About this differential centre support bush kit
The SuperPro SPF3404-80K rear differential centre support 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.
Note - Heavy Duty Kit - can cause NVH
