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

Part Number: RS55117

Summary: The Rancho RS5000X series utilizes a patented progressive engagement valving system to bridge the gap between street comfort and off-road durability. Specifically configured for a 4-inch lift, these gas-pressurized shocks feature a cross-tuned twin-tube design that minimizes aeration and shock fade during rugged use. This complete set provides the necessary damping control to manage the increased center of gravity and larger tire masses associated with lifted Ford F-150 applications.

Features

• Progressive Engagement Valving: Custom-tuned compression and rebound circuits provide a smooth transition between low and high-speed impacts to ensure consistent ride quality on varied terrain.
• Gas Pressurization: High-pressure nitrogen charge provides a reduction in oil foaming and aeration to ensure fade-free performance in demanding environments.
• Twin-Tube Body: A 2.25-inch heavy-duty reserve tube provides increased fluid capacity and dent resistance to ensure long-term reliability in off-road conditions.
• Nitro-Carburized Piston Rod: A 16mm hardened steel rod provides superior corrosion resistance and structural integrity to ensure a long service life.

Frequently Asked Questions

Will these shocks lift my Ford F-150?
No, these shocks do not create lift. They are specifically valved and length-matched to work with vehicles that already have a 4-inch suspension lift installed.

What is the benefit of the twin-tube design?
The twin-tube design features an outer reserve tube that protects the inner working cylinder from rock chips or dents, making it an extremely durable choice for off-road use.

Are the protective boots included?
Yes, this set includes Rancho’s signature red dust boots to protect the piston rods from debris and contaminants.
