The Coil Spring Insulator (Rear) is a basic but essential component of your INFINITI’s suspension system. This part is composed of rubber and is located at the top and bottom of your coil springs. These springs help keep your vehicle at a level height, support its weight, and absorb road shock. In turn, the Coil Spring Insulator (Rear) helps guard and support the coil spring. The insulator also helps dampen the movement of your coil spring contracting and expanding, which can create a steadier ride.
The Coil Spring Insulator (Rear) is designed to withstand the strain of its job. Still, the rubber might break down and deteriorate over time. This is particularly true in climates where temperature fluctuation is common. After a certain amount of wear, your Coil Spring Insulator (Rear) may stop working well or break altogether. Signs your INFINITI Coil Spring Insulator (Rear) needs replacement include your vehicle bottoming out, loud road noise, and grinding sounds when you turn.
A worn Coil Spring Insulator (Rear) might not cause immediate harm to your INFINITI but you still want to replace it quickly. When you wait to replace it, you might damage other parts of your vehicle, such as your brakes, tires, coil springs, tie rods, and struts. Unless your coil spring also appears worn or damaged, you can likely get by with only replacing the insulator. Similar to the springs, you want to replace your Coil Spring Insulator (Rear) in pairs to help keep your vehicle balanced. If you aren’t experienced working with cars, 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. Shopping OEM parts is an easy way to find the right fit.
The Coil Spring Insulator (Rear), part 55050AL500, is compatible with INFINITI 350Z 2003-2009. Find more information under the What This Fits tab.
