Product Details

KYB Excel-G is the brand’s OE-style replacement line, built to match original suspension behavior using OE-quality components and calibration. For the Buick Regal, part number 339376 is engineered as a front left suspension strut with a compressed length of 13.93 inches, extended length of 19.44 inches, and stroke length of 5.51 inches. The upper mount type is 14X1.50. This part cross-references Monroe Shocks & Struts 72184 for the same application.

As a KYB Excel-G strut, 339376 is aimed at restoring factory ride control on 2011-2013 Buick Regal models without active suspension and 2014-2017 Buick Regal models without active suspension. It is a practical OE replacement for technicians servicing the front left corner of the suspension system.

What It Helps Address

• Excessive bounce or float in the front suspension
• Reduced steering response during lane changes
• Nose dive under braking
• Uneven tire contact caused by worn damping
• Noise and vibration from a worn front strut assembly

Installation Notes

Fits 2014-2017 Buick Regal, front left. Fits 2011-2013 Buick Regal, front left. For reduced noise and vibration, KYB recommends replacing the strut mount with SM5610. To help protect the new strut from dirt, debris, and salt, KYB recommends a strut boot, part number SB103. Verify suspension configuration before installation; this part is for vehicles without active suspension.

Quality Assurance

KYB supplies shocks and struts to new vehicle manufacturers, and the Excel-G line is produced on the same OE assembly lines using OE-quality components. The design is calibrated to restore original suspension performance for Buick Regal applications while helping maintain proper alignment and electronic safety system operation as intended by the vehicle manufacturer.
