What is the main benefit of using a polyurethane spring isolator over a rubber one?

Polyurethane is much more resistant to degradation from heat, oils, and moisture compared to rubber. This means the isolator will last longer and maintain its performance characteristics without cracking or breaking down over time.

Does this spring isolator come with any hardware?

This product is for the spring isolator only. Any necessary hardware for installation would need to be sourced separately, so refer to your vehicle's service manual for specific requirements.

How does this part help with vehicle handling?

By providing a stable and durable interface between the spring and the suspension arm, this isolator helps maintain correct suspension geometry. This can lead to more consistent handling and better steering response.

Product Details

When you're working on the suspension, especially if you're replacing springs or dealing with noise, these lower spring isolators are a small but important part. This specific isolator from SuperPro is 8mm thick and designed to sit between the coil spring and the suspension arm. It's made from SuperPro's own blend of engineering-grade polyurethane, which is a step up from the original rubber parts. Polyurethane is known for being unaffected by extreme temperatures, oils, and moisture, and it won't degrade over time like rubber can. This means you get a quieter ride and better-maintained suspension geometry for longer.

SuperPro has been making bushings and suspension components for over 40 years, and they engineer and manufacture their products in Australia. Their polyurethane formula is refined to handle tough conditions, offering a more durable and reliable solution than stock rubber. Using these isolators can help correct or maintain your steering geometry, leading to improved handling and potentially better tire wear. They're a solid option for anyone looking to refresh their suspension with parts that are built to last.
