Rancho RS5000X 2.5-4″ Lift Shocks for 1969-1986 Chevy K-20 4WD
Part Number: RS55001
Summary: The Rancho RS5000X series leverages a patented progressive rebound and compression disc system to provide a significant upgrade in ride quality for lifted applications. Engineered for the Chevy K-20, these gas-pressurized twin-tube shocks are designed to handle the rigors of off-road terrain while maintaining smooth street manners. The larger shock body allows for increased fluid capacity, ensuring cooler operation and consistent damping performance during extended use.
Features
- Crossed Landscape Valve System: Patented progressive valving provides custom-tuned damping for both on-road comfort and off-road control to ensure a versatile driving experience.
- Gas Pressurization: High-pressure nitrogen gas charge provides reduced aeration and foaming to ensure consistent performance under heavy cycling.
- Double-Welded Mounts: Reinforced loop-style end mounts provide extreme structural integrity to ensure longevity in harsh environments.
- Protective Boot: Included red polyvinyl accordion boot provides a physical barrier for the piston rod to ensure seal longevity against debris.

Why Choose This Product?
- Engineering Advantage: Rancho’s patented valving technology transitions seamlessly between soft street damping and firm off-road resistance without manual adjustment.
- Performance Benefit: The twin-tube design offers a “fail-safe” outer wall, meaning a dent to the outer body will not restrict the inner piston’s movement, keeping you on the trail.

Frequently Asked Questions
Will these shocks lift my vehicle?
No, these shocks do not create lift. They are specifically configured with the correct extended and collapsed lengths to accommodate vehicles already equipped with a 2.5 to 4-inch suspension lift.
What is the benefit of the RS5000X gas charge?
The nitrogen gas charge minimizes the mixing of oil and air (foaming), which prevents the “fading” or softening of the shock’s damping force during aggressive driving.
Are boots included with these shocks?
Yes, this set includes Rancho’s signature red protective boots to shield the shock rods from rocks, mud, and road salt.
