What is the purpose of a spring isolator?

A spring isolator sits between the coil spring and the strut mount or chassis. Its main job is to prevent metal-on-metal contact and absorb vibrations and noise generated by the spring compressing and expanding.

Why should I replace my spring isolators?

Over time, the rubber or plastic material of spring isolators can harden, crack, or degrade. This wear can lead to increased noise, vibration, and a less comfortable ride, so replacing them with new ones helps restore original performance.

Does this part come with new struts or mounts?

This product is for the KYB Spring Isolator (part number SM5709) only. It does not include the struts, shocks, or strut mounts themselves.

Product Details

When you're replacing the front struts on your 2003-2008 INFINITI FX35, it's the perfect time to swap out those old, hardened spring seats and insulators. Over time, these parts can break down, leading to extra vibration and noise that travels up into the cabin. KYB offers these OE quality replacement spring insulators to help restore a quieter, smoother ride.

These insulators are built to match the original design and quality of your FX35's factory components. By replacing worn-out rubber or plastic parts, you help ensure your suspension is working as intended, absorbing road imperfections without transmitting unnecessary noise. It's a small part that makes a noticeable difference in overall comfort.
