Product Details

The KYB Excel-G line is KYB’s OE replacement series, calibrated to return the vehicle to its original damping characteristics rather than change ride feel. Part number 3450006 uses a twin-tube gas-charged construction and OE-quality components to help maintain consistent rear suspension performance on the Chevrolet Tahoe, GMC Yukon, and GMC Yukon XL. This part cross-references Chevrolet 84082039 for the same application.

Common Symptoms This Shock Can Address

  • Excessive rear bounce after bumps
  • Reduced stability during lane changes or highway driving
  • Uneven tire contact caused by weak damping
  • Loose or unsettled rear ride control
  • Delayed response from the rear suspension over rough pavement
