Japanese Car Shock Absorber 54302-8H625/334360 for 2001  X-Trail SUV T30

Suspension is a generic name for the connection equipment of force transmission between car body and car axle . Its function is relative motion between the axle and body and subject to vibration,

Shock absorber within the piston moves up and down ,the oil of the shock absorber cavity repeatedly fom one chamber after different pore flow into another cavity.The internal friction between the hole wall and the fluid between the friction and the oil molecules formed on the vibration damping force,vehicle vibration energy into the fluid heat emitted to the atmosphere,and then absorbed by the Shock absorber.

This working principle of shock absorber enable the car to be driven smoothly.
