Product Introduction
The WG9100680004 rear shock absorber is a heavy-duty suspension damping component designed for SINOTRUK HOWO truck rear axle systems. It is mainly used to absorb road vibration and reduce impact transferred from the chassis during vehicle operation, improving vehicle stability, ride comfort, and suspension system performance under heavy-load conditions.
This shock absorber is manufactured with a high-strength steel body, hydraulic damping structure, and durable sealing components to ensure stable performance during continuous heavy-duty operation. The internal hydraulic damping mechanism effectively converts vibration energy into heat energy, reducing rear axle oscillation and improving suspension stability during long-haul transportation and construction applications.
According to supplier specifications, WG9100680004 is commonly used in SINOTRUK HOWO and HOWO A7 truck suspension systems and is suitable for heavy-duty logistics trucks, dump trucks, tractor trucks, and construction transport vehicles.
Industry discussions note that rear shock absorbers play an important role in controlling axle movement, reducing tire bounce, and maintaining driving stability during heavy-load operation.
The product is engineered according to OEM specifications for direct-fit installation and reliable compatibility with original HOWO chassis systems. Each unit undergoes damping performance testing, durability inspection, dimensional verification, and sealing tests before shipment to ensure OEM-level quality and long service life.
