DZ9M189520008 DZ97259520620 Shacman X6000 Suspension Bridge Air Spring Bellow Air Spring Drive Axle Airbag Upgraded Airbag Assembly

The Air Spring Assembly (Part No. DZ97259520620) is a high-performance suspension component manufactured by Shaanxi Heavy Duty Automobile Co., Ltd. (SHACMAN) for use in the rear axle suspension systems of heavy-duty commercial trucks. Commonly referred to as an air bag or pneumatic spring, this part replaces traditional steel leaf springs with a flexible, air-filled rubber bladder that provides superior ride comfort, load leveling, and dynamic stability.

Designed specifically for modern long-haul transport applications, the DZ97259520620 is primarily used on SHACMAN’s premium truck models such as the X6000, X5000, and X3000 series, where driver comfort, cargo protection, and operational efficiency are critical. It plays a key role in isolating road shocks, reducing vibration transmission (NVH), and enabling automatic height adjustment for improved aerodynamics, loading/unloading convenience, and trailer coupling compatibility.
