KYB SM5525 Coil Spring Insulator - Rear Upper

KYB SM5525 Coil Spring Insulator

KYB SM5525 is a coil spring insulator for the rear upper suspension position on select Honda Accord models. It is built to replace worn vibration insulators that can create noise and reduce suspension refinement.

For drivers searching for a Honda Accord rear upper coil spring insulator, KYB SM5525 provides an OE-style replacement focused on fit, noise control, and suspension performance.

Key Features

• High-quality replacement spring insulator for suspension service
• Reduces squeaks, rattles, and vibration noise from aged insulators
• Built to match or exceed original equipment design and quality
• Fits 1990-1997 Honda Accord, rear upper
• Part number SM5525 for easy identification and ordering

Product Details

KYB’s Mount Components line includes spring seats and insulators engineered for application-specific fitment and consistent suspension operation. SM5525 is made for the rear upper position on 1990-1997 Honda Accord models, where a deteriorated insulator can allow spring noise and unwanted vibration to transfer into the chassis. This part cross-references Monroe Shocks & Struts (e.g., 905974) for the same application.

Use KYB SM5525 when replacing a worn Honda Accord rear upper coil spring insulator and restoring quieter suspension operation. The part number SM5525 is also useful when comparing OE replacement options for this application.

What It Helps Fix

• Squeaks from hardened or cracked spring insulators
• Rattles caused by worn suspension mounting surfaces
• Vibration noise transmitted through the rear suspension
• Loss of OE-style spring seating support
• Noise concerns during cornering or road impact

Installation Notes

Install SM5525 at the rear upper spring location on the listed Honda Accord applications. Inspect the surrounding suspension components, spring seat surfaces, and mounting points before installation, and replace any damaged related parts during service. Verify year, model, and position before ordering to confirm the correct Honda Accord rear upper fitment.

Quality Assurance

KYB positions this Mount Components part as an OE-quality replacement built for application-specific fit and suspension refinement. SM5525 is engineered to address noise and vibration concerns associated with aged spring insulators while maintaining the intended suspension interface for the vehicle.
