It dampens road vibrations and controls wheel movement to prevent excessive bouncing that can damage cargo and wear out suspension parts. With a 1-3/8″ bore and 5.37″ stroke, it provides consistent damping on Hendrickson HK, HS, and HT series models. Replace it when shocks leak or ride quality worsens to restore stability and protect the trailer’s structure.
