Excel-G Product Line Details

KYB Excel-G is KYB’s original-equipment-aftermarket line, built on the same assembly lines and with the same OE-quality components used in KYB factory supply. The goal is not to change the vehicle’s ride character, but to return it to the control, stability, and handling the manufacturer originally calibrated.

Detailed Description

Compatible with 2006 Lexus RX400h rear right, 2007 Lexus RX400h rear right, and 2006-2007 Toyota Highlander rear right, this KYB strut is a direct-fit service part for restoring suspension performance. The 339210 uses a nitrogen gas-charged twin-tube design, a triple-lip fluid seal, and KYB’s in-house damping valve calibration to help maintain consistent tire contact and body control. This part cross-references Toyota 4853049625 for the same application.

What It Helps Address

• Excessive bounce or float from a worn rear strut
• Reduced stability during lane changes and cornering
• Poor tire contact that can affect braking and handling
• Oil seepage or gas loss from aging suspension components
• Alignment concerns caused by flex in worn strut assemblies

Installation Notes and Tips

Fits 2006-2007 Toyota Highlander, rear right; fits 2006-2007 Lexus RX400h, rear right; and fits 2007 Lexus RX400h, rear right. For the 2006-2007 Toyota Highlander and 2006-2007 Lexus RX400h applications, replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. KYB recommends new strut mount SM5491 to reduce noise and vibration, and strut boot SB104 to help protect the strut from dirt, debris, and salt.
