Rancho RS5000X 2.5-4″ Rear Lift Shocks for 1972-1993 Dodge W100, W150 4WD

Part Number: RS55005

Summary: The Rancho RS5000X series utilizes a patented progressive engagement valving system to significantly improve the handling and ride quality of your classic 4WD Dodge or Plymouth. Designed for vehicles with 2.5 to 4 inches of rear lift, these twin-tube gas pressurized shocks provide the ideal balance of on-road comfort and off-road durability. The cross-tuned technology ensures that the shocks react instantly to changing terrain, providing a smooth street ride while maintaining firm control during trail use.

Features

• Progressive Engagement Valving: Custom-tuned velocity-sensitive discs provide a gradual transition between damping stages to ensure a smooth ride over small bumps while preventing bottoming out on harsh impacts.
• Gas Pressurization: High-pressure nitrogen gas charge provides a consistent response and prevents oil foaming to ensure fade-free performance in demanding environments.
• Twin-Tube Design: A 2.25-inch diameter reserve tube provides increased oil capacity and dent resistance to ensure long-term reliability in rugged off-road conditions.
• Protective Boot: Included polyvinyl accordion boot provides a physical barrier for the piston rod to ensure the seal remains free from debris and contaminants.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not provide lift. They are specifically configured for vehicles that already have 2.5 to 4 inches of rear lift installed.
