KYB SM5558 Suspension Coil Spring Seat - Rear Lower

KYB SM5558 Rear Lower Spring Seat

KYB SM5558 is a suspension coil spring seat for rear lower applications on select Volkswagen models. It is built to replace worn vibration insulators that can create noise and reduce suspension refinement in the Volkswagen Jetta, Golf, and Corrado.

As part of KYB Mount Components, this spring seat follows an OE-quality replacement approach for application-specific fitment. The KYB SM5558 is designed to restore proper spring support while helping reduce unwanted vibration transfer at the suspension mount.

Key Features

• OE-quality replacement spring seat for rear lower suspension use
• Reduces squeaks, rattles, and vibration-related noise
• Built to match or exceed original equipment design and quality
• Application-specific fitment for select Volkswagen rear suspension setups
• Part number SM5558 for easy identification and ordering

Detailed Description

KYB Mount Components are engineered for drivers who need a direct replacement for worn suspension isolators and spring seats. The SM5558 helps maintain correct spring positioning and supports quieter operation by replacing hardened or deteriorated components that can transmit noise through the chassis. For Volkswagen Jetta rear lower suspension service, Volkswagen Golf rear lower suspension repair, and Volkswagen Corrado rear lower suspension maintenance, this part provides a focused OE-style solution.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. Use KYB SM5558 when servicing rear lower spring seat wear on compatible Volkswagen suspension assemblies.
