Product Details

KYB Excel-G is KYB’s Original Equipment for the Aftermarket line, built on the same OE assembly lines and with OE-quality components used in new vehicle production. This suspension strut is calibrated to restore the vehicle’s original performance rather than change it, making it a practical choice for a Toyota Prius front right strut replacement or a Toyota Prius Plug-In front right suspension strut replacement. Part number 339242 is engineered for consistent damping and predictable road feel in everyday driving.

Compatible With 2010-2015 Toyota Prius, front right, and 2012-2015 Toyota Prius Plug-In, front right. This part cross-references Monroe Shocks & Struts 72688 for the same application.

What It Helps Address

• Excessive bounce or float after bumps
• Reduced steering response during lane changes
• Uneven tire contact caused by worn damping
• Body movement that feels loose or uncontrolled
• Suspension performance that no longer matches factory behavior

Installation Notes

Install according to the manufacturer’s instructions and replace the suspension strut and coil spring assembly as specified for the vehicle. Verify the upper mount thread size is 14x1.50 and confirm all dimensions match the original unit before installation. For added protection, KYB recommends a strut boot, part number SB112, to help shield the strut from dirt, debris, and road salt.

Quality Assurance

KYB is a major OE supplier, and the Excel-G line is produced with OE-quality components and OE-style calibration to restore original suspension behavior. The design includes a triple-lip fluid seal and a rigid strut body and bracket structure to support consistent operation in demanding road conditions.
