SuperPro 2004 Pontiac GTO Base Rear 6mm Lower Spring Isolator

When you're working on the suspension, especially if you're replacing springs or dealing with noise, a new spring isolator can make a big difference. This 6mm lower spring isolator from SuperPro is designed to fit a range of vehicles, including popular models like the BMW 3-Series and the Pontiac GTO. It sits between the coil spring and the suspension component, helping to absorb road noise and vibrations, and ensuring the spring sits correctly.

SuperPro makes these isolators from a special polyurethane compound that's tougher and more durable than standard rubber. This material holds up better against extreme temperatures, oils, and moisture, so it lasts longer. Because it's a well-built polyurethane, it also helps to reduce unwanted noise and vibration from the suspension, contributing to a quieter ride and improved handling feel. They're designed and manufactured in Australia, drawing on over 40 years of experience in suspension components.
