Detailed Description

KYB 334429 is engineered for the rear left position on the Toyota Highlander and is intended to restore the suspension’s original balance rather than change the vehicle’s ride character. The Excel-G platform is designed around OE-style damping, making it a practical choice when the goal is to recover factory handling, lane-change response, and braking stability. This part cross-references Monroe Shocks & Struts (e.g., 71497) for the same application.

With a compressed length of 17.33 inches, extended length of 24.26 inches, and stroke length of 6.93 inches, this strut is built to match the required suspension travel for the listed application. The 14X1.50 upper mount thread specification and R-stop design are part of the OE-style configuration. KYB also notes that electronic safety systems depend on suspension, brakes, and tires working as the manufacturer intended, making correct strut performance important on the Toyota Highlander.

What This Strut Helps Address

• Excessive rear suspension bounce or rebound
• Reduced stability during lane changes and cornering
• Longer stopping distances caused by worn damping
• Uneven tire contact and inconsistent road holding
• Noisy or loose-feeling rear suspension behavior

Installation Notes and Tips

Compatible with 2001-2003 Toyota Highlander rear left applications. The manufacturer notes that the suspension strut and coil spring assembly should be replaced according to the vehicle manufacturer’s instructions. KYB recommends new strut mounts, part number SM5175, to reduce noise and vibration, and a KYB strut boot, part number SB101, to help protect the strut from dirt, debris, and salt.

Quality Assurance

KYB is a major OE supplier to vehicle manufacturers, and the Excel-G line is produced on the same KYB assembly lines using OE-quality components. The design focus is restoring original suspension performance for the Toyota Highlander application covered by part number 334429.
