Product Details

KYB Mount Components focuses on suspension support parts that address noise and vibration at the spring seat. This coil spring insulator is engineered for applications where the original insulator has hardened, cracked, or compressed over time. In Lexus ES300h, Lexus ES350, Toyota Avalon, and Toyota Camry rear suspension service, the insulator helps maintain proper spring contact and reduces unwanted movement at the mounting point. If you are replacing a worn rear left lower coil spring insulator on a Toyota Camry or Lexus ES350, KYB SM5719 provides an OE-quality service part for the application.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

• Squeaks from worn spring seat material
• Rattles caused by deteriorated suspension insulators
• Vibration noise transferred through the rear suspension
• Noise from hardened or compressed coil spring contact points
• Loss of proper spring isolation at the rear left lower position

Installation Notes

Install SM5719 at the rear left lower spring location only on the listed vehicles. Inspect the surrounding spring seat, perch, and related suspension components for wear before reassembly. Proper alignment of the coil spring and insulator is important to maintain quiet operation and correct seating.

Quality Assurance

KYB designs Mount Components as OE-quality replacement suspension parts for specific applications. SM5719 is built to the same design and quality standards expected for original-equipment-style service on the listed Lexus and Toyota models.
