SuperPro 1958 Austin Healey Sprite Base Rear Spring Isolator Set

Made from a durable polyurethane material, these SuperPro rear spring isolators are a smart replacement for your worn-out factory rubber bushings. When the rubber bushings that locate your rear leaf springs start to degrade, they can allow the rear axle to move more than it should. This unwanted movement can lead to a feeling of instability, especially under braking or when carrying a load, and can even cause a phenomenon known as passive steer, where the rear end seems to wander or steer itself. By fitting these SuperPro isolators, you're essentially locking down that rear axle movement, giving you a more stable and predictable feel from the back of your Sprite.

These aren't just simple rubber replacements; SuperPro uses a specially formulated polyurethane that offers a good balance of durability and performance. While OE rubber bushings are designed for standard conditions, these polyurethane isolators are built to handle more demanding situations, whether that's carrying extra gear or just providing a more solid feel on the road. They are designed to fit right into your existing leaf spring setup, making them a straightforward upgrade to improve your vehicle's rear-end stability and handling characteristics.
