High Quality Truck Suspension Parts Thrust Rod Straight Truck Traction Bar AZ9725521174 9453300007 Lower Thrust Rod

The AZ9725521174 Lower Thrust Rod Assembly (Cast Straight Type) is a high-strength structural component in the rear suspension system of SINOTRUK heavy-duty commercial vehicles, including HOWO, HOHAN, and Steyr-based platforms. Designed as a primary load-bearing link between the chassis frame and rear axle, this forged-cast thrust rod ensures precise axle location under extreme longitudinal forces generated during acceleration, braking, and off-road operation.

Unlike welded tube designs, this version is manufactured using integrated casting technology with high-strength alloy steel, offering superior torsional rigidity, fatigue resistance, and geometric stability. It serves as the lower anchor point in balanced suspension systems, effectively preventing rear axle walk, reducing tire wear, and enhancing driving safety in 6×4 and 8×4 configurations.
