KYB SM5433 Coil Spring Insulator - Rear Upper

KYB Rear Upper Coil Spring Insulator SM5433

KYB SM5433 is a rear upper coil spring insulator for select Chrysler, Dodge, and Mitsubishi applications. It is built to replace worn vibration insulators that can create noise and reduce suspension refinement, with OE-style fitment for the listed vehicles.

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
• Part number SM5433 for easy identification and ordering
• Compatible with rear upper mounting locations on the listed applications

Product Details

KYB Mount Components focuses on suspension support parts that restore proper isolation between the spring and its mounting point. This spring seat and insulator is engineered for the rear upper position on select 1995-2005 Chrysler Sebring, 2001-2005 Dodge Stratus, 1995-2005 Mitsubishi Eclipse, 1999-2003 Mitsubishi Galant, and 1995-2000 Dodge Avenger models. For drivers searching for a rear upper coil spring insulator for Chrysler Sebring, Dodge Stratus, or Mitsubishi Eclipse applications, SM5433 provides an OE-quality replacement solution. This part cross-references Monroe Shocks & Struts (e.g., 907993, 909969) for the same application.

What It Helps Address

• Squeaking or rattling from a worn rear upper spring insulator
• Vibration noise transmitted through the suspension
• Degraded spring isolation caused by hardened rubber components
• Loss of original suspension refinement on the rear upper mount
• Need for an OE-style replacement during suspension repair

Installation Notes and Tips

Install SM5433 at the rear upper spring location only on the listed vehicles. Verify year, make, model, and suspension configuration before installation; 1999-2003 Mitsubishi Galant applications are not compatible with adjustable suspensions. Inspect the surrounding spring seat and mounting surfaces for wear before reassembly to help ensure proper fit and noise isolation.

Quality Assurance

KYB spring seats and insulators are built as OE-quality replacement components for specific applications, with design and material choices aimed at restoring suspension isolation and reducing unwanted noise.
