About this gearbox mount bush kit
The SuperPro SPF3863K gearbox 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. The low-compliance polyurethane controls flex, twist and deflection for a firmer, more connected feel without the harshness of solid mounts.
