Description
The Mercedes-Benz Coil Spring Shim / Lower Spring Insulator (Part No. A2123220084) is a genuine OEM suspension component that fits under the front coil spring to provide proper seating, damping and alignment. This small but essential rubber/metal shim prevents metal-to-metal contact, reduces noise and vibration, and helps maintain correct spring preload and ride height.
Manufactured to Mercedes-Benz specifications, the spring shim ensures long service life and proper suspension geometry after repair or spring replacement. Worn or missing shims can cause rattles, uneven ride height, premature spring wear, or abnormal spring movement. Replacing the shim with the correct OEM part restores factory fitment and ride quality.
