Smooth out worn, bouncy rides with the KYB shock absorber 344040, a front gas shock from KYB's Excel-G line. It's a direct-fit front replacement for many vehicles, including the 1995-2005 Chevrolet Blazer, 1992-2004 GMC Jimmy and 1982-2003 Chevrolet S10 — see the Buyer's Guide tab for the full list and engine details.

The Excel-G is designed to restore a vehicle's original ride control, stability, stopping, lane-change responsiveness and handling — not change it — earning KYB's OEA (Original Equipment for the Aftermarket) classification.

  • Nitrogen gas-charged, twin-tube design: built on KYB's OE assembly lines using the same OE-quality components, calibrated to restore original designed performance.
  • Triple lip fluid seal: helps reduce the chance of oil and gas leaking out.
  • Vehicle-specific, hand-assembled damping valves: manage tire contact, steering response and body movement, helping restore the designed control and handling of the listed applications.
  • Made in USA and recommended by KYB as an OEM replacement shock.
