KYB Coil Spring Insulator P/N:SM5649
KYB Coil Spring Insulator P/N:SM5649
$17.99

Quiet the ride and cushion your coil spring with the KYB coil spring insulator SM5649, a front lower spring seat insulator that drops in as a direct-fit replacement for the listed applications. It fits many Toyota and Lexus models, among them the 2004-2011 Toyota Camry, 2007-2010 Toyota Sienna and 2004-2012 Toyota Avalon; see the Buyer's Guide tab for the full list. It sits between the coil spring and the front lower spring seat, cushioning that contact point so the spring is isolated from the chassis.

  • Isolates noise and vibration: helps reduce squeaks, rattles and vibration noises that hardened, worn insulators can transmit into the cabin.
  • Application-specific fit: an OE-quality replacement component designed for each listed application.
  • Built to match the original: engineered with design and quality intended to match or exceed the original equipment part.
  • Front lower position: installs at the front lower spring seat on the covered Toyota and Lexus applications.

Over time, factory spring insulators harden and crack, allowing the coil spring to contact metal directly. If a worn or deteriorated insulator is the source of your suspension noise, this KYB unit replaces it and re-establishes that cushion. See the Buyer's Guide tab for engine-level fitment on your specific vehicle.

Where is this insulator located?

It installs at the front lower spring seat on the listed applications. Check the Buyer's Guide tab for engine-level details on your vehicle.

What are signs the spring insulator may need replacing?

Squeaks, rattles or vibration noises from the suspension can appear as the factory insulator hardens or cracks over time and lets the coil spring contact metal directly.
