Rancho RS5000X 2.5″ Front Lift Shocks for 1972-1975 Jeep CJ5, CJ6 2WD

Part Number: RS55113

Summary: The Rancho RS5000X series is engineered to provide a significant upgrade in ride quality and durability for your classic Jeep or FJ-9. Utilizing a sophisticated gas-pressurized twin-tube design, these shocks are specifically configured for 2.5-inch front lift applications to maintain proper suspension geometry. The RS5000X features an innovative Progressive Engagement Valving system that minimizes harshness during initial impacts while providing firm control during aggressive driving, making it the ideal solution for both daily street use and rugged trail conditions.

Features

• Progressive Engagement Valving: A custom-tuned internal shim stack provides increased damping control during high-velocity impacts to ensure a smooth, controlled ride on uneven terrain.
• Twin-Tube Gas Pressure: The nitrogen-charged 1.375-inch bore provides consistent oil-to-gas separation to prevent aeration and hydraulic fade during extended use.
• Nitro-Carburized Piston Rod: The heavy-duty 16mm rod construction provides superior corrosion resistance and surface hardness to ensure long-term seal integrity.
• Protective Boot Included: A durable red polyvinyl accordion boot provides a physical barrier for the rod and oil seal to prevent damage from debris and moisture.

Frequently Asked Questions

Will these shocks lift my Jeep?
No, these shocks do not create lift. They are specifically sized and valved to work with vehicles that already have a 2.5-inch front lift kit installed.

Are these shocks sold as a pair?
Yes, this specific SKU (2xRS55113_n775) includes two (2) front shocks for a complete front axle installation.

What is the benefit of the twin-tube design?
The twin-tube design is highly durable for off-road use; if the outer tube is dented by a rock, the inner cylinder remains unaffected, allowing the shock to continue functioning.
