Rancho RS5000X 2.5-4″ Rear Lift Shocks for 1988-2000 GMC K2500 4WD

Part Number: RS55190

Summary: The Rancho RS5000X series utilizes a cross-tuned twin-tube gas pressurized design to enhance the handling and stability of your GMC K2500. Engineered specifically for vehicles with 2.5 to 4 inches of rear lift, these shocks feature a unique progressive engagement valving system that minimizes initial impact harshness. This setup provides durable dent resistance and smooth street comfort, making it an ideal solution for leveled or lifted trucks requiring consistent performance across varying terrains.

Features

• Cross-Tuned Technology: A specialized valve base provides a unique compression and rebound tune to ensure improved handling and control on-road and off.
• Progressive Engagement Valving: Custom-tuned internal discs provide a gradual transition during high-velocity impacts to ensure a smoother ride quality and reduced harshness.
• Nitrogen Gas Pressurization: A high-pressure gas charge provides a barrier against oil foaming to ensure consistent damping performance during spirited driving.
• Nitro-Carburized Piston Rod: A 16mm heavy-duty rod construction provides increased structural integrity to ensure long-term durability in harsh environments.

Frequently Asked Questions

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

What is the benefit of the twin-tube design?
The twin-tube design is highly durable for off-road use; if the outer body is dented, the inner cylinder remains unaffected, ensuring the shock continues to function properly.

Are the boots included with these shocks?
Yes, these RS5000X shocks include the signature Rancho red protective boots to shield the piston rod from debris.
