Detailed Product Description

The KYB SM5576 coil spring insulator is a suspension component that fits within the coil spring assembly to cushion and isolate the spring from the vehicle’s chassis. This reduces metal-to-metal contact, which can cause noise and premature wear. Designed for Chrysler and Dodge vehicles including the 300M, Concorde, Intrepid, and LHS, this insulator ensures proper spring seating and helps maintain suspension integrity over time. The part number SM5576 allows for easy identification and compatibility verification.

This coil spring insulator is part of KYB's Mount Components product line, which focuses on providing essential suspension mounting parts that contribute to vehicle stability and ride comfort. The Mount Components line is engineered to meet or exceed OEM specifications, ensuring that each part integrates seamlessly with the vehicle’s suspension system.

Common Applications and Issues Addressed

  • Reduces suspension noise caused by coil spring contact
  • Prevents premature wear of coil springs and mounting points
  • Improves ride quality by cushioning spring movement
  • Maintains proper spring alignment and seating
  • Helps avoid suspension rattles and vibrations

Installation Notes and Tips

  • Ensure vehicle is safely lifted and supported before installation
  • Inspect coil springs and related suspension components for wear
  • Clean mounting surfaces to ensure proper fitment of the insulator
  • Use the part number SM5576 to confirm correct replacement
  • Follow manufacturer torque specifications when reassembling suspension
