Product Details

KYB Excel-G part number 339231 is engineered as an Original Equipment for the Aftermarket replacement for the front left suspension position. It uses OE-quality components and is assembled on KYB OE production lines to match the original damping characteristics of the vehicle rather than changing them. This makes it a practical choice for a Toyota Highlander front left strut replacement when the goal is to restore factory-like control, lane-change response, and overall suspension behavior. This part cross-references Monroe Shocks & Struts 72484 for the same application.

Common Problems This Strut Addresses

• Excessive bounce or reduced damping at the front left corner
• Loose steering feel or delayed lane-change response
• Uneven tire contact caused by worn suspension control
• Brake dive and body motion during stops and turns
• Suspension noise or fluid leakage from a worn strut assembly

Installation Notes and Tips

Fits 2010 Toyota Highlander, front left, and fits 2008-2009 Toyota Highlander, front left. For 2008-2009 applications, replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. Verify the upper mount thread size is 14x1.50 and confirm all suspension components are inspected before installation. After replacement, a wheel alignment is recommended to restore proper suspension geometry.

Quality Assurance

KYB is a major OE supplier, and the Excel-G line is built to restore original suspension performance using OE-quality components and OE-line manufacturing standards. The reinforced strut body and bracket design is intended to minimize flex and help maintain correct alignment in service.
