As part of KYB's Excel-G line, this gas shock absorber is calibrated to restore original ride control, stability and handling rather than change it, earning KYB's OEA (Original Equipment for the Aftermarket) classification.
Worn shocks can show up as excessive bounce, nose-dive under braking or poor lane-change response; if the original shock is the cause, this Excel-G replaces it.
