KYB 344807 Shock Absorber - Rear

KYB Excel-G Rear Shock for Audi A4

KYB Excel-G part number 344807 is a rear suspension shock absorber built to restore original ride control, stability, and handling on select Audi A4 and Audi A4 Quattro models. It is a recommended OE replacement for drivers who want factory-style damping performance without changing the vehicle’s designed behavior.

The Excel-G line is KYB’s OEA-style replacement range, produced on KYB OE assembly lines with OE-quality components and calibration focused on restoring original performance. For 2005-2009 Audi A4 rear suspension service, 344807 is a direct-fit option for non-sport suspension applications.

Detailed Description

KYB 344807 is engineered for rear suspension replacement on the 2005-2008 Audi A4 and Audi A4 Quattro, plus 2009 Audi A4 and Audi A4 Quattro models without sport suspension. This Excel-G shock absorber is calibrated to return the vehicle to its original ride characteristics, helping preserve braking stability, lane-change response, and overall chassis control. This part cross-references Monroe Shocks & Struts (e.g., 71332) for the same application.

As part of the KYB Excel-G product line, this shock uses OE-style construction and damping control to support the suspension, brakes, and electronic safety systems working as the manufacturer intended. Part number 344807 is a practical choice when replacing a worn rear shock on an Audi A4 or Audi A4 Quattro and maintaining factory-like behavior matters.

What It Helps Address

• Excessive rear bounce or oscillation
• Reduced stability during braking and cornering
• Loose or delayed steering response from worn damping
• Uneven tire contact caused by weak rear shock control
• Body movement that feels uncontrolled over bumps and transitions
