Excel-G OE Replacement Line

KYB Excel-G is the brand’s OE replacement line for drivers who want the suspension to perform as the vehicle manufacturer originally intended. This strut is built on KYB OE assembly lines using OE-quality components and is classified as an Original Equipment for the Aftermarket replacement. For Scion xB owners, the KYB Excel-G 339204 focuses on restoring ride control rather than changing the vehicle’s handling character.

What This Strut Helps Address

• Excessive bouncing or float after bumps
• Loose steering feel during lane changes
• Reduced body control in turns and braking
• Uneven tire contact caused by worn suspension damping
• Noise or fluid loss associated with a worn strut assembly

Installation Notes

Fits 2008-2015 Scion xB, front right. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. Verify position, mounting dimensions, and upper mount thread specification before installation. This part cross-references Monroe Shocks & Struts (e.g., 72670) for the same application.

Quality Assurance

KYB supplies shocks and struts to new vehicle manufacturers and builds the Excel-G line to OE standards on the same production lines used for original-equipment components. The 339204 uses a twin-tube, gas-charged design with sealing and damping features intended to maintain consistent control and alignment performance.
