Rancho RS5000X 4.5″ Rear Lift Shocks for 2015-2018 Ford F-150 2WD

Part Number: RS55287

Summary: The Rancho RS5000X series leverages a cross-tuned twin-tube design to provide a significant upgrade in ride quality for lifted Ford F-150 applications. Engineered specifically for vehicles with 4.5 inches of rear lift, these shocks utilize a unique valving system that minimizes harshness during initial impacts. This creates a smooth, durable dampening solution that excels in both daily commuting and rugged off-road environments.

Features

• Progressive Engagement Valving: Custom-tuned compression and rebound circuits provide increased control during high-velocity movements to ensure consistent stability on uneven terrain.
• Gas Pressurized Design: Low-pressure nitrogen charge provides a reduction in oil foaming and aeration to ensure fade-free performance during extended use.
• 16mm Nitro-Carburized Rod: The heavy-duty hardened piston rod provides superior scuff resistance and structural integrity to ensure long-term seal protection.
• Twin-Tube Body: A 2.25-inch reserve tube provides increased oil capacity and dent resistance to ensure the internal piston remains functional even if the outer shell is damaged.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are extended-length dampers designed to work with a vehicle that already has 4.5 inches of rear lift installed.

What is the benefit of the twin-tube design?
The twin-tube design is highly durable for off-roading; if the outer body is dented by a rock, the inner cylinder is protected, allowing the shock to continue functioning.

Does this include all hardware for installation?
Yes, this pair includes the necessary bushings and protective boots required for a standard bolt-on installation to the OE-style mounts.
