Shacman Heavy Truck Front Spring Front Bracket SZ970000021

The SZ970000021 Front Spring Front Bracket plays a critical role in front axle stability, steer vehicle geometry, and load bearing. As the primary forward mounting point for the front leaf spring assembly, this Shacman front spring bracket holds the front leaf spring pin in rigid alignment, enduring intense vertical impacts, braking torque, and lateral cornering forces.

Manufactured in ISO9001-certified facilities using high-strength cast steel or ductile iron, the SZ970000021 bracket offers high tensile rigidity and fatigue resistance under heavy haulage conditions. Replacing a cracked, worn, or deformed front spring hanger with a brand-new SZ970000021 unit restores proper front axle positioning, stops chassis knocking, and prevents irregular front steer tire wear.
