Quiet a clunking, vibrating front strut and restore proper isolation with the KYB strut mount kit SM5723, a front suspension strut mount kit that drops in as a direct-fit replacement for the 2006 Lexus GS300, 2006-2007 Lexus GS430, 2007-2011 Lexus GS350, 2007-2011 Lexus GS450H and 2008-2011 Lexus GS460. Each kit supplies the strut mount, spring insulator, boot and bumper to renew the top mounting point of the front strut assembly.
KYB strut mounts are designed to replace old, hardened isolators that transmit road noise and vibration into the cabin, cushioning impacts from road bumps to help reduce the jarring, noise and harshness that worn mounts pass through. The front bearing plate serves as the steering pivot and helps support vehicle weight, so it plays a key role in steering feel and wheel alignment.
If a failed or hardened front strut mount is the source of your noise or vibration, this kit replaces it. Sold as a mount kit for one strut; replace both sides together for balanced ride quality.
