Summary: The Rancho RS5000X series is engineered to provide a significant upgrade in ride quality and durability for your GMC Sierra 2500HD.

• Gas Pressurization: High-pressure nitrogen gas charging provides reduced aeration and foaming to ensure consistent damping performance under heavy loads.
• Enlarged Shock Body: A 2.25-inch twin-tube body provides increased fluid capacity to ensure cooler operating temperatures during towing or hauling.
