Detailed Description

This Mevotech stabilizer bar bushing is specified for rear-to-frame use and is sized for the listed Lexus applications. The rubber material helps maintain stabilizer bar positioning at the frame mount, which is important for consistent suspension response and reduced play at the sway bar attachment point.
