KYB 340039 Suspension Strut - Front Left

KYB Excel-G Front Left Suspension Strut

KYB Excel-G 340039 is a front left suspension strut built to restore original ride control, stability, and steering response. It is a direct OE-style replacement for select Ford Fusion, Lincoln MKZ, and Mercury Milan applications, with vehicle-specific damping calibrated for factory-like handling.

The Excel-G line is KYB’s OE replacement series, produced on KYB assembly lines using OE-quality components and calibration focused on restoring designed performance rather than changing it. This part number 340039 is a nitrogen gas-charged, twin-tube strut with an internal rebound spring and a triple-lip fluid seal for leak resistance.

Detailed Description

KYB Excel-G 340039 is engineered for drivers replacing a worn front left suspension strut on a 2010-2012 Ford Fusion, 2010-2012 Lincoln MKZ, or 2010-2011 Mercury Milan. With a compressed length of 13.97 inches, extended length of 17.78 inches, and 3.81 inches of stroke, this strut is built around the original suspension geometry for proper ride height and suspension travel. The Excel-G product line is designed to restore factory ride control and help keep electronic safety systems operating as the vehicle manufacturer intended by maintaining suspension, brake, and tire behavior within OE parameters.

This part cross-references Monroe Shocks & Struts 72596 for the same application.

Common Issues This Strut Can Address

• Excessive bouncing or poor damping after the original strut wears out
• Loose steering feel or delayed lane-change response
• Nose dive, body roll, or unstable braking behavior
• Uneven tire contact caused by reduced suspension control
• Noise or vibration related to a worn front left strut assembly

Installation Notes and Tips

Install on the front left position only for the listed Ford Fusion, Lincoln MKZ, and Mercury Milan applications. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. KYB recommends new strut mounts, part number SM5540, to reduce noise and vibration, and a KYB strut boot, part number SB101, to help protect the strut from dirt, debris, and salt.
