Factory mounts are constructed of rubber that breaks down over time and exposure to the elements. As they break down, they become less effective at isolating the cab from chassis noise and vibration. In extreme circumstances, worn body mounts can cause the body to shift on the frame and increase body roll. Numerous problems with components that attach to both the body and the chassis, such as mechanical shift linkage, are also indicators of worn body mounts. Daystar Body Mounts are resistant to vehicle fluids and road grime. They outlast factory body mounts and provide more positive attachment to the frame. Precision-engineered to be a direct replacement for factory mounts, they are constructed of a special polyurethane blend that helps insulate the cab while maintaining superior holding power. Daystar body mounts are the perfect upgrade for worn stock mounts and are particularly beneficial in racing applications.
