Product Details

KYB Excel-G struts are built on the same OE assembly lines used for original equipment supply and are calibrated to return the vehicle to its intended ride characteristics rather than change them. For the 2004-2007 Toyota Highlander rear left, 2004-2006 Lexus RX330 rear left, and 2007 Lexus RX350 rear left, part number 334395 supports consistent damping, stable lane-change response, and proper suspension control. The design also helps electronic safety systems operate as the vehicle manufacturer intended by keeping suspension behavior aligned with factory specifications.

Measured specifications include 15.4 in compressed length, 22.81 in extended length, and 7.41 in stroke length. Upper mount type is 14X1.50. Dust cover, internal rebound spring, and B-stop are not included in the listed attributes.

What This Strut Helps Address

• Excessive bouncing or float after bumps
• Reduced rear suspension control during cornering or lane changes
• Uneven tire contact caused by worn damping
• Noise or vibration from aged strut components
• Loss of factory ride feel on Lexus RX330, Lexus RX350, or Toyota Highlander applications

Installation Notes and Tips

For the 2004-2007 Toyota Highlander rear left application, replace the suspension strut and coil spring assembly according to the 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. Verify rear-left fitment and suspension configuration before installation, especially on vehicles listed without air suspension.

Quality Assurance

KYB is a major OE supplier, and Excel-G is classified as an Original Equipment for the Aftermarket replacement line. The 334395 is built to OE-quality standards and calibrated for factory-style performance on the listed Lexus and Toyota applications.
