This cab shock absorber is the front suspension hydraulic damping component for FAW Jiefang J6 heavy truck cab. It is installed on the front cab suspension. Its main function is to absorb vibration and impact transmitted from the chassis to the cab when driving on bumpy roads, reduce cab shaking and jitter, improve driver comfort and protect the cab mounting structure. Adopting precision hydraulic damping structure, seamless steel cylinder and high-performance sealing assembly, it maintains stable damping performance under long-haul heavy load, frequent vibration and temperature variation. Every shock absorber undergoes damping characteristic test and oil leakage inspection before delivery. It solves cab shaking, abnormal knocking noise and premature failure of cab suspension, serving as an essential replacement spare part for cab suspension maintenance.
