Rancho RS5000X 2.5″ Lift Shocks for 1984-1991 Jeep Grand Wagoneer SJ 4WD

Part Number: RS55118

Summary: The Rancho RS5000X series leverages advanced CrossTune technology to provide a significant upgrade over factory dampening for your classic 4WD. Engineered with a large 2.25-inch reserve tube, these twin-tube gas pressurized shocks are specifically valved to handle the weight and geometry of a 2.5-inch lifted Jeep. This setup delivers a refined street ride while maintaining the rugged durability required for off-road excursions, effectively neutralizing harsh impacts through a unique progressive engagement system.

Features

• CrossTune Technology: A unique progressive rebounding valving system provides a custom-tuned compression and rebound stroke to ensure consistent control during both highway cruising and trail use.
• Twin-Tube Gas Pressure: A 150 PSI nitrogen gas charged design provides a dedicated pressure barrier to ensure reduced aeration and foaming for more reliable damping performance.
• 2.25-inch Reserve Tube: An increased fluid capacity provides greater heat dissipation to ensure the shocks maintain optimal operating temperatures under heavy loads.
• Protective Boot: A heavy-duty red polyvinyl accordion boot provides a physical shield for the piston rod to ensure long-term seal integrity against debris and corrosion.

Why Choose This Product?

• Engineering Advantage: Rancho’s CrossTune system utilizes a larger internal piston area than standard shocks, allowing for more precise tuning of the compression and rebound cycles.

Frequently Asked Questions

Will these shocks lift my Jeep Grand Wagoneer?
No, these shocks do not create lift. They are specifically valved and length-matched for vehicles that already have a 2.5-inch suspension lift installed.

What is the benefit of the RS5000X gas charging?
The 150 PSI nitrogen charge minimizes the mixing of oil and air (foaming), which prevents “shock fade” and maintains consistent damping during rapid suspension cycling.

Are these shocks sold as a complete set?
Yes, this specific SKU (2xRS55118_2xRS55118) includes a full set of four shocks to outfit the front and rear of your vehicle.
