Part Number: RS55838

Summary: The Rancho RS5000X series provides a significant upgrade for Ford F-150 owners running a 4.5-inch lift, balancing rugged off-road durability with refined street manners. Utilizing a sophisticated gas-pressurized twin-tube design, these shocks are engineered to minimize fluid aeration and shock fade during consistent cycling. This specific configuration is optimized for the 2015-2018 Ford F-150 2WD, ensuring the suspension maintains controlled damping and a smooth ride quality even with increased ride height.

Features

• Progressive Engagement Valving: Custom-tuned compression and rebound circuits provide a smoother transition between damping forces to ensure maximum comfort on paved surfaces.
• Gas-Pressurized Twin-Tube Design: High-pressure nitrogen gas charge reduces oil foaming and cavitation to provide consistent performance during high-frequency cycling.
• 16mm Nitro-Carburized Rod: The heavy-duty hardened piston rod provides increased structural rigidity and corrosion resistance to ensure a long service life in harsh environments.
• Self-Lubricating Seal: A specialized wiper seal retains internal oil and gas pressure while excluding contaminants to ensure reliable performance in muddy or dusty conditions.

Frequently Asked Questions

Will these shocks lift my Ford F-150 by 4.5 inches?
No, these shocks do not create lift. They are specifically valved and extended to accommodate a 4.5-inch lift kit already installed on your vehicle.

Is this a complete set for the front and rear?
Yes, this SKU includes all four shocks required to outfit the front and rear of your 2015-2018 Ford F-150 2WD.

Does the twin-tube design offer any benefits over monotube shocks?
The twin-tube design is highly durable; the outer tube can take a dent from a rock or debris without affecting the movement of the inner piston, making it ideal for daily driving and moderate trail use.
