Rancho RS5000X 2.5-4″ Rear Lift Shocks for 1969-1986 Chevy K-20 4WD

Part Number: RS55112

Summary: The Rancho RS5000X series leverages a patented progressive rebound and compression disc system to enhance the handling of your Chevy K-20. Designed for vehicles with 2.5 to 4 inches of rear lift, these gas-pressurized twin-tube shocks provide a significant upgrade in durability and impact absorption. The twin-tube design ensures high resistance to off-road debris and dents, maintaining smooth street comfort while managing the heavy-duty requirements of a 4WD truck.

Features

• Crossed-Tuned Technology: A specialized valve system provides custom-tuned damping to ensure consistent ride quality across varying terrains.
• Gas Pressurization: High-pressure nitrogen gas charge reduces oil foaming and aeration to provide fade-free performance during extended use.
• Twin-Tube Body: A 2.25-inch diameter reserve tube provides increased oil capacity to ensure cooler operating temperatures and better dent resistance.
• Protective Boot: A heavy-duty polyvinyl accordion boot provides a physical barrier for the piston rod to ensure long-term seal integrity.

Frequently Asked Questions

Will these shocks lift my Chevy K-20?
No, these shocks do not provide lift. They are specifically configured for vehicles that already have 2.5 to 4 inches of aftermarket rear lift installed.

What is the benefit of the RS5000X twin-tube design?
The twin-tube design is exceptionally durable; if the outer tube is dented by a rock or debris, the inner cylinder and piston remain unaffected, allowing the shock to continue functioning.

Does this include all necessary hardware?
Yes, this pair of shocks comes with the required bushings and protective boots for a direct-replacement installation.
