KYB SM5528 Coil Spring Insulator - Rear Upper

KYB SM5528 Coil Spring Insulator Overview

KYB SM5528 is a rear upper coil spring insulator designed to replace hardened or worn vibration isolators that can create noise and harshness in the suspension. Built for Acura Integra, Honda CR-V, Honda Civic, and Honda Civic del Sol applications, it helps restore quieter operation and more consistent suspension performance.

As part of KYB Mount Components, this spring insulator follows an OE-style replacement approach for application-specific fit and function. If you are servicing a rear upper suspension mount on a 1992-2001 Honda Civic or related fitment, KYB SM5528 provides a direct replacement path for the original insulator.

Key Features

• High-quality replacement spring insulator for rear upper suspension locations
• Helps reduce squeaks, rattles, and vibration noise from aged insulators
• Built to match or exceed original equipment design and quality
• Application-specific fitment for Acura Integra, Honda CR-V, Honda Civic, and Honda Civic del Sol
• Part number SM5528 for easy catalog matching and service lookup

KYB Mount Components Line

KYB Mount Components focuses on suspension mounting parts that address noise and vibration at the source. This product line is aimed at restoring the feel of the original suspension by replacing worn rubber isolation components with OE-quality service parts matched to the vehicle application.

Detailed Description

KYB SM5528 is a coil spring insulator used at the rear upper suspension position to isolate the spring from the body or mount surface. Over time, original insulators can harden, crack, or compress, which often leads to suspension noise and a less refined ride. Replacing the insulator can help return the suspension to quieter, more controlled operation on vehicles such as the Honda Civic, Honda CR-V, and Acura Integra.

This part cross-references Monroe Shocks & Struts 905977 for the same application.

Common Issues This Part May Address

• Squeaking from the rear upper spring area
• Rattling or clunking caused by deteriorated insulators
• Vibration noise transmitted through the suspension
• Loss of isolation from hardened or compressed rubber components
• Noise complaints after suspension service on Honda and Acura rear upper mounts

Installation Notes and Tips

• Verify rear upper fitment before ordering: 1992-2000 Honda Civic, 1993-1997 Honda Civic del Sol, 1994-2001 Acura Integra, and 1997-2001 Honda CR-V.
• Inspect the surrounding spring seat and mount components for wear, cracking, or deformation during service.
• Replace worn isolation parts as a matched repair when the original insulator shows hardening or damage.
• Confirm the rear upper position during installation to avoid mixing it with other suspension mounting locations.

Quality Assurance

KYB designs this replacement insulator to meet application-specific OE expectations for fit, function, and noise control. The SM5528 is built with the design and quality standards associated with KYB suspension mount components.
