KYB Excel-G Front Shock Absorber

KYB Excel-G 344380 is a nitrogen gas-charged, twin-tube suspension shock absorber built to restore original ride control on select GM full-size trucks. It is an OE-style replacement for front suspension service on the Chevrolet Silverado 1500 and GMC Sierra 1500, with fitment covering 1999-2007 applications listed below.

Key Features

  • KYB recommended OEM replacement shock for front suspension service
  • Restores designed control, stability, stopping response, lane-change response, and handling
  • Vehicle-specific, hand-assembled damping valves manage tire contact, steering response, and body movement
  • Triple-lip fluid seal helps reduce oil and gas leakage
  • Strong strut body and bracket construction helps minimize flex and maintain alignment
  • Dust cover included for added protection
  • Part number: 344380

Product Details

The KYB Excel-G line is KYB’s OE replacement series, built on the same assembly lines and with the same quality components used for original equipment supply. This shock absorber is calibrated to return the vehicle to its original designed performance rather than change ride characteristics. For drivers searching for a front shock absorber for a 1999-2007 Chevrolet Silverado 1500 or 1999-2007 GMC Sierra 1500, KYB 344380 provides a direct-fit suspension service option for the applications listed.

This part cross-references Monroe Shocks & Struts (e.g., 37149) for the same application.

What It Helps Address

  • Excessive front-end bounce after bumps
  • Loose or delayed steering response
  • Reduced body control during lane changes
  • Uneven tire contact caused by worn damping
  • Suspension noise or instability from worn shock performance
