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

Part Number: RS55227

Summary: The Rancho RS5000X series utilizes an advanced Cross-Tuned twin-tube design to significantly improve the ride quality of your lifted GMC Yukon or Chevy K2500. Engineered specifically for vehicles with 4 inches of rear lift, these shocks manage the increased unsprung weight of larger tires while maintaining smooth street comfort. The gas-pressurized architecture reduces fluid aeration, ensuring consistent damping performance during heavy-duty hauling or off-road excursions.

Features

• Progressive Engagement Valving: Custom-tuned compression and rebound circuits provide a smooth initial response to ensure comfort during daily driving.
• Gas Pressurization: High-pressure nitrogen charging provides a reduction in oil foaming and cavitation to ensure consistent performance under load.
• 16mm Nitro-Carburized Rod: The heavy-duty hardened piston rod provides increased structural rigidity to ensure long-term durability in harsh environments.
• Self-Lubricating Seal: A specialized PTFE-coated seal provides a reduction in friction and heat to ensure a longer service life and leak protection.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically sized and valved to work with a vehicle that has already been equipped with a 4-inch rear lift kit.

What is the benefit of the twin-tube design?
The twin-tube design provides an outer chamber for oil reserve, making the shock more resistant to debris or dents while maintaining a plush ride quality.

Are boots included with these shocks?
Yes, these shocks include protective boots to shield the piston rod from dirt, salt, and road debris.
