WG9725520389 Center Bolt is an important fastening component for Sinotruk heavy truck leaf spring assembly. It tightly connects each leaf of the leaf spring together, keeps the plates aligned and transmits driving and braking force. Long‑term heavy‑load driving on bumpy roads may cause thread wear, bolt elongation or even fracture. Broken center bolt will lead to dislocation of spring plates, which seriously affects driving safety. It is a necessary replacement spare part for heavy truck suspension maintenance.
