Shaanxi Automobile Shacman Truck Parts Rear Leaf Spring Bracket HD90149520027

The HD90149520027 Rear Leaf Spring Bracket is a critical load-bearing component in the rear suspension system of SHACMAN Daimler series heavy-duty trucks. As a primary structural interface between the chassis frame and rear axle assembly, this bracket ensures reliable transmission of vehicle weight and dynamic road loads from the leaf spring to the rear bridge and frame rails.

Engineered for extreme durability, the HD90149520027 is manufactured from high-strength ductile cast iron (QT-grade) or cast steel, combining excellent fatigue resistance with superior impact toughness. Its precision design allows secure multi-point mounting on the frame rail, effectively preventing longitudinal and lateral displacement of the rear axle under rough road conditions.
