Rancho RS5000X 2.5″ Rear Lift Shocks for 1999-2004 Ford F-350 4WD

Part Number: RS55254

Summary: The Rancho RS5000X Series gas-pressurized shock absorbers are engineered to provide enhanced durability and ride quality for your Ford F-350. Featuring a sophisticated twin-tube design, these shocks utilize a unique Progressive Engagement Valving system to minimize harshness during initial impacts. Designed specifically for vehicles with 2.5 inches of rear lift, they offer the perfect balance of off-road ruggedness and smooth street comfort.

Features

• Progressive Engagement Valving: Custom-tuned internal discs provide a gradual transition of damping force to ensure a smooth ride over variable terrain.
• Gas Pressurized Twin-Tube Body: The 2.25-inch diameter reserve tube provides increased oil capacity to ensure cooler operating temperatures during heavy-duty use.
• Nitro-Carburized Piston Rod: The heavy-duty 16mm rod construction provides superior scuff and corrosion resistance to ensure long-term seal integrity.
• Polyurethane Bushings: High-density mounting material provides reduced vibration transfer to ensure a quieter and more controlled cabin environment.

Frequently Asked Questions

Will these shocks lift my Ford F-350?
No, these shocks do not create lift. They are specifically dimensioned to work with vehicles that have already been modified with a 2.5-inch rear lift kit.

What is the benefit of the RS5000X over a standard shock?
The RS5000X features Cross-Tuned technology and a larger 2.25-inch body, which handles heat and heavy loads significantly better than standard O.E. replacements.

Are these compatible with Chassis Cab models?
No, these shocks are designed for standard pickup bed models and are explicitly not compatible with Chassis Cab configurations.
