Product Details

The KYB Excel-G line is KYB’s OEA-style replacement series, built on the same OE assembly lines and using OE-quality components to return suspension performance to factory-designed behavior rather than changing it. Part number 339282 is engineered for front left use and is sized with a 16.25-inch compressed length, 22.44-inch extended length, and 6.19-inch stroke length. The upper mount type is 14X1.50. This part cross-references Monroe Shocks & Struts 72766 for the same application.

Fits 2010-2015 Lexus RX350, front left. Fits 2010-2015 Lexus RX450h, front left. Fits 2011-2013 Toyota Highlander, front left. Fits 2010 Toyota Highlander, front left.

Common Problems This Strut Can Address

• Excessive bouncing or poor damping over bumps
• Loose steering feel or delayed lane-change response
• Body roll, nose dive, or unstable braking behavior
• Uneven tire contact caused by worn suspension control
• Suspension noise or fluid leakage from a worn strut assembly

Installation Notes and Tips

Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions where specified for Toyota Highlander applications. Verify front left positioning, confirm the 14X1.50 upper mount specification, and inspect related suspension components before installation. Because suspension geometry affects alignment, a professional wheel alignment is recommended after replacement.

Quality Assurance

KYB is a major OE supplier of shocks and struts, and Excel-G is produced to restore original suspension performance using OE-quality components and calibration. The design includes a triple-lip fluid seal, internal rebound spring, and a rigid strut body and bracket structure to support consistent operation in daily driving conditions.
