Product Details

The KYB SM5358 Spring Seat Insulator is an OE-quality replacement component designed to restore proper suspension function by eliminating vibration and noise caused by worn or hardened factory insulators. This precision-engineered insulator sits between the coil spring and the vehicle's spring seat, providing critical cushioning and isolation.

Key Features:

  • Eliminates vibration transfer and road noise from deteriorated original insulators
  • OE-quality construction engineered for specific vehicle applications
  • Restores proper suspension geometry and spring positioning
  • Manufactured to KYB's industry-leading quality standards
  • Direct replacement for worn factory spring seat insulators

Over time, spring seat insulators become compressed, hardened, and cracked due to constant load and exposure to the elements. Replacing worn insulators with this KYB component ensures optimal suspension performance, reduces cabin noise, and prevents metal-to-metal contact that can damage suspension components.

Looks good!

This was the best price I could find. Free shipping. Two day delivery.

Fast shipping and best price on my performance gaskets. Thanks!

Awesome service at great price!

Quick and easy; less than 3 minutes.

Was very pleased with the hubb filter i ordered, product is very well made and i can't wait to put it to use.

Easy enough... we'll see if it arrives.

Fast shipping

They had the lowest price on the web and carried the part I needed. They used amazon. Heck out so it was super easy to place the order and the part shipped right away. Will definitely order from again.

Best price I could find on the web even after paying for shipping! Shipped in a couple of days and great service!

This is a great e-retailer. Best price and fast shipping. I ordered a bike rack. Their price was the lowest I could find, and it was drop shipped from the manufacturer the following day, and arrived in time for me to use it on the weekend. The one criticism I would have is the item description could have been better. From my web research, I knew the model I wanted, but if I was just browsing bike racks on their website, I would have needed more information.

Really great prices with cheap shipping, best I could find. Can't wait to use the bed extender for hauling my kayaks!

Shipping was surprisingly fast price was great. Second time ordering
