Upgrade your shocks in your Ford Superduty with the Carli Suspension Signature Shocks. These are the same shocks that are used in various suspension kits from Carli. These Signature Series Shocks are longer to accommodate the extended travel. When designing the shocks, Zinc plating, Clear Coat for corrosion resistance and quality bushings were a must; finished off with boots to protect the shafts, their quality is as unbeatable as their ride quality at this price point.
