Rancho RS5000X 4″ Lift Shocks for 1981-1993 Ford Bronco 4WD

Part Number: RS55117 / RS55118

Summary: The Rancho RS5000X series utilizes an innovative cross-tuned twin-tube design to provide a significant upgrade in ride quality for lifted applications. Specifically configured for 4-inch lifts, these shocks employ a unique valving system that minimizes harshness during initial impacts while maintaining firm control over larger obstacles. This makes them the ideal solution for Ford Bronco owners seeking a balance between rugged off-road durability and smooth street comfort.

Features

• Cross-Tuned Technology: A specialized valve base provides a progressive engagement of the fluid circuit to ensure a smoother ride on washboard surfaces.
• Twin-Tube Design: The 2.25-inch reserve tube provides increased oil capacity to ensure cooler operating temperatures during extended use.
• Nitrogen Gas Pressurization: A high-pressure gas charge minimizes aeration and foaming to ensure consistent damping performance in demanding conditions.
• Protective Boot: A heavy-duty red polyvinyl accordion boot protects the piston rod from debris to ensure long-term seal integrity.

Frequently Asked Questions

Will these shocks lift my Ford Bronco by 4 inches?
No, these shocks do not create lift. They are specifically length-tuned to work with a Bronco that already has a 4-inch suspension lift installed.

What is the benefit of the RS5000X over the original RS5000?
The RS5000X features a larger body and a refined valving system that provides better heat dissipation and a smoother transition between compression and rebound.

Are the boots included with these shocks?
Yes, this set includes Rancho’s signature red protective boots to keep the shock rods clear of dirt and grime.
