Bring back factory-level damping with the KYB shock absorber 341670, a nitrogen gas-charged rear Excel-G unit that drops in as a direct-fit replacement for the 2004-2006 Pontiac GTO. Part of KYB's Excel-G line — classified OEA (Original Equipment for the Aftermarket) — this KYB gas shock absorber is designed to restore the vehicle's originally engineered control and handling rather than change it.
As the KYB-recommended OEM replacement shock for performance cars, the Excel-G helps restore designed ride control, stability and handling on the GTO. Shocks wear as a set, so replacing both rear units together is recommended for balanced, even damping. Signs a shock may need replacing include excessive bouncing, nose dive, sway, or reduced ride control — diagnose the cause before replacing.
