Rancho RS5000X 4″ Lift Shocks for 1999-2004 Ford F-350 4WD

Part Number: RS55264 / RS55261

Summary: The Rancho RS5000X series is engineered to provide a significant upgrade in ride quality and durability for your Ford F-350. Utilizing a sophisticated twin-tube design with a large 2.25-inch body, these shocks offer increased fluid capacity to maintain cooler operating temperatures during heavy-duty use. This set is specifically configured for vehicles with a 4-inch lift, ensuring the piston remains in the optimal stroke zone for both on-road comfort and off-road resilience.

Features

• Progressive Engagement Valving: Custom-tuned compression and rebound circuits provide a smooth transition between damping forces to ensure maximum comfort on varied terrain.
• Gas Pressurized Twin-Tube: High-pressure nitrogen gas charge provides a consistent response and reduces aeration to ensure fade-free performance during towing or hauling.
• Large 2.25-inch Body: An oversized shock body increases oil capacity to provide superior heat dissipation for sustained damping control under heavy loads.
• Protective Boot Included: A durable poly-vinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity against road debris.
