Made from premium silicone rubber, these bushings deliver superior vibration isolation and outlast OEM foam or rubber mounts that crack or deteriorate. Each kit includes corrosion-resistant steel cups and bolts for long-lasting durability. Unlike hard urethane mounts that squeak, S&B’s silicone body mounts provide a smooth, stock-like ride that lasts the lifetime of your truck. Designed with a precise boss feature that keys into the frame tab, these mounts ensure an OEM fit and finish.
