- Rubber part at top and bottom of coil spring
- Helps support and protect coil spring
- Replace when worn or not working correctly
The Coil Spring Insulator (Rear) is a basic but critical component of your INFINITI’s suspension system. This part is made with rubber and is located at the top and bottom of your coil springs. These springs help support the weight of your vehicle, keep it at a level height, and absorb road shock. Consequently, the Coil Spring Insulator (Rear) helps guard and support the coil spring. The insulator also helps suppress the motion of your coil spring contracting and expanding, which can create a more comfortable ride.
The Coil Spring Insulator (Rear) is designed to sustain the intensity of its job. However, the rubber can break down and deteriorate over time. This is especially true in climates with extreme temperature fluctuation. After a certain amount of wear and tear, your Coil Spring Insulator (Rear) might break or stop working well. Signs you need to replace your INFINITI Coil Spring Insulator (Rear) include your vehicle bottoming out, grinding sounds when you turn, and loud road noise.
A worn Coil Spring Insulator (Rear) may not immediately harm your INFINITI, but you should still replace it in a timely manner. If you wait too long, you might damage other parts of your vehicle, such as your brakes, tires, coil springs, tie rods, and struts. Unless your coil spring is also worn, you can probably make out with only replacing the insulator. Like the springs, you want to replace your Coil Spring Insulator (Rear) in pairs to help keep your vehicle balanced. If you don't have automotive experience, you should consider bringing your INFINITI into an authorized service center to have the replacement done by professionals.
Your INFINITI Coil Spring Insulator (Rear) is vital to your suspension system, and you want to be sure you have a replacement that's made for your vehicle. Ordering genuine OEM parts is an easy way to find the right fit.
The Coil Spring Insulator (Rear), part 550367S000, is compatible with INFINITI Armada 2004-2021. See the What This Fits tab for more fitment information.
