Product Introduction

The WG1642440086 shock absorber is a heavy-duty air suspension shock absorber (air bag shock type) used in SINOTRUK HOWO truck suspension systems. It is designed to replace traditional mechanical shock absorbers in certain cab or chassis suspension configurations.

This component combines air spring support + damping function, allowing it to absorb road vibrations more effectively while maintaining stable ride height under heavy load conditions. It improves driving comfort, reduces cab vibration, and enhances overall vehicle stability, especially in long-distance transport and rough road environments.

The structure typically includes a reinforced rubber air bag, metal mounting brackets, and an internal damping unit that works together with the vehicle’s air suspension system. When air pressure changes, the system adjusts height and cushioning force automatically, providing smoother and more controlled driving performance.

The WG1642440086 is widely used in HOWO, SHACMAN, and other heavy-duty truck platforms equipped with air suspension cab or seat systems.

Each unit is tested for air leakage, load performance, fatigue resistance, and sealing durability to ensure OEM-level reliability and long service life.
