About this subframe bush kit
The SuperPro SPF3818K rear subframe bush kit replaces soft factory rubber, which is designed for ride comfort and noise isolation but over time softens, cracks and allows excess movement that dulls handling and can affect alignment. The low-compliance polyurethane controls flex, twist and deflection for sharper steering response, more consistent geometry under load and a more connected, predictable feel without the harshness of solid mounts.
