Especially on higher mileage 7.3L Powerstroke diesel trucks or those subject to harsh environments, the factory rubber body mounts degrade and become hard as rocks. This means that any of the noise and vibration running through your frame is immediately transmitted to the cab, eliminating the benefit of having isolators in the first place. Replace yours with a superior product, silicone!

• These bushings offer great vibration isolation and will not crack or breakdown like the OEM foam or rubber bushings. Also comes with corrosion resistant coated steel cups and bolts.

• Stock body mounts deteriorate over time and cost a fortune. Urethane mounts are hard and squeak. S&B’s Silicone Body Mounts have a smooth stock ride and last the life of your truck.

• The cap bushings have a distinct boss feature on it that matches the slot on the mounting tabs. They are designed to key into the frame tab and give it an OEM fit.
