Rancho RS5000X 4″ Rear Lift Shocks for 1981-1986 Ford F-250 4WD

Part Number: RS55112

Summary: The Rancho RS5000X series utilizes a cross-tuned twin-tube gas pressurized design to enhance the ride quality of your lifted Ford F-250. Engineered to handle the increased demands of a 4-inch rear lift, these shocks balance rugged off-road durability with refined street manners. By minimizing aeration and foaming, the RS5000X ensures consistent damping performance during daily hauling or weekend trail use.

Features

• Progressive Engagement Valving: Custom-tuned compression and rebound circuits provide a smoother ride over small bumps to ensure comfort on paved surfaces.
• Gas Pressurized Twin-Tube: High-pressure nitrogen gas charge provides a consistent oil column to ensure reduced shock fade during sustained cycling.
• 16mm Nitro-Carburized Rod: The heavy-duty hardened piston rod provides superior corrosion resistance to ensure long-term seal integrity in harsh environments.
• Self-Lubricating Seal: A specialized PTFE-coated seal provides reduced friction and heat buildup to ensure a longer service life.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically lengthened and valved to accommodate a Ford F-250 that has already been equipped with a 4-inch rear lift system.

What is the benefit of the twin-tube design?
The twin-tube design is highly durable for off-roading; if the outer tube is dented by a rock or debris, the inner working tube remains unaffected, allowing the shock to continue functioning.

Do these come with the red boots shown?
Yes, this pair includes Rancho’s signature red protective boots to shield the piston rod from dirt, salt, and debris.
