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

Part Number: RS55001 / RS55227

Summary: The Rancho RS5000X series leverages a unique Progressive Engagement Valving system to provide a smooth, controlled ride for the GMC K2500. Designed specifically for vehicles equipped with 2.5 to 4 inches of suspension lift, these shocks utilize a large 2.25-inch body to increase fluid capacity and dissipate heat more effectively than standard shocks. This twin-tube design focuses on rugged durability and dent resistance, ensuring consistent performance during both daily commuting and light off-road use.

Features

• Progressive Engagement Valving: Custom-tuned internal discs provide a gradual transition between low and high-speed damping to ensure a smooth ride over varied terrain.
• 2.25-inch Twin-Tube Body: An enlarged outer housing provides increased oil capacity to reduce internal temperatures and prevent shock fade during sustained cycling.
• Nitrogen Gas Pressurization: A pressurized gas charge minimizes aeration and foaming to ensure consistent hydraulic performance in demanding conditions.
• Protective Boot: A durable red polyvinyl accordion boot protects the piston rod from debris and stone chipping to ensure long-term seal integrity.
