AZ9925410121 front axle shock absorber is a hydraulic damping spare part for Sinotruk Howo heavy truck front suspension system. It is mounted between the front axle and the frame, working together with leaf springs to absorb vibration and impact generated by uneven road surfaces during driving. It effectively suppresses spring rebound oscillation, reduces body shaking, stabilizes wheel contact with the ground, improves driving comfort and guarantees braking and steering safety. This shock absorber adopts high-strength outer cylinder, precision piston assembly and high-performance oil seal. It features stable damping force, good sealing property and anti-aging performance, adapting to heavy load, bumpy mountain roads and long-distance continuous transportation. Each shock absorber undergoes strict pressure test, damping performance inspection and fatigue cycle test before delivery to prevent oil leakage, damping failure and abnormal noise. It is a necessary replacement part for front suspension maintenance. We maintain sufficient inventory and stable bulk supply for repair workshops, fleet operators, auto spare parts dealers and global cross-border export customers.
