KYB Excel-G Front Right Strut for Toyota Sienna

KYB Excel-G 334430 is a front right suspension strut for select Toyota Sienna models. It is built to restore original ride control, steering response, and body stability while maintaining OE-style performance.

• OE-style replacement for Asian mini-vans, including Toyota Sienna applications
• Nitrogen gas-charged, twin-tube design for consistent damping
• Triple-lip fluid seal helps reduce oil and gas leakage
• Vehicle-specific, hand-assembled damping valves manage tire contact, steering response, and body movement
• Strong strut body and bracket design helps minimize flex and maintain alignment
• Made in the USA
• Electronic safety systems rely on suspension performance that matches the vehicle manufacturer’s design

Product Details

The KYB Excel-G product line is engineered as an Original Equipment for the Aftermarket solution, using OE-quality components and KYB assembly-line processes. Part number 334430 is calibrated to restore the designed handling characteristics of the Toyota Sienna rather than alter them, making it a practical choice for drivers replacing a worn front right strut on 2004-2006 Toyota Sienna and 2005-2006 Toyota Sienna 7-passenger seating applications. This part cross-references Monroe Shocks & Struts 72236 for the same application.

What It Helps Address

• Excessive bouncing or unsettled ride quality
• Reduced steering response during lane changes
• Body roll or instability in turns
• Uneven tire contact caused by worn damping control
• Noise and vibration from aged suspension components
