This DZ9100430011 longitudinal steering linkage is a core steering component for SHACMAN heavy trucks. It connects the steering gear and steering knuckle to transfer steering pushing and pulling force. Made of seamless thick-walled alloy steel pipe with forged ball joint assembly on both ends. High bending and tensile strength, resistant to deformation under bumpy and heavy-load conditions. Surface anti-rust coating provides reliable protection against mud, water and salt spray corrosion. Each rod undergoes dimensional, straightness and thread inspection before factory delivery. It solves steering shaking, loose steering and abnormal noise caused by worn steering linkage. Key replacement spare part for heavy truck steering system overhaul.
