The truck torsion bar drop arm bracket bushing is a key buffer component connecting the drop arm to the chassis, made of highly elastic and wear-resistant rubber. It effectively absorbs road impacts and vibrations, reduces direct friction and noise between metal parts, and ensures smooth drop arm movement. Its function is to protect the torsion bar system, improve driving stability and ride comfort, and extend the service life of related chassis components. Regular inspection and replacement of this bushing are crucial for maintaining vehicle handling and safety.
