OEM 42052982 4697041 Heavy duty truck air suspension shock absorber for IVECO chassis TURBOTECH/TURBOSTAR series with warranty

"Airbag structure": Generally, an airbag made of high-strength rubber is used as the elastic element. Compressed air is filled inside the airbag. It can automatically adjust the air pressure inside the airbag according to the load changes during vehicle driving, thereby maintaining the stability of the vehicle body height and providing good shock absorption effect.
"Shock absorber cylinder and piston assembly": The shock absorber cylinder cooperating with the airbag contains parts such as a piston and a piston rod. The piston moves up and down inside the shock absorber cylinder. The flow of oil is controlled through valves and small holes on the piston to generate damping force and slow down the vibration and impact of the vehicle. The piston rod connects the airbag and the vehicle's suspension system to transmit force and displacement.
