• Corrosion-resistant finish for added protection in exposed suspension locations
• Measures 7.65 in. long and 6.5 in. wide
• Front lower coil spring insulator application
• Mevotech MP904945 replacement part
• Cross-references Delphi TC6515 for the same application

Detailed Description

This coil spring insulator is used at the front lower spring seat to separate the coil spring from the suspension perch and help maintain proper interface between components. The corrosion-resistant finish supports long-term service in areas exposed to road splash, moisture, and debris. Mevotech MP904945 is a fitment-based replacement for 1997-2005 Chevrolet Malibu, 1999-2005 Pontiac Grand Am, 1999-2004 Oldsmobile Alero, and 1997-1999 Oldsmobile Cutlass, all in the front lower position. This part also cross-references Delphi TC6515 for the same application.

What It Helps Address

• Noise from worn or deteriorated spring isolators
• Metal-to-metal contact at the front lower spring seat
• Suspension vibration transmitted through the coil spring mount
• Wear at the spring-to-seat contact surface
• Corrosion-related deterioration in the spring interface area

Installation Notes and Tips

• Verify front lower fitment before ordering using the vehicle year, make, and model.
• Inspect the spring seat, perch, and surrounding suspension components for wear before installation.
• Replace the insulator if it is cracked, compressed, or missing material.
• Follow proper spring compression and suspension service procedures during installation.

Quality Assurance

Mevotech suspension components are engineered for service replacement applications, and MP904945 is built with a corrosion-resistant finish to support durability in the front lower suspension environment.
