Summary: The Rancho RS5000X series is engineered to provide a significant upgrade in ride quality and durability for your heavy-duty truck. Featuring a sophisticated twin-tube design with a larger 2.25-inch body, these shocks provide increased fluid capacity to maintain cooler operating temperatures during heavy hauling.
