What is the purpose of a spring isolator?

A spring isolator sits between the coil spring and the strut mount. Its main job is to absorb vibrations and prevent metal-on-metal contact, which helps reduce noise and improve ride comfort.

Do I need to replace these when I replace my struts?

It's highly recommended to inspect and replace your spring isolators when you're doing strut work. If they are old, hardened, or cracked, they won't function properly and can cause noise or vibration.

Are these the same as spring seats?

Yes, spring seats and spring insulators are often used interchangeably. They serve the same function of cushioning the spring and isolating it from the vehicle's chassis.

Product Details

When you're replacing the front struts on your Ford Expedition, it's a good time to check the condition of your spring seats and insulators. Over time, these parts can harden and crack, 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 made to match the original design and quality of your vehicle's factory parts. They work to cushion the spring against the strut mount, absorbing road shock and preventing metal-on-metal contact. Replacing worn insulators is a simple step that can make a notable difference in overall suspension comfort and quietness.
