Rancho RS5000X 0″ Lift Shocks for 1977-1979 Ford F-100, F-150 4WD

Part Number: RS55117

Summary: The Rancho RS5000X series leverages a patented progressive engagement valving system to significantly improve the ride quality of your 4WD Ford or International vehicle. Designed for stock height applications, these twin-tube shocks feature a cross-tuned design that balances on-road comfort with off-road durability. By minimizing aeration and shock fade through high-pressure gas equalization, these units provide a consistent damping force that handles the unique demands of classic truck geometries.

Features

• Progressive Engagement Valving: Custom-tuned internal discs provide a gradual transition between damping stages to ensure smooth street handling and controlled off-road performance.
• Twin-Tube Gas Pressure: The nitrogen-charged 2.25-inch body provides increased fluid capacity to ensure lower operating temperatures during extended use.
• Double-Welded Mounts: Reinforced loop-to-loop endings provide maximum structural integrity to ensure the shocks withstand the stresses of heavy-duty 4WD applications.
• Nitro-Carburized Piston Rod: A heavy-duty 16mm rod construction provides superior scuff resistance to ensure long-term seal life in harsh environments.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks are configured for vehicles with 0 inches of lift and are designed to replace factory-length dampers without changing vehicle height.

Is the hardware included for installation?
Yes, these shocks include the necessary bushings and protective red boots; however, you will typically reuse your factory mounting bolts.

Are these shocks nitrogen charged?
Yes, the RS5000X uses a high-pressure nitrogen gas charge to prevent oil foaming and ensure consistent performance under load.
