KYB SM5550 Coil Spring Insulator - Front Lower

KYB Mount Components Coil Spring Insulator SM5550

KYB SM5550 is a coil spring insulator built to replace worn vibration isolators that can create noise and harshness in the suspension. It is a direct-fit Mount Components part for front lower applications on select Chevrolet Equinox and Pontiac Torrent models.

Key Features

• High-quality replacement spring insulator for suspension service
• Helps reduce squeaks, rattles, and vibration noise from aged insulators
• Built to match or exceed original equipment design and quality
• OE-style fitment for front lower suspension applications
• KYB Mount Components SM5550 for targeted application coverage

Product Details

As part of KYB’s Mount Components line, the SM5550 spring insulator is engineered for application-specific fit and consistent suspension performance. KYB focuses on replacement components that address the noise and vibration caused by hardened or deteriorated insulators, helping restore quieter operation in the front lower suspension. This part cross-references General Motors 15207826 and 15780302 for the same application. Compatible with 2005-2006 Chevrolet Equinox, front lower, and 2006 Pontiac Torrent, front lower. The KYB SM5550 is a practical choice when servicing suspension noise concerns on these vehicles.

Common Issues This Part Addresses

• Squeaks from worn coil spring contact points
• Rattles caused by hardened suspension insulators
• Vibration noise transmitted through the front lower spring seat area
• Loss of OE-like isolation in the suspension assembly
• Noise complaints during bumps, turns, or road irregularities

Installation Notes and Tips

Inspect the surrounding spring seat, mounting surfaces, and related suspension hardware before installation. Replace the insulator when the original part shows cracking, hardening, deformation, or visible wear. Confirm front lower placement and vehicle application before service. Professional suspension service procedures are recommended because coil spring components are under load.

Quality Assurance

KYB designs Mount Components replacement parts to meet application-specific OE-style requirements, with construction intended to match or exceed original equipment standards for fit and function.
