KYB SM5486 Coil Spring Insulator

KYB SM5486 is a front upper coil spring insulator for select Honda, Acura, and Isuzu applications. It is built to replace hardened or worn spring seat components that can transmit vibration and noise into the suspension.

For drivers searching for a front upper coil spring insulator for 1990-2001 Honda Accord, Prelude, Odyssey, Acura CL, Acura TL, or Isuzu Oasis, this KYB Mount Components part is made to restore quieter suspension operation and OE-style fitment.

Key Features

• OE-quality replacement spring insulator for suspension service
• Helps reduce squeaks, rattles, and vibration noise from worn insulators
• Built with design and quality that matches or exceeds original equipment
• Part of KYB Mount Components for suspension mounting applications
• Part number SM5486 for easy identification and ordering

Detailed Description

KYB Mount Components focuses on replacement spring seats and insulators that address noise and vibration caused by aged rubber components. SM5486 is engineered for front upper use and supports proper suspension performance by replacing deteriorated insulators with an OE-style component. This part cross-references Monroe Shocks & Struts (e.g., 905920) for the same application.

Compatible With 1990-1997 Honda Accord, front upper; 1992-2001 Honda Prelude, front upper; 1995-1998 Honda Odyssey, front upper; 1995-1998 Acura TL, front upper; 1996-1999 Isuzu Oasis, front upper; and 1997-1999 Acura CL, front upper. If you are servicing a Honda Accord front upper spring insulator or replacing a worn KYB SM5486 on a Prelude or Odyssey, this component supports a direct-fit repair approach.

What It Helps Fix

• Squeaks from hardened suspension insulators
• Rattles caused by worn spring seat material
• Vibration noise transferred through the front suspension
• Loss of quiet operation from aged upper spring mounting parts
• Fitment issues when replacing a damaged OE-style insulator

Installation Notes and Tips

Install SM5486 at the front upper spring location only on the listed vehicles. Inspect the surrounding spring seat, mount components, and related suspension hardware for wear before reassembly. Because spring and strut assemblies are under load, use proper suspension tools and follow the vehicle service procedure during installation.

Quality Assurance

KYB designs Mount Components as OE-quality replacement parts for specific applications, with a focus on fit, noise control, and suspension performance. SM5486 is built to the same general standards expected from KYB replacement suspension components.
