Rancho RS5000X 4″ Rear Lift Shocks for 1981-1996 Ford F-150 4WD

Part Number: RS55112

Summary: The Rancho RS5000X series leverages a unique gas-pressurized twin-tube design to deliver superior ride quality for lifted applications. Engineered to handle the increased demands of a 4-inch rear lift, these shocks utilize a progressive engagement valving system to minimize harshness during initial impacts. This setup provides the ideal balance of rugged durability for off-road excursions and smooth, controlled damping for daily street driving.

Features

• Progressive Engagement Valving: Custom-tuned internal discs provide a gradual transition between damping stages to ensure a smooth ride over varied terrain.
• Gas Pressurized Twin-Tube: High-pressure nitrogen gas prevents oil aeration and foaming to ensure consistent damping performance under heavy loads.
• 16mm Nitro-Carburized Rod: The heavy-duty piston rod provides increased structural rigidity and scuff resistance to ensure long-term seal integrity.
• Protective Boot Included: A durable poly-vinyl accordion boot protects the shock rod from debris and stone peening to ensure maximum service life.
