About this part
The SuperPro SPF4112-90K rear diff rear mount 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 and more consistent geometry under load. As a track kit, it can add noise, vibration and harshness.
