Product Details

KYB Excel-G is built on the same OE assembly lines KYB uses for original equipment supply, with OE-quality components and damping calibration focused on restoring factory performance. For Buick LaCrosse front suspension service, this strut supports consistent ride control, lane-change responsiveness, and braking stability while keeping the vehicle’s suspension behavior close to original design. The Excel-G line is positioned as an Original Equipment for the Aftermarket solution, making it a practical choice for drivers and technicians who want OE-style replacement performance. This part number, 3340055, is also referenced for the same application as Monroe Shocks & Struts 72515.

Common Issues This Strut Addresses

• Excessive bouncing or poor damping over bumps
• Loose steering feel or delayed response during lane changes
• Nose dive, body roll, or unstable braking behavior
• Uneven tire contact caused by worn suspension control
• Noise or fluid loss associated with a worn strut assembly

Installation Notes and Tips

Fits 2014-2016 Buick LaCrosse, front right, except electronic suspension. Verify the upper mount thread size is 14x1.50 and confirm the compressed length of 14.33 in., extended length of 19.88 in., and stroke length of 5.55 in. before installation. Because suspension geometry affects alignment and tire wear, a professional alignment is recommended after replacement. Confirm the vehicle’s suspension configuration matches the listed application before ordering.
