Rancho RS5000X 2.5-4″ Rear Lift Shocks for 1969-1991 GMC Jimmy 4WD

Part Number: RS55112

Summary: The Rancho RS5000X series utilizes a cross-tuned twin-tube design to provide a significant upgrade in ride quality for lifted applications. Engineered for the 1969-1991 GMC Jimmy 4WD, these shocks are configured for 2.5 to 4 inches of rear lift, balancing off-road durability with smooth street performance. The gas-pressurized twin-tube construction ensures consistent damping by minimizing fluid aeration during cycling.

Features

• Progressive Engagement Valving: Custom-tuned compression and rebound circuits provide a smoother transition between damping forces to ensure maximum comfort on uneven terrain.
• Gas Pressurized Twin-Tube: High-velocity nitrogen gas charges the hydraulic fluid to provide rapid response times and prevent cavitation during high-frequency cycling.
• 10.41-Inch Stroke: An extended travel architecture provides increased articulation to ensure the tires maintain contact with the ground during off-road maneuvers.
• Protective Boot: A heavy-duty red polyvinyl boot protects the piston rod from debris to ensure long-term seal integrity.

Frequently Asked Questions

Will these shocks lift my GMC Jimmy?
No, these shocks do not create lift; they are specifically length-tuned to accommodate 2.5 to 4 inches of lift height provided by your leaf springs.

Are these shocks sold as a pair?
Yes, this specific SKU (2xRS55112) includes a pair of two (2) rear shocks.

What is the benefit of the gas charge in the RS5000X?
The nitrogen gas charge keeps the internal hydraulic oil under pressure, which prevents foam from forming (aeration) during hard use, maintaining consistent damping performance.
