its full force and the vehicle its original driving performance.
 
Gas pressure shock absorbers
 
With gas pressure shock absorbers, this loss of damping force does not occur. The use of nitrogen ensures that the shock absorber oil is permanently under pressure, thereby preventing foaming, even under load. As a result, the driving performance of a car fitted with gas pressure shock absorbers can be precisely defined and remains reliably stable, whatever the situation; this constitutes a substantial bonus in terms of safety. Gas pressure shock absorbers are available with either mono- or twin-tube technology. The proven twin-tube system represents top-class technology at an attractive price. The mono-tube system, on the other hand, is the technology of choice in motor sports and on standard sports cars. The comparatively larger effective area of the working piston ensures greater damping force and better handling. Optimum discharge of thermal energy into the atmosphere means consistent high performance can be achieved and the sturdy design provides maximum safety reserves in flexible fitting conditions, e.g. inverted technology.
