KYB Suspension Strut Mount P/N:SM5681
KYB SM5205 front strut mount for the 2002-2010 Lexus SC430 and other vehicles cushions road impacts and cuts the vibration that old mounts pass into the car. It replaces old, hardened vibration insulators, and front bearing plates act as steering pivots that support vehicle weight.
A worn suspension strut mount can show up as a clunk over bumps or extra noise when you turn the wheel. Those signs alone do not prove the mount is the problem; a worn strut can make similar noise.
The vehicles it fits include the 2002-2010 Lexus SC430, the 1996-2005 Lexus GS300 and the 2001-2005 Lexus GS430, and it is an OE quality replacement designed for each application. The 2002-2010 Lexus SC430 takes two, so order two and fit them together. If your Lexus is not named here, look up its year and model in the "Vehicles it fits" section.
