Product Details

KYB Excel-G is part of KYB’s OE replacement line, focused on returning factory ride characteristics rather than altering them. For the 2009-2012 Hyundai Elantra rear suspension, this shock absorber uses hand-assembled damping valves and OE-quality construction to support consistent control over body motion and road input. The design is intended to preserve the vehicle’s original handling balance and support proper operation of systems that depend on suspension geometry and tire contact.

This part cross-references Monroe Shocks & Struts (e.g., 172286) for the same application.

What It Helps Address

• Excessive bouncing after bumps
• Loose or unstable rear suspension feel
• Reduced braking stability
• Poor lane-change response
• Uneven tire contact caused by worn damping

Installation Notes

Fits 2009-2012 Hyundai Elantra, rear. Additional components may be required for the application. KYB recommends replacing shock mount components, part number SM5669, to reduce noise and vibration. A KYB strut boot, part number SB102, can help protect the new shock from dirt, debris, and salt.

Quality Assurance

KYB manufactures Excel-G on the same OE assembly lines used for global original equipment products and calibrates it to restore designed performance. Part number 349084 is built with OE-quality components and is classified by KYB as an Original Equipment for the Aftermarket replacement.
