KYB SM5707 Coil Spring Insulator - Front Lower

KYB SM5707 Spring Insulator for Civic and CSX

KYB SM5707 is a coil spring insulator for the front lower suspension position on select Honda Civic and Acura CSX applications. It is built to replace hardened or worn spring seats that can transmit noise and vibration into the chassis.

Key Features

• High-quality replacement spring insulator for suspension service
• Helps reduce squeaks, rattles, and vibration noise from worn insulators
• Built to match or exceed original equipment design and quality
• OE-style fitment for front lower spring seat applications
• Part number SM5707 for easy identification and ordering

Product Details

KYB Mount Components focuses on suspension mounting parts that restore proper isolation between the spring and the vehicle body. This spring seat insulator is engineered for applications where the original insulator has hardened, cracked, or compressed over time. For drivers searching for a Honda Civic front lower coil spring insulator or an Acura CSX suspension insulator replacement, SM5707 provides a direct-fit service part built around the original application requirements. This part number, SM5707, is commonly selected when the goal is to restore quieter suspension operation without changing the vehicle’s factory suspension layout.

What It Helps Fix

• Front suspension squeaks caused by deteriorated spring insulators
• Rattles from metal-to-metal contact at the spring seat
• Excess vibration transferred through worn mounting components
• Noisy ride quality from compressed or hardened insulator material
• Loss of proper spring isolation in the front lower position

Installation Notes and Fitment

• Fits 2007-2015 Honda Civic, Front Lower
• Fits 2006-2015 Honda Civic, Front Lower, Lower Spring Seat Insulator
• Fits 2007-2010 Acura CSX, Front Lower

Installation should follow the vehicle service procedure for front suspension spring components. Inspect the spring seat, adjacent mounting surfaces, and related suspension hardware for wear before reassembly. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Quality Assurance

KYB is known for OE-quality suspension replacement components, and the Mount Components line is built to support factory-style fit and function for the listed applications. The SM5707 is designed for consistent material quality and application-specific fitment in front lower spring seat service.
