AZ9725520278 rubber support assembly is a shock-absorbing and buffer spare part for Sinotruk Howo heavy truck chassis. It is installed between frame and axle or leaf spring, used to absorb vibration and reduce rigid collision between metal components during vehicle running. The rubber support consists of high-strength metal skeleton and high-damping rubber compound. Through vulcanization integrated molding, it features good elasticity, compression resistance and aging resistance. It can effectively isolate chassis vibration, reduce noise transmission and protect frame and axle parts from impact damage under heavy load and bumpy road conditions. Each rubber support assembly undergoes strict compression test, static stiffness inspection and aging test before delivery. It helps reduce chassis abnormal noise and prolong service life of related connecting components. It is a common replacement part for chassis 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.
