Detailed Description

KYB 339177 is engineered for drivers who want suspension performance that matches the vehicle’s original design rather than changing it. The Excel-G line is built to restore ride control, lane-change responsiveness, stopping stability, and handling balance on the Toyota Avalon. This front right strut is designed for 2005 Toyota Avalon and 2006 Toyota Avalon applications listed below, including the 2006 Avalon built to 1/2006.

This part cross-references Monroe Shocks & Struts 72205 for the same application. The KYB Excel-G 339177 also aligns with Toyota OE reference 4851009G60.

What It Helps Address

• Excessive front-end bounce or float
• Reduced steering precision during lane changes
• Uneven tire contact caused by worn damping control
• Body movement that feels loose over bumps or turns
• Suspension performance loss from leaking or fatigued strut components
