For Shacman Heavy-Duty Truck Parts Balance Shaft Bracket Support DZ97259520401

The DZ97259520401 Balance Shaft Bracket is a core cast structural component in the rear tandem suspension system of SHACMAN Delong X3000, X5000, M3000S, and F3000 series heavy-duty commercial vehicles. As the primary mounting interface between the chassis frame and the balance shaft assembly, this bracket bears the majority of the vehicle’s rear axle load and plays a pivotal role in dynamic weight distribution across dual drive axles.

Manufactured from high-strength ductile cast iron (QT-series), this heavy-duty bracket delivers exceptional yield strength, fatigue resistance, and torsional rigidity. Its robust design ensures reliable performance under extreme operating conditions such as mining, construction, bulk hauling, and long-haul freight transport.

Integrated with HanDe (Hande) 13T/16T double-reduction axles or MAN technology-based bridges, the DZ97259520401 enables optimal load balancing on uneven terrain, improving traction, reducing tire wear, and enhancing overall vehicle stability.
