Cushion the front lower coil springs and keep out metal-to-metal contact with the Mevotech Supreme Coil Spring Insulator MP904945. This front lower insulator drops in as a direct-fit replacement for many vehicles, among them the 1997-2005 Chevrolet Malibu, 1999-2005 Pontiac Grand Am and 1999-2004 Oldsmobile Alero — see the "Vehicles it fits" section for the full list.
Seated between the coil spring and its perch, the insulator pads the contact point to dampen road noise and vibration and to help protect the spring seat from wear caused by direct metal contact.
- 100% natural rubber: all moulded parts use 100% natural rubber to provide durability.
- Front lower position: located at the front lower coil spring seat on the listed applications.
- Direct-fit replacement: designed to install in place of a worn, cracked, or compressed original insulator.
Cracked, flattened, or missing insulators can allow the spring to contact the seat directly, producing creaks, groans, or clunks over bumps. If a worn insulator is the cause, this part replaces it. Sold individually; inspect both sides and replace as needed.

Frequently Asked Questions
What is a coil spring insulator?
It is a rubber pad that seats between the coil spring and its perch, cushioning the contact point to reduce noise and vibration and help prevent direct metal-to-metal contact at the spring seat.
What vehicles does the MP904945 fit?
It fits many vehicles, among them the 1997-2005 Chevrolet Malibu, 1999-2005 Pontiac Grand Am and 1999-2004 Oldsmobile Alero. Check the "Vehicles it fits" section for the full list.
What is this insulator made of?
All moulded parts use 100% natural rubber to provide durability at the coil spring seat.
What position does it install in?
This is a front lower coil spring insulator, located at the front lower spring seat on the listed applications.
How do I know if my insulator needs replacing?
Cracked, flattened, or missing insulators can let the spring contact the seat directly, causing creaks, groans, or clunks over bumps. If a worn insulator is the cause, replacing it can help.
