Product Details

KYB part number 339390 is engineered as an OE-style suspension strut for the front left position on the Honda Civic. The Excel-G line is calibrated to restore the vehicle’s original suspension behavior rather than alter it, making it a solid choice when the goal is to return factory ride control and handling balance. This part cross-references Monroe Shocks & Struts 72928 for the same application.

What It Helps Address

• Excessive front-end bounce or rebound
• Loose or delayed steering response
• Reduced stability during lane changes and braking
• Uneven tire contact caused by worn damping control
• Suspension noise or handling changes from a worn strut assembly
