Made from premium silicone rubber, these bushings provide superior vibration isolation and won’t crack or deteriorate like OEM foam or rubber mounts. Each set includes corrosion-resistant coated steel cups and bolts for long-lasting durability. Unlike urethane mounts that are hard and prone to squeaking, S&B’s silicone body mounts deliver a smooth, stock-like ride that will last the lifetime of your truck. The cap bushings feature a precise boss design that keys into the frame tab, ensuring an exact OEM fit and finish.
