About this part
The SuperPro SPF2121-90K front lower control arm inner 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 competition kit, it can add noise, vibration and harshness.
