KYB Excel-G Front Left Strut

The KYB Excel-G 3340264 is a front left suspension strut built to restore original ride control, stability, stopping response, lane-change feel, and handling. It is a nitrogen gas-charged, twin-tube design made on KYB OE assembly lines with OE-quality components.

Compatible with Lexus RX350, RX350L, RX450h, and RX450hL applications, this Excel-G strut is a direct-fit OE-style replacement for drivers who want factory-correct suspension performance. The KYB Excel-G line is calibrated to return the vehicle to its designed ride characteristics rather than alter them.
