Rancho RS5000X 4″ Lift Shocks for 2005-2010 Ford F-350 4WD Single Rear Wheel

Part Number: RS55044 (Set)

Summary: The Rancho RS5000X series provides a significant upgrade for the Ford F-350 Super Duty, utilizing a cross-tuned twin-tube design to enhance both on-road comfort and off-road durability. Engineered specifically for vehicles with a 4-inch lift, these shocks utilize a progressive engagement valving system to minimize harshness during initial impacts. This configuration is ideal for heavy-duty applications, offering the dent-resistant ruggedness of a twin-tube body with the consistent performance of a gas-pressurized shock.

Features

• Progressive Engagement Valving: A custom-tuned internal shim stack provides reduced harshness during initial compression to ensure a smoother ride over small road imperfections.
• Gas Pressurization: High-pressure nitrogen charging provides consistent damping force and prevents oil foaming to ensure reliable performance during sustained towing or hauling.
• Twin-Tube Body: A 2.25-inch outer diameter steel housing provides increased oil capacity and physical protection for the internal piston to ensure long-term durability in harsh environments.
• Protective Boot: Included polyvinyl accordion boots provide a physical barrier against road debris and moisture to ensure the longevity of the polished chrome piston rod.

Frequently Asked Questions

Will these shocks lift my Ford F-350?
No, these shocks do not create lift. They are specifically configured for vehicles that already have a 4-inch suspension lift installed to ensure the piston operates within its optimal travel range.

What is the benefit of the RS5000X twin-tube design?
The twin-tube design is exceptionally durable; if the outer body is dented by a rock or debris, the inner cylinder remains unaffected, allowing the shock to continue functioning properly.

Do these fit Dual Rear Wheel (Dually) trucks?
No, these are specifically engineered for Single Rear Wheel (SRW) configurations and are not compatible with Chassis Cab or DRW models.
