KYB SM5723 front strut mount kit for the 2007-2011 Lexus GS350 and other vehicles replaces old, hardened vibration insulators that carry noise into the vehicle. The front bearing plate acts as a steering pivot and supports vehicle weight.
Hardened rubber can show up as extra noise and vibration over bumps, and a worn bearing plate as steering that feels less smooth. Before you replace the mount, rule out the strut, the tires and other steering and suspension parts, since they can also produce noise, vibration or loose steering.
This KYB strut mount kit is listed for a wide range of Lexus models, led by the 2007-2011 Lexus GS350, the 2007-2011 Lexus GS450h and the 2008-2011 Lexus GS460. Replace the front mounts as a pair: this listing is one kit, and the front axle takes two. If your Lexus is not named here, look up its year and model in the "Vehicles it fits" section.
A strut mount, spring insulator, boot and bumper.
