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

Part Number: RS55227

Summary: The Rancho RS5000X series features a cross-tuned twin-tube design engineered to provide a significant upgrade over factory damping for lifted applications. By utilizing a patented progressive engagement valving system, these shocks minimize harshness during initial impacts while maintaining firm control during aggressive maneuvers. Specifically configured for Chevy and GMC trucks with 2.5 to 4 inches of rear lift, they offer the perfect balance of on-road comfort and off-road durability.

Features

• Progressive Engagement Valving: Custom-tuned internal discs provide a smooth transition between low-speed and high-speed damping to ensure consistent ride quality across varying terrains.
• Large Shock Body: A 2.25-inch reserve tube provides increased oil capacity to ensure cooler operating temperatures during heavy hauling or off-road use.
• Gas Pressurization: Low-pressure Nitrogen gas charge provides a consistent response by minimizing aeration and foaming to ensure reliable performance under load.
• Nitro-Carburized Piston Rod: Heavy-duty construction provides superior resistance to scuffs and corrosion to ensure a long-lasting seal life in harsh environments.

Frequently Asked Questions

Will these shocks lift my truck?
No, these shocks do not create lift. They are specifically valved and sized to accommodate vehicles already equipped with 2.5 to 4 inches of rear lift height.

What is the benefit of the RS5000X twin-tube design?
The twin-tube design is highly durable; the outer tube can take a dent from a rock or debris without affecting the inner piston movement, ensuring you aren’t stranded on the trail.

Are boots included with these shocks?
Yes, Rancho RS5000X shocks include protective red boots to shield the piston rod from dirt, mud, and road grime.
